Best Fertility Apps in 2026: 8 Apps Compared

Flo is the most complete all-round fertility app, with cycle and ovulation predictions, symptom logging, pregnancy mode and a large library of health articles. The free tier covers core tracking, while Premium adds detailed insights, an AI assistant and extra content. A community feature lets users discuss fertility topics, which many people find supportive during trying to conceive.

Flo faced regulatory action in the past over data sharing disclosures, so privacy-conscious users should read the current privacy policy and check data settings before logging sensitive details. Premium pricing also varies across app store listings, so confirm the current price in your store. For most users who want one app for cycle, fertility and pregnancy tracking, Flo is the easiest pick.

Clue takes a science-led approach to cycle tracking, with predictions based on logged data, pattern analysis over time and a clean, gender-inclusive interface. The company states that it does not sell user data and does not show ads, which matters for people tracking sensitive health data. A separate Clue Birth Control feature received FDA clearance, though the standard tracker itself is not birth control.

Clue logging for temperature and cervical mucus is more basic than in Fertility Friend or Natural Cycles, and some features such as pregnancy mode extras need Clue Plus. For users who want a trustworthy, privacy-focused tracker with solid predictions, Clue is the strongest choice here.

Natural Cycles uses basal body temperature to give a daily fertility status, with red days for fertile days and green days for non-fertile days. It is FDA-cleared as a contraception method, which sets it apart from general trackers, and it also offers a pregnancy planning mode for users trying to conceive. The annual plan includes a wearable band option in some listings, which helps with overnight temperature capture.

There is no free tier, and the method needs consistent temperature readings, so irregular sleep or irregular cycles can reduce accuracy. The yearly price is also higher than most rivals. For users who want a temperature-led, FDA-cleared method, Natural Cycles is the most distinct option in this list.

Glow is built for trying to conceive, with deep logging for ovulation tests, temperature, cervical mucus and symptoms, plus a large community of users in the same stage. Partner sharing lets a partner follow the fertility window, and the app family includes separate apps for pregnancy and baby tracking. That focus makes Glow feel more tailored to conception than general period trackers.

The free tier shows ads, and fuller features need a Premium subscription. Glow also faced a past privacy settlement, so users should review current data settings and sharing options. For community support plus detailed fertility logging, Glow remains a popular and practical choice.

Ovia offers free cycle, fertility and pregnancy tracking, with tools such as a kick counter and contraction timer in pregnancy mode. Some users get coaching and extra features through employer-sponsored programs, which adds human support beside the app. The interface is friendly and easy to learn for first-time trackers.

Ovia is ad-supported on the free tier, and its fertility predictions are simpler than those in Fertility Friend or Premom. Users who want deep charting or test strip analysis may outgrow it. For free, straightforward tracking that carries through pregnancy, Ovia is a solid choice.

Premom is built around ovulation predictor kits. Users photograph test strips in the app, which reads the result and charts luteinizing hormone trends over the cycle. That gives a clearer ovulation signal than calendar prediction alone, especially for users with variable cycle lengths. Core cycle tracking is free.

Test strips are an extra cost, and some advanced features need a premium subscription. Premom also focuses on ovulation rather than full cycle health content. For users already using ovulation tests, or planning to start, Premom turns strip results into a useful chart without manual guesswork.

Fertility Friend is the long-standing choice for detailed charting, with basal body temperature charts, cervical mucus logging, ovulation test results and symptom analysis in one place. The app interprets charts and highlights patterns, which helps users and clinicians review cycles together. Data can be shared or exported for appointments.

The interface looks dated beside Flo or Clue, and the most useful analysis features need a VIP subscription. New users may also need time to learn charting terms. For users who want the deepest charting and analysis, Fertility Friend remains the reference app.

Mira pairs an analyzer device with an app to measure actual hormone concentrations from urine tests, giving numeric luteinizing hormone and estrogen results rather than a simple positive or negative line. That detail helps users with irregular cycles or conditions that make standard ovulation tests hard to read. The app charts hormone trends and predicts the fertile window from those numbers.

Mira needs a device plus ongoing test wands, so total cost is higher than an app alone, and there is no free tier. Results still need clinical context, especially for users with fertility conditions. For users who want lab-style hormone data at home, Mira is the most advanced option here.
