Best Fertility Tracking App 2026: 8 Apps Compared for TTC

How We Picked These Apps

We shortlisted the 8 apps compared below from what people trying to conceive actually use, and compared them on the criteria that matter most here: BBT charting, LH/OPK test tracking, cervical mucus logging, and wearable integration. We checked each app's App Store listing (price, rating, privacy label, latest version) first-hand on October 16, 2026, along with its feature and pricing pages, and we read each app's current privacy policy rather than relying on its marketing pages.

Full disclosure: this site is published by Holland Neurotech Inc., the maker of Veya. The list isn't ranked — each app is presented as the fit for a specific need — we include our own app only where it genuinely belongs, and we say plainly when a competitor is the better choice.

The World Health Organization estimates that about 1 in 6 adults worldwide experience infertility at some point (WHO, 2023). If you're trying to conceive, timing matters: you have only a few fertile days each cycle, and the best odds come in the days just before ovulation. Miss that window and you're waiting another month.

A good fertility app helps you pinpoint that window. But not all apps do it the same way, and the differences matter. Some rely on calendar math (the least direct method). Others use your BBT data, LH test results, or wearable sensor readings. This guide compares 8 apps on how well they actually help you find your fertile window. If you're not yet sure what to track, see how to tell if you're ovulating for the body signals to look for first. For a rough fertile-window estimate before you start tracking signs, try the free ovulation calculator, which uses your last period and cycle length.

Educational content, not medical advice. If you have concerns about your fertility, or you've been trying to conceive for a while, please talk to a doctor or fertility specialist.

What does fertility tracking actually involve?

Fertility tracking means logging signs that show when you are likely to ovulate. Basal body temperature confirms ovulation after it happens, LH tests flag the surge that precedes it by one to two days (53 women, 150 cycles), and cervical mucus shows the fertile phase building. In a study of 221 women, conception occurred only in the six-day window ending on the day of ovulation. There are three main ways to track, and many apps support more than one.

Basal Body Temperature (BBT) Charting

Your resting body temperature typically rises slightly after ovulation and stays elevated until your next period. By charting your BBT daily, you can confirm that ovulation happened. The catch: BBT confirms ovulation after the fact, so it's most useful over multiple cycles to predict future patterns.

You can take your BBT with a regular thermometer each morning before getting up. Or you can use a wearable like Tempdrop or the Apple Watch temperature sensor, which track automatically overnight.

LH (Ovulation) Test Tracking

Luteinizing hormone surges shortly before ovulation, typically within a day or two. Ovulation predictor kits (OPKs) detect this surge in your urine. Some apps let you log OPK results manually. Others, like Premom, let you photograph the test strip and analyze the result.

Cervical Mucus Monitoring

Your cervical mucus changes throughout your cycle. Around ovulation, it becomes clear, stretchy, and "egg-white" in consistency. Tracking this gives you a real-time sign that ovulation is approaching (unlike BBT, which confirms it after).

Why track more than one fertility sign?

Each sign tells you something different: BBT confirms ovulation after the fact, LH tests flag the surge just before it, and cervical mucus changes show the fertile phase building. Fertility awareness approaches (often called the symptothermal method) combine them, so you are not leaning on a single signal. Look for an app that supports at least two of these.

For an FDA-Cleared Option: Natural Cycles

Best if you want: A temperature-based app that is FDA-cleared (De Novo DEN170052) for both preventing and planning a pregnancy.

Key Features

• FDA De Novo grant (August 2018) for women 18+ to monitor fertility, usable for contraception or planning a pregnancy (FDA decision summary)

• Plan Pregnancy mode that tracks ovulation and peak fertility from your temperature

Strengths

• FDA-cleared as a contraceptive and for conception planning. Natural Cycles reports 93% effectiveness with typical use as birth control (its App Store listing), and the FDA decision summary lists a typical-use Pearl Index of 6.5. That is contraception data, not a measure of how well the app finds your fertile window for conception
• Wearable support (Oura Ring, Apple Watch and others) can replace the morning oral thermometer
• Clean, modern interface that's easy to use
• Cross-platform (iOS and Android)

Limitations

• Subscription required: the App Store lists Annual at $149.99 and Monthly at $21.99 (as of October 2026)
• Takes 1-3 cycles to learn your pattern. Early predictions may be less accurate
• The algorithm is temperature-based rather than built on cervical mucus or LH tests
• No nutrition, fitness, mood, or broader health tracking
• No free tier for fertility features

Who Should Choose This

• You want an FDA-cleared option
• You're comfortable with a subscription
• You already own an Oura Ring or Apple Watch
• You want to use the same app for both TTC and, later, birth control (Natural Cycles is cleared for both)

Pricing: As of October 2026, the App Store lists Annual at $149.99 and Monthly at $21.99. The listing says the annual subscription comes with a free NC° Band. It is rated 4.8/5 from about 30K App Store ratings.

