Frequently Asked Questions
1. Which smartphones work with the iThermonitor app?
a. Apple devices with iOS BLE 4.0 and iOS 8.0 and above.
b. Android devices with BLE 4.0 and Android 4.4 and above.
2. How can I remotely monitor my child's temperature?
a. Ensure connection between local smart phone and iThermonitor. Then you can sign on to the same iThermonitor account from a different smart phone and the app will automatically mirror the data.
3. What do the LED indicator lights indicate?
a. A single blink at one-second intervals indicates that the thermometer needs to be connected with the mobile app on a smart phone or iOS tablet in order to sync.
b. A single blink at four-second intervals indicates that the thermometer's power is on.
c. The LED remaining lit indicates low power and that the battery needs to be charged or changed.
4. How long can a single patch be used for?
a. We suggest not wearing the patch for more than 24 hours in the same position and moving the iThermonitor to the other armpit if needed.
b. Note: We suggest that parents check from time to time to make sure there is no skin irritation.
5. Having trouble staying connected?
a. The iThermonitor uses Bluetooth 4.0 technology, meaning it’s a low energy connection so that it is safe and saves power. For this reason we suggest keeping the smartphone in use within ten feet of the device, even though the range may be larger. Increasingly, keeping the smartphone on the same side of the body that the iThermonitor is attached to will also improve connection.
b. In order to ensure a smooth user experience the app alerts you when there is a disconnection and it will automatically reconnect when the device comes back within range.
6. What is iThermonitor's battery life?
a. At 8 hours per day the battery should last 120 days, however, frequent disconnection and reconnection may deplete the power more quickly.
b. Battery type: CR2025.
7. What should I be aware of with multitasking in iOS?
a. When the app leaves the active screen and enters the background, or when the screen is locked, iOS by default disconnects the wireless connection to save battery power. This does not mean the Bluetooth connection is severed. iThermonitor will continue monitoring temperature even when the app isn’t physically displayed on your screen. However, when the app is in the background you can only monitor temperature locally, not remotely.
b. Also, if the app is running in the background and the device becomes disconnected the automatic reconnection feature will not work. Even local temperature monitoring will not work in this case.
8. How can I reorder patches?
a. You can reorder patches on Amazon (https://www.amazon.com/FridaBaby-011-Fridababy-FeverFrida-Adhesive/dp/B01644OCPE).
b. Contact your original vendor.
c. Or you can simply contact us via email at email@example.com.
9. Does iThermonitor accurately record core temperature?
a. In one word, yes! iThermonitor is one of the very few clinically validated consumer thermometers. In other words, our device has been tested in clinical trials to compare its reading of core temperature with one of the current gold standards for core temperature monitoring in operating rooms. The conclusions were that iThermonitor can be used in clinical settings, including important surgeries, as an accurate reference point for doctors.
10. Why are core temperature readings better than axillary measurements?
a. Core temperature refers to a measurement of temperature in deep structures of the body, which is considered by most medical professionals to be the best reading of the body’s real temperature. Axillary or traditional methods of body temperature measurements, no matter how accurate they may be, normally provide the temperature of that specific spot on the body in which the thermometer is placed. Thus, devices that reflect an accurate reading of core temperature are more able to support doctors in clinical decision making.
About the iFertracker
1.What is the iFertracker?
The iFertracker is a wearable thermometer used to measure basal body temperature to predict ovulation date and fertile window for women who are trying to conceive.
2.What does the iFertracker do?
By wearing the iFertracker while sleeping, then syncing it with the iFertracker app on a mobile device in the morning, women can measure the basal body temperature, which is the lowest body temperature during sleep, attained in a stable state during the whole night. The iFertracker app coverts the daily basal body temperatures into graphic form to reflect the BBT change before and after the ovulation. The app informs users the current stage of their menstrual cycle, records relevant events, reminds them to take medicine, and predicts the timing of ovulation. This helps women to plan sexual intercourse to get pregnant and manage their menstrual cycle in a smart way.
3.Who should use the iFertracker?
Women in reproductive age who are trying to conceive. The iFertracker can be used before or during pregnancy, to prepare for pregnancy, and to monitor the risk of miscarriage.
4.Is it safe for the iFertracker directly contacts with a person's skin?
