Fertility Apps Can Help Track Fertility
The mobile revolution has extended to many parts of our life, and is just starting to dramatically improve pregnancy and fertility outcomes. Fertility apps now enable women to pinpoint the best time to conceive, track cycles, and beyond. These new apps are arriving at the same time that attitudes towards openly discussing fertility among women and between partners are changing. Right now, new providers such as Ava, Daysy, and Natural Cycle are the leading fertility apps, and leading this mobile app and data-driven revolution.
As usage of these apps climb, it’s also becoming clear that people are interested in using these apps for different purposes. These apps can not only help couples get pregnant, but also help them avoid getting pregnant. One major advantage of using these new apps is the cost and time savings. Previously, women had to rely on expensive in person visits to get this same information. Now, women can do everything with the touch of a few buttons, which is exactly what we like!

Natural Cycles Basics
Is it worth it? We discuss
Natural Cycles was the first FDA-approved mobile app for understanding women’s fertility windows in order to help with birth control and pregnancy planning.
Like many ideas, the idea for Natural Cycles fulfilled a need that the cofounders had – to find an effective method of natural birth control that didn’t include the use of hormones. Co-Founders Elina and Raoul began to document Elina’s own temperature and together they created an algorithm that determined fertile days. Not only did the algorithm work for contraception, but it also helped them plan successful pregnancies. Since then Natural Cycles has been a leader in empowering women to learn more about their bodies.

The Verdict
Our experience with Natural Cycles
Many of those coming to Natural Cycles are looking for hormone-free birth control and cycle tracking.
They may also be tired of their current system of trying to track their fertility on their own. Our bodies are different, and while Natural Cycles has positive reviews overall, it might work differently for you.
We recommend taking a look at the fine print, and we did see some reviews that discuss being charged for a renewal that they didn’t expect – so always be aware!
Ava Tracker Basics
Ava Bracelet and App Tracker Overview
Starting in 2014, Ava has been focused on providing data-driven insights to help women with infertility. Focusing on their wearable device, Ava has published more than 30 peer-reviewed clinical papers and has become the first wearable fertility tracker with FDA clearance.
One unique aspect of Ava is the way that it measures temperature: through the wrist. Ava has done research to compare the difference between reading basal body temperature through the mouth and through the wrist and has found wrist skin temperature was potentially more accurate (you can check that article out here).

What customers are saying
The Verdict
Our experience with the Ava Tracker
Ava bracelet users love how simple the device is to use and how much more convenient it is than other fertility trackers.
Instead of manually running tests every morning, the bracelet does all the work for you. There have been some complaints that data cannot be synced, but the customer service department was also praised in how it helped customers troubleshoot.
Daysy Tracker Basics
Daysy App and Dasys Thermometer Overview
Daysy’s vision is to help women connect with their own “body intelligence” through fertility tracking. Similar to Natural Cycles, Daysy uses BBT and menstruation data to help women understand their most fertile days. Daysy relies on a combination of technologies:
- A precise BBT temperature sensor
- A unique, intelligent algorithm based on a database of 5 million menstrual cycles
- An intuitively designed tracking App.

The Verdict
Our experience with the Daysy Tracker
Like Natural Cycles, people come to Daysy to find hormone-free fertility options. We found the online reviews of Daysy to be overwhelmingly positive when it comes to tracking fertility.
But all of our bodies are different, so you’ll need to find the device that works best for you. Another consideration is that like Natural Cycles, Daysy requires you to use the device as intended, which means taking measurements with the thermometer.