How do the 8 fertility apps compare on features and price?

The clearest differences are cost and regulatory status. Natural Cycles is subscription-only at $21.99 a month or $149.99 a year and carries an FDA De Novo authorization (DEN170052), whose decision summary reports a typical-use Pearl Index of 6.5. Most others are free to download with optional paid tiers. Here's how all 8 apps compare on features that matter for trying to conceive. Cells reflect each app's App Store listing as of October 2026; "Not listed" means the listing doesn't mention the feature, so confirm in the app.

Which fertility app should you choose?

Pick by what you will actually log every day. Choose Natural Cycles for an FDA-authorized, temperature-based method, Fertility Friend for detailed charting, Premom for scanning LH strips, Clue for a Berlin-based, GDPR-governed app, Ovia for a free option, and Veya if you want fertility data next to nutrition, mood and wearable data. Here's the bottom line for each app:

---

Do you need a hardware fertility monitor too?

A monitor is optional. Apps estimate your fertile window from what you log, while at-home monitors add measured values from urine or temperature, at extra cost. Mira and Inito read hormones such as LH and estrogen metabolites, Tempdrop measures overnight temperature, and each pairs with an app. The sections below list what each device measures, per its maker.

---

Which fertility apps integrate with wearables?

Natural Cycles lists NC Band, Oura (Gen 3 and later, with a Natural Cycles membership), Apple Watch Series 8 and later, and Garmin, per its FAQ; Veya pulls temperature from Apple Watch, Oura and Garmin; Clue and Fertility Friend list wearable or Apple Health sync on their App Store pages. For wearable-first comparisons see Natural Cycles vs Oura and Oura vs Apple Watch vs Natural Cycles. If you already own an Apple Watch, Oura Ring, or Garmin, wearable integration should weigh heavily in your choice. Overnight skin-temperature data can replace the 5am oral thermometer, and it captures readings even when your schedule is irregular. Here's where each app stands:

If you're choosing a wearable specifically to support fertility tracking, our guide to cycle tracking with wearables explains what the temperature and HRV data from each device actually mean — and which devices pair with which apps.

How do these fertility apps handle your data?

Privacy records differ sharply. Premom agreed to a 2023 FTC and state settlement ($100,000 plus $100,000) over sharing health data, Glow settled with the California Attorney General for $250,000 in 2020, Flo has a 2021 FTC order and a $59.5 million class settlement with a hearing on October 29, 2026, and Fertility Friend's listing says it does not sell or share data. Here's how each app handles it:

• Clue is headquartered in Berlin, and its App Store listing says your data is protected by strict European privacy law (GDPR).
• Natural Cycles is published by NaturalCycles Nordic AB, per its App Store listing. Read its privacy policy for how your data is used.
• Veya states "No ads. No selling your data." in its App Store listing.
• Fertility Friend's App Store listing says it does not sell or share your data or display ads.
• Premom: in May 2023 the FTC and Justice Department announced a proposed order alleging it shared health data with AppsFlyer, Google and two China-based firms; it bars sharing health data for advertising and requires Premom to seek deletion of data already shared (FTC).
• Glow agreed to a $250,000 settlement with the California Attorney General in September 2020 over alleged failures to safeguard health information, including a password-reset flaw. Read its current privacy policy before logging sensitive information.
• Flo: the FTC finalized an order in 2021 over alleged sharing of health data with outside analytics firms including Facebook and Google. In the separate class action, $59.5 million in proposed settlements with Flo, Google and Flurry received preliminary approval in April 2026, with the final approval hearing on October 29, 2026 (class counsel). Flo has since added Anonymous Mode.
• Ovia is part of Labcorp (the App Store listing reads "Ovia Health by Labcorp"). Some people are wary of a medical testing company owning a fertility app, so read its privacy policy.

How do you get started with fertility tracking?

Start by logging period dates, add a second fertility sign such as BBT or LH tests, and give the app a few cycles before judging its predictions. Predictions settle as the app collects your own history, which is why consistency matters more than which app you pick. Here are some tips to make fertility tracking actually useful:

1. Start with the basics. Log your period start and end dates. Add BBT if you can. Even basic data gives you a baseline.
2. Use at least two methods. BBT alone confirms ovulation after the fact. LH tests flag it a day or two ahead. Cervical mucus gives real-time clues. Combining two or more gives you a fuller picture.
3. Give it a few cycles. Most apps need a few months of data before predictions settle down. Don't judge an app after one cycle.
4. Track at the same time daily. BBT is most useful when taken at the same time each morning, before getting out of bed. A wearable sensor removes this requirement.
5. Don't obsess over the numbers. Fertility tracking should reduce stress, not add to it. If checking the app 10 times a day is making you anxious, scale back to once a day.
6. Bring your data to appointments. If you've been trying for a while and see a fertility specialist, your tracked data (BBT charts, cycle length history, LH patterns) gives them real information to work with instead of estimates.