Completely. The materials used for this product meet biocompatibility and RoHS standards.
a. The product has passed tests on cytotoxicity, irritation, skin sensitization, and meets the requirements of “Biological evaluation of medical devices — Part 5: Tests for in vitro cytotoxicity”. The product has passed tests on "Biological evaluation of medical devices —Part 10 : Tests for irritation and delayed-type hypersensitivity ".
b. The product complies with Rohs2011/65/EU requirements. It also complies with the requirements of EC 62321:2008 " Electro technical products — Determination of levels of six regulated substances (lead, mercury, cadmium, hexavalent chromium, polybro-minated biphenyls.)".
5.Does the iFertracker emit radiation?
The iFertracker does not connect with the app while worn. The iFertracker uses Bluetooth 4.0 (Bluetooth low energy) technology when syncing data in the morning, meaning it emits far less radiation than a mobile phone. It fully complies with electromagnetic radiation standards.
Please refer to WHO: Electromagnetic fields and public health: Mobile phones
6.Are the patches safe?
In order to guarantee the best user experience, we tested about 80 different types of patch and chose the adhesive patch from well-known brand 3M. On top of this, we reduced the area of skin contact with the patch, and finally designed a circular double-sided patch for the best wearing experience.
We recommend that users use the adhesive patches we provide, and that the device be worn in the environment of room temperature. We recommend it not be worn for more than 24 consecutive hours on the same spot. The patches provided with this product are hypoallergenic. However, if skin irritation occurs, stop using the iFertracker immediately and refer to your doctor for other adhesives.
7.How accurate are the measurements?
The accuracy of the iFertracker has been officially approved to be:
±0.1℃ (25-34.99℃, 38.51-45℃)
±0.18℉ (<94.9°F and >101.3℉)
8.Why does the iFertracker give different results than mercury thermometers?
1.Temperature measurement results vary depending on the part of the body used, though all are close to the internal core temperature, what we describe as body temperature. Traditional basal body temperature measurement entails using a mercury thermometer orally. The iFertracker basal body temperature thermometer measures axillary (armpit) temperature. Oral measurements give a higher result than axillary temperature; clinical research shows a 0.5℃/0.9℉difference between armpit temperature and rectal temperature, and a 0.74-1.34℃/1.33-2.41℉ difference between ear temperature and rectal temperature.
2.Taking your temperature at different times leads to different results. Traditional basal body temperature is taken immediately after waking up, while the iFertracker measures it during sleep. (True basal body temperature is about 30 minutes prior to waking.)
3.Different thermometers give different results. Mercury thermometers allow for a margin of error of +0.10℃ to -0.15℃/+0.18℉ to -0.27℉, while the iFertracker, within the normal temperature range of a human body (35-38.5℃/95-101.3℉), has a margin of error of ±0.05℃/±0.09℉.
1.How to use the iFertracker...
The iFertracker is worn under the armpit before the user goes to sleep, and taken off when she wakes up the next morning. The iFertracker syncs its data with the iFertracker app on a mobile device via Bluetooth in order to provide daily basal body temperature measurement.
2.How is the iFertracker turned on and off?
After putting in the battery, hold the iFertracker in your hand until the LED indicator blinks once a second. (The first time you use it, you will need to connect the iFertracker with the app on your mobile device to sync the time). If the battery has enough power, you don’t need to connect with the app beforehand except the first time; you can simply wear it, and the iFertracker will automatically turn on. After removing it in the morning, put the iFertracker aside at room temperature; when it senses the drop in temperature, it will turn itself off automatically.
3.What is a firmware update?
In order to improve the function of iFertracker firmware, we will provide updates to the iFertracker device when needed. The iFertracker app will notify you once the firmware update is available. The update will be done by opening the iFertracker app on your mobile device and following the instructions.
4.How are the patches used?
Peel off the white side of the patch and stick it on the side with metal part (the temperature probe) and Raiing logo. Make sure the patch does not go beyond the border of the sensor, then peel off the transparent layer of the patch and attach the sensor to the armpit to begin tracking temperature.
5.What is the correct position of the iFertracker?
The metal part of the sensor should firmly contact the skin inside the armpit. Shave your armpit before wearing and ensure that when the arm is held tightly to the side, the armpit covers the whole iFertracker.
6.What should I pay special attention to while wearing the iFertracker?
For a more comfortable wearing experience, we suggest that you shave your armpit before using the iFertracker. Wear the iFertracker for a minimum of four to six hours a night, during sleep. Basal body temperature data will not be collected if you wear it less than 4 hours or wear it too low in your armpit.
7.What should I do if the iFertracker comes off while I sleep?
