FAQs
What is the primary difference between Tempdrop and the Apple Watch?
The most significant difference lies in their core purpose and technology. Tempdrop is a wearable sensor designed specifically for tracking basal body temperature (BBT) and helping women monitor fertility and ovulation. It’s worn on the upper arm at night and provides temperature readings that align with natural hormone fluctuations. In contrast, the Apple Watch is a multi-functional smartwatch that includes general wellness and health features, such as activity tracking, heart rate monitoring, and recently, skin temperature sensing. However, the Apple Watch’s temperature data is broader and less focused on fertility metrics, making Tempdrop the more accurate choice for women tracking their cycles.
Is Tempdrop more accurate for fertility tracking than Apple Watch?
Yes, Tempdrop is significantly more accurate for fertility tracking. It continuously measures BBT throughout the night, filtering out data affected by restlessness or environmental changes. Its algorithm adjusts to your unique cycle over time, making it a robust tool for natural family planning, TTC (trying to conceive), or fertility awareness. The Apple Watch, while sophisticated, provides skin temperature estimates during sleep, which may vary widely due to wrist exposure and is not calibrated specifically for fertility prediction.
Can I use Tempdrop and Apple Watch together?
Absolutely. Many women pair Tempdrop for fertility tracking with the Apple Watch for daily health insights. Using both can give you a more comprehensive understanding of your body—Tempdrop gives deep insight into your reproductive health, while Apple Watch supports general wellness tracking, including fitness, heart rate, and sleep stages. They complement each other well if your goal is holistic health management.
Which one is better for tracking sleep quality?
While both devices offer sleep tracking, Apple Watch excels in overall sleep quality tracking. It provides detailed insights into sleep stages (REM, Core, and Deep sleep), duration, and heart rate variability during sleep. Tempdrop also tracks sleep duration and restlessness, but its primary focus remains on temperature trends, not sleep phases. For detailed sleep analytics, Apple Watch has the edge.
Does Tempdrop sync with fertility tracking apps?
Yes, Tempdrop syncs with popular fertility tracking apps like OvuView, Kindara, Fertility Friend, and Read Your Body. This integration allows users to chart their BBT data seamlessly, improving the accuracy of ovulation predictions. Apple Watch doesn’t directly integrate with these apps, though some third-party apps may pull limited data like sleep and temperature trends.
Is the Apple Watch reliable for tracking ovulation?
Apple Watch includes cycle tracking and shows retrospective ovulation estimates based on temperature trends and logged menstrual data. However, it’s not designed for real-time ovulation prediction. Its temperature sensor captures wrist skin temperature, which fluctuates easily and lacks the granularity of BBT. Tempdrop, in contrast, offers more consistent ovulation tracking tailored to fertility monitoring.
How long does Tempdrop take to learn my cycle?
Tempdrop typically requires about 1-2 months to calibrate and learn your unique temperature patterns. Its algorithm becomes more accurate over time, adapting to your sleep environment and cycle characteristics. The Apple Watch doesn’t have this adaptive feature for temperature; instead, it displays nightly variations without learning or improving predictions.
Do both devices require wearing overnight?
Yes, but with key differences. Tempdrop must be worn overnight on the upper arm, ideally snugly under your sleepwear. It gathers temperature data throughout the night to detect your true BBT. The Apple Watch is worn on the wrist and should be worn during sleep to monitor skin temperature changes and sleep patterns. However, some users find sleeping with a watch uncomfortable, making Tempdrop the lighter, more sleep-friendly option.
Which device is more comfortable to wear overnight?
Many users find Tempdrop more comfortable overnight because of its soft, armband-style design that doesn’t involve wrist straps or pressure. It’s discreet and lightweight, designed specifically for nighttime use. On the other hand, some users report that the Apple Watch can feel bulky, especially for side sleepers or those sensitive to wristwear during rest.

Tempdrop wins hands down with a battery life of up to 6 months on a single coin-cell battery. It doesn’t require frequent charging, making it hassle-free. In contrast, Apple Watch must be charged daily or every 1–2 days, depending on the model and usage. If you forget to charge it, you might miss valuable sleep data.
Can Apple Watch replace a fertility thermometer?
Not entirely. While Apple Watch can show nightly temperature changes, it doesn’t measure basal body temperature accurately or consistently enough to be a replacement for a traditional BBT thermometer or Tempdrop. It lacks cycle-specific analytics and adaptive algorithms. Tempdrop, designed for this purpose, provides fertility-specific data that’s validated and chartable.
Which device is better for TTC (Trying to Conceive)?
Tempdrop is the better choice for women actively TTC. Its BBT tracking accuracy, integration with fertility apps, and cycle-learning algorithm make it a powerful tool for understanding fertile windows. Apple Watch lacks the precision and fertility-focused features needed for serious conception efforts, making it more suitable for general wellness than TTC goals.
Is there a subscription fee for Tempdrop?
No, Tempdrop does not require a subscription. You purchase the device once and gain full access to its features, including syncing with fertility apps. Apple Watch, however, may require subscriptions for premium features through third-party apps or Apple Fitness+, depending on what you’re tracking.
Can I use Apple Watch for Natural Cycles or similar apps?
Apple Watch now integrates with Natural Cycles, a fertility tracking app FDA-approved for birth control. However, it still relies on wrist skin temperature, which is less accurate than BBT. Natural Cycles itself recommends Tempdrop or oral thermometers for more reliable readings. So while integration exists, it’s not the optimal sensor for effectiveness.
How does Tempdrop filter out disturbed sleep?
Tempdrop’s algorithm is designed to filter out poor-quality or disturbed sleep that could skew temperature readings. It uses motion sensors and smart filtering to ensure only stable temperature readings contribute to your BBT data. Apple Watch does not offer such filtering in its temperature tracking, which may lead to more noise in the data.
Is Apple Watch worth it if I only want fertility tracking?
If fertility tracking is your only goal, Apple Watch is likely not worth the investment. It’s a premium device with a broad range of features unrelated to fertility. Tempdrop, being more affordable and purpose-built, offers higher value and greater accuracy for this specific need. However, if you also want a smartwatch for workouts, messages, and health, then Apple Watch might be a better all-around tool.
Which one is easier to set up and use?
Tempdrop is very easy to set up. You attach it to your upper arm, sync it via Bluetooth in the morning, and you’re done. No screen, no apps running in the background. Apple Watch, on the other hand, requires more configuration, app permissions, and consistent charging. For simplicity and low maintenance, Tempdrop is more user-friendly.
Can Apple Watch detect early pregnancy?
While Apple Watch may show elevated skin temperature patterns that align with early pregnancy, it’s not designed to detect pregnancy or offer accurate predictions. Tempdrop’s continuous BBT tracking may show a sustained rise in temperature post-ovulation, a potential early pregnancy sign, but neither device is a substitute for a pregnancy test.
Which is better for long-term health tracking?
For overall long-term health and wellness tracking, Apple Watch is better. It monitors heart rate, blood oxygen, activity levels, notifications, ECG, and more. Tempdrop, however, specializes in reproductive health and is ideal for long-term fertility charting and hormone-based cycle analysis. Each serves a different purpose depending on your health goals.
