Best Fertility Apps in 2026: 8 Apps Compared

Flo is the most complete all-rounder in this list, covering period tracking, ovulation predictions, pregnancy modes and perimenopause support in one app. Daily tips and health content help users learn fertility signals, and the interface stays friendly for beginners. For most people starting with a fertility tracker app, Flo is the easiest first download.

The honest caveats matter. Premium adds the deeper tools, and Flo's past data practices drew a regulatory order, so privacy-minded users should read the current policy and settings before logging sensitive data. If privacy is your top concern, Clue below may fit better. For breadth and ease, Flo still leads.

Clue, built in Berlin, takes a science-first approach to cycle tracking, with a wide range of symptoms and cycle phases to log. Its privacy stance is a real selling point in this category: Clue states it does not sell user data, which matters when the data is this personal. The interface stays calm and readable, even for long-term tracking.

Clue Plus, at about $39.99 per year, adds deeper analysis and advanced predictions, while the free tier covers basic tracking well. Users trying to conceive may miss the TTC community features of Premom or Glow. For the best fertility tracker app that pairs solid predictions with a careful privacy approach, Clue is our pick.

Ovia Fertility approaches trying to conceive like a guided program, with a daily fertility score, personalized tips and content reviewed by clinicians. It tracks basal body temperature, cervical fluid, medications and more, and it folds in sleep, activity and nutrition data for a fuller picture. For individuals, the app is free, which is rare at this depth.

The business model deserves attention: Ovia Health, a Labcorp company, works with employers and health plans, so users should read the privacy policy and understand what data is shared and how. If that model concerns you, a paid app with a simpler model may fit better. For free, guided TTC tracking, Ovia is strong.

Natural Cycles stands apart because it is cleared by regulators as a contraceptive method when used as directed, based on basal body temperature data. That clearance reflects a specific algorithm and strict usage rules, not a general promise, and typical-use effectiveness is lower than perfect use. Users trying to conceive can also use it to spot fertile days from temperature shifts.

The price is the highest in this list, at about $149.99 per year, with no free tier. It also demands consistent morning temperature readings, which does not suit everyone. For users who want a temperature-based method with regulatory clearance, Natural Cycles is the only app here in that category, and it should be used exactly as directed.

Premom is the best app to get pregnant for users who rely on ovulation predictor kits. Its standout feature scans test strips with the phone camera and reads the result, removing guesswork from faint lines. Combined with temperature and symptom logging, it gives a clear picture of the fertile window for people actively trying to conceive.

The community forums add support during what can be a stressful process, though forum advice should never replace medical guidance. Premium pricing varies across app store listings, so check the current price before paying, and remember that test strips cost extra. For strip-based tracking, no other app here matches Premom.

Glow organizes itself around trying to conceive, with community forums, partner sharing and detailed logging of ovulation signals. Users can track LH tests, basal body temperature and cervical mucus in one chart, and companion apps cover pregnancy and baby stages. That full journey support suits couples planning over months.

The free tier includes ads and upsells, and Glow's privacy history includes a past regulatory settlement, so read the current policy before logging sensitive data. Community content is user-generated, so treat medical claims there with care. For community support plus detailed TTC tracking, Glow remains a popular choice.

Fertility Friend is the veteran of this category, online since 1998, and its charting depth shows that history. Temperature interpretation, chart overlays and community chart galleries help serious charters compare patterns across cycles. For users who chart basal body temperature, cervical fluid and ovulation tests together, no app here interprets that data with more experience.

Newcomers may bounce off the dense interface, and the design looks old beside modern rivals. The free tier is genuinely useful, with VIP membership adding advanced analysis at about $9.99 per month. If you want the best fertility tracking app for serious charting rather than a pretty dashboard, Fertility Friend leads.

Kindara serves users who practice fertility awareness methods and want full control over their charts. It supports customizable data types, including temperature, cervical fluid, moods and custom fields, and its community connects charters learning the same methods. That flexibility suits users who know what they want to track and why.

Beginners may find less guidance than in Flo or Ovia, and the smaller community means fewer shared resources. Premium costs about $4.99 per month, with a free tier for basic charting. For fertility awareness charting with deep customization, Kindara is the best ovulation tracking app of its kind in this list.