Put it back in the suitable position in your armpit if this happens. However, if the iFertracker is out of your armpit longer than 30 mins it will not be able to find the lowest body temperature point in a stable sleep state, and will tell you that the basal body temperature has not been recorded. If it falls off frequently, we suggest you change patches, shave your armpit, and clean skin with water or medical alcohol before wearing.
8.What happens if I forget to use the iFertracker?
If you forget to use the iFertracker when basal body temperature is about to change, the app will not obtain basal body temperature data, the app will not be able to predict the date of ovulation, or divide your menstrual cycle into the safe period and the fertility window.
9.Will the temperature measurement be affected if I use the bathroom at night?
No. The iFertracker automatically filters the disruption when you use the bathroom at night.
10.How do I sync data?
Syncing data is very easy. You only need to take off the iFertracker and place it next to your mobile device with the iFertracker app open. Wait for the data upload automatically and the BBT reading will display at the end of data processing.
11.Do I need to sync with the app every day?
We suggest that you sync the iFertracker with your iFertracker app on the mobile device with Internet access every day as soon as you wake up, especially around the dates of ovulation, to get the result of the data analysis as soon as possible, and find out what your basal body temperature is that day. However, the iFertracker saves data for up to 10 days, so if you don't have time to sync every day, you can find a convenient time to sync multiple days in one go.
12.What is the LED indicator for?
1. A single blink at one-second intervals indicates that the iFertracker needs to be connected with the mobile device in order to sync data.
2. A single blink at four-second intervals indicates that the iFertracker is on.
3. The LED remaining lit indicates low power and that the battery needs to be replaced.
13.What is the power supply? What is the battery life?
CR2025 watch battery in room temperature will last 45 - 60 days at 8 hours per day usage; however, firmware updating and frequent data syncing with app may deplete power more quickly.
14.I'm pregnant already. Do I need to continue wearing the iFertracker?
We suggest that you continue wearing the iFertracker for two to three months after becoming pregnant. During the first eight weeks of pregnancy, your progesterone level mainly depends on a section of the ovary called the corpus luteum. After eight weeks, the placenta gradually takes over. Basal body temperature can be used to measure your progesterone level. During the early stages of pregnancy, a sudden drop decrease in corpus luteum function may result in miscarriage and can be captured by decreased BBT. Corpus luteum function can be tracked through basal body temperature. This means that monitoring basal body temperature can help you pick up early signs of a risk of miscarriage and take actions accordingly.
15.What is the meaning of the color on the BBT chart?
Pink represents the period of menstruation. Orange indicates the best timing to try to conceive, Yellow represents the date of ovulation. Blue is the safe period, during which the chance of conception is low.
16.What should I do if, when I first log in, I don't remember the date of my last period?
Use your best estimate.
The date can be changed after you input it. However, the app requires a start date for at least one menstrual cycle, so if you have only input the start date of one menstrual cycle, it cannot be deleted.
17.Why do I need to input menstrual cycle and period length?
This information creates a database that allows the iFertracker to recognize different stages of the menstrual cycle and predict ovulation date. The changes in color on the calendar and the BBT chart correspond to this information.
18.Why do I need to record relevant events?
Using basal body temperature as a guide to conceive requests information such as sexual activity, sleeping quality, and mood, etc. The app can provide more accurate predictions of ovulation date with all relevant information.
19.How do I record relevant events?
1、Click on the on the right side of the Daily Status page, and choose from the list to start to record;
2、Click on the Calendar icon on the top right side of the Daily Status page, choose the specific date on which the event occurred, then click the below to input the record.
3、Enter the BBT page, choose the specific date on which the event occurred, then click the below to input the record.

Basal body temperature
1.What is the definition of basal body temperature?
Physiology, published by People’s Medical Publishing House (China):
When the human body is awake but very quiet, unaffected by factors of muscle movement, nervous tension, food, or environmental temperature, this is called basal status. The body temperature in basal status is called basal body temperature, and is usually measured in the morning after waking. Female basal body temperature changes with the menstrual cycle. Temperature is relatively low at the follicular phase, and lowest on the day of ovulation. After ovulation, body temperature rises by 0.3-0.6℃/0.54-1.08℉.
Family Planning: A Global Handbook for Providers, a 2012 WHO publication related to calendar-based contraceptive methods:
Basal body temperature – the body temperature of a fertile woman when
resting – rises after ovulation and remains high until the next menstruation.