Frequently Asked Questions

When is my fertile window, and can an app find it?

ACOG's fertility awareness guidance says sperm can survive up to five days while an egg lasts about 24 hours, and a study of 221 women found conception only in the six days ending on ovulation day. Apps estimate that window from logged periods, BBT, LH tests and mucus, so predictions improve as you add signs. See our ovulation tracker comparison for how each app detects ovulation.

What is the most accurate fertility tracking app?

Accuracy depends on the signs you log, not just the app, and no app is accurate for everyone. Natural Cycles is FDA-cleared (De Novo DEN170052) for both contraception and conception, and Clue describes Clue Conceive as a medical device feature in its App Store listing. Apps that let you log BBT, LH tests, and cervical mucus tend to give a fuller picture than calendar math alone, and a wearable thermometer or hormone monitor adds measured data.

Do I need a BBT thermometer to use a fertility app?

You don't need one, but it helps a lot. BBT charting confirms ovulation by showing a sustained temperature rise. Without it, most apps rely on calendar predictions, which can be off by several days. You can use a regular BBT thermometer, a wearable like Tempdrop, or the Apple Watch temperature sensor with a compatible app.

What is the best free fertility tracking app?

Several apps offer strong free features. Fertility Friend's core charting is free, with a 30-day trial of premium features. Veya includes free ovulation tracking, BBT charting, LH logging, nutrition, and wearable integration. Ovia Fertility is fully free with no premium tier at all, though it's owned by Labcorp. Basic Clue tracking is free, while advanced predictions and deeper analysis are part of Clue Plus.

How long should I track before trying to conceive?

You don't need to track for a set period before you start trying. Many people log a few cycles to learn their typical ovulation timing and luteal phase length, and tracking gives you better timing data as you go. Even one cycle of BBT charting and LH testing can show you something about your pattern.

Can fertility apps help with irregular cycles?

Yes, but symptom-based tracking matters more than predictions. Calendar-based apps struggle with irregular cycles because they assume regularity. Focus on apps that let you log LH tests, BBT, and cervical mucus so you detect ovulation in real time. Fertility Friend and Veya are built around your logged data rather than calendar assumptions.

What's the difference between a fertility app and a period tracker?

Period trackers predict when your next period will come. Fertility apps go further by identifying your fertile window, the few days each cycle when conception is possible. They typically include ovulation detection through BBT, LH testing, and cervical mucus tracking. Some period trackers (Flo, Clue) offer fertility modes, but dedicated fertility apps often provide more detailed charting and analysis.

Which fertility apps work with LH test strips (OPKs)?

Premom's App Store listing describes scanning your ovulation test and quantifying your LH levels, which makes it a natural pick if you test daily with Easy@Home strips. Veya, Fertility Friend, Clue, and Flo support logging LH results manually alongside your other fertility signs; Glow, Natural Cycles and Ovia don't name LH logging in their listings, so check in the app.

What's the best fertility app if you're doing IVF or fertility treatment?

The apps in this guide are built around natural-cycle signs: BBT, LH surges, and cervical mucus. Medicated and IVF cycles are a different job — you need medication schedules, appointment tracking, and treatment-cycle logging instead of ovulation prediction. We compared the apps built for that in our best IVF tracking app guide.

What is a fertility awareness method (FAM) app?

A FAM (or symptothermal) app supports tracking all three fertility signs together: basal body temperature, cervical mucus, and LH tests. Fertility Friend has an extensive educational library that teaches you to read your own charts. Veya logs all three signs and pulls temperature from a wearable. Natural Cycles is temperature-led and FDA-cleared.

So which fertility app should you pick?

The right fertility app depends on where you are in your TTC process and what kind of data matters most to you. If you want an FDA-cleared option, look at Natural Cycles (De Novo DEN170052); Clue also describes Clue Conceive as a medical device feature. If you want to become fluent in BBT charting and the fertility awareness method, Fertility Friend has 25 years in the category. If privacy is a priority, Clue is worth a close look.

If you want your partner involved, Glow, Premom, Natural Cycles and Flo all list partner features. If you want a free option, Ovia lists no in-app purchases. If you already track in Flo, just switch to TTC mode. If you use OPK strips daily, Premom's scanner is helpful. And if you want fertility data alongside nutrition, fitness, mood, and wearable data, Veya connects them in a single app.

What matters most is picking one and using it consistently. Fertility tracking gets more useful with every cycle of data. The app you use every day is better than the "perfect" app you forget to open.