Detailed method: Every day after waking up, immediately (before getting up or eating any food) measure body temperature and record it in a special designed form; after ovulation, body temperature usually rises 0.2-0.5℃/0.36-0.9℉ (this usually hap-pens at the middle stage of the menstrual cycle).
Basal body temperature is the lowest body temperature attained during rest (usually during sleeping). It is generally measured immediately after awakening and before any physical activity has been undertaken.
2.Why dose the basal body temperature rise after ovulation？
The rise of female basal body temperature during the menstrual cycle is the result of progesterone stimulating thermal homeostasis in the anterior pituitary gland.
3.Why is measuring basal body temperature important?
Progesterone in the female body peaks at ovulation and when the ovarian follicle develops into the corpus luteum after ovulation, so basal body temperature change (rise) indicates the day of ovulation. Considering the life span of sperm and egg, knowing which ovulation day can increase pregnancy possibility (possibility of conceive is high five days prior to the day of ovulation, and highest two days prior to the day of ovulation).
Other gynecological usages
•A luteal phase shorter than 12 days and a rise in body temperature of less than 0.3-0.6℃/0.54-1.08℉ means inadequate luteal function.
•Luteal phase (basal body temperatures rising) lasts for more than 20 days without dropping is considered signs of pregnancy.
•In the first three months of confirmed pregnancy, basal body temperature with a clear drop trend may be a sign of early miscarriage.
•In cases of anovulatory DUB (dysfunctional uterine bleeding) or induced ovulation of infertile women, basal body temperature change can be used to determine whether ovulation has taken place.
•In cases of women with abnormal vaginal bleeding, it is difficult to accurately determine menstrual cycle based on menstruation. Measuring basal body temperature can provide an accurate and reliable indication of the menstrual cycle.
•If basal body temperature is too high in gynecological endocrine patients, the possibility of pelvic tuberculosis and endometriosis should be considered.
4.What are the traditional methods of measuring basal body temperature?
Putting a thermometer under the tongue for five minutes immediately after waking up, recording body temperature number in a specially designed form, continuously measuring for one to three months while recording information on menstruation and cervical mucus, whether ill or not.
Since female basal body temperature only rises 0.3-0.6℃/0.54-1.08℉ after ovulation, normal mercury thermometer is not accurate enough due to their margin of error of 0.1℃/0.18℉, making it unsuitable for measuring basal body temperature. Many pregnancy preparation groups recommend using an electronic thermometer based on thermistor technology. Some thermometer manufactures have added recording and charting functions to their basal body temperature thermometers.
5.What are the differences between iFertracker and traditional methods?
Worn over night, the iFertracker collects a whole night of temperature data. And the advanced algorithm in the app provides the true basal body temperature, which is about 30 mins before awaking. The app also records the daily reading and converts to BBT chart automatically. The user can easily understand the rise (the ovulation day) from the chart and the notification of TTC in the app.
The data accuracy of the iFertracker makes it easier for doctors to evaluate basal body temperature and provide clinical advice. Clinical research shows that for women suffering from fertility problems while still having regular menstrual cycles, continuous measurement of whole-night body temperature predicts day of ovulation and ovulation cycle more accurately than ultrasonic monitoring of type-B follicle size.
6.Do irregular sleeping patterns affect basal body temperature?
A regular life routine leads more regular progesterone secretion, which is good for preparation of ovulation and conceive. Irregular sleeping habits may lead to progester-one secretion disorder, which affects menstrual cycle and ovulation. We suggest that you maintain a regular routine when trying to conceive, and that you wear the iFertracker regularly.
7.How is the Fertile Window calculated?
The adult menstrual cycle lasts 28-35 days in average. The follicular phase is the phase before ovulation, and the luteal phase is the phase after ovulation. The follicular phase often varies between 14-21 days; the luteal phase is normally consistent around 14 days.
The follicular phase is the phase before the day of ovulation. Taking into account the average life span of sperm and egg (sperm live for 3-5 days, eggs for less than a day), the fertile window is 12-17 days before the next menstruation.
8.Does increasing frequency of sexual intercourse during the fertile window increase pregnancy possibility?
Having sexual intercourse every two-three days gives the highest chances of conception. However, it is not clear whether increasing the frequency of sexual intercourse raises the chances of conception during the fertile window.
Medical research suggests that frequent sexual intercourse lowers sperm count and volume, but increases sperm quality. By having sexual intercourse every two days in the fertile window, male partners can not only save energy but also ensure their sperm count remains high. Sperm count is the key factors for conceive.
