The best Flo alternatives in 2026

Why people look for a Flo alternative

Flo is big: about 2 million ratings on the US App Store, at 4.7 stars. People leave for three reasons.

The privacy record

The FTC finalized an order against Flo Health on June 22, 2021. It alleged that Flo shared health data from millions of users with marketing and analytics firms, including Facebook and Google, despite promising to keep it private. The order requires Flo to get consent before sharing health data, have an independent review of its privacy practices, and tell affected users.

Users then sued. Google settled in July 2025 and Flo in early August, and on August 5, 2025 TechCrunch reported that a California jury found Meta violated the state's privacy law by collecting Flo users' data.

Flo's privacy FAQ now says it has never sold user data, and Anonymous Mode lets you use the app with no name or email attached. The App Store label still lists purchases, location, identifiers and usage data under "Data Used to Track You".

What sits behind Premium

Flo Premium holds the daily tailored insights, the Symptom Checker, fertility insights for trying to conceive, the 24/7 Health Assistant and the in-depth pregnancy features. The listing shows Premium prices from $1.99 to $59.99.

Cycles that change

Flo has a Perimenopause Score and a Menopause Timeline. Women in their 40s often want hot flashes, night sweats, sleep and doctor visits at the center of the app instead of a fertility calendar.

How we picked these Flo alternatives

We didn't score or star anything. For each app we read its US App Store listing, its Google Play listing where there is one, and the company's own privacy and help pages, and compared what someone leaving Flo asks about:

• The real price. What the free tier keeps, and what moves to a subscription.
• Data practices. The App Store label under "Data Used to Track You", and what the policy says about selling and sharing.
• An account. Whether you can use it without one.
• Changing cycles. Support for irregular cycles, perimenopause and menopause.
• Platforms. iPhone, Android or both.

Store privacy labels are written by the developer and Apple doesn't verify them. If something here is out of date, tell us and we'll fix it.

The six apps, one by one

1. Her Good Days: the best Flo alternative overall

Her Good Days is one free app for every stage: periods, trying to conceive, pregnancy, the months after birth, perimenopause, menopause and after. Every feature is free, there's no paid plan, and it shows no third-party ads. The app has no outside analytics or ad code, and Private mode lets you use it with no account, with your logs in an encrypted database on your phone.

Best for: anyone who wants Flo's tracking without a subscription, and anyone whose cycles are starting to change.

• Cycle. A month calendar, your cycle lengths, your next period as a range of days, and a cycle ring on Today.
• Trying to conceive. Estimated fertile days from your past cycles, labeled Not birth control, plus ovulation test results with the time you took them.
• Pregnancy. Your week and due date, appointments with your questions, a kick counter and a contraction timer, then a log for after the birth.
• Perimenopause and menopause. Hot flashes, night sweats and brain fog at the top of the Log menu, each as mild, moderate or severe, with hot flashes by week and any gap of 60 days or more between periods.
• Everything else. Sleep, mood, food with protein and fiber, medications, and video workouts led by a trainer.
• Doctor report. A PDF for the dates you pick, with periods, cycle lengths, symptoms, sleep and medications.

Sign in and your logs sync to a new phone; stay in Private mode and they never leave this one. Steps, sleep, weight and workouts can come in from Apple Health or Health Connect. Teen mode, for 13 to 17, has no shop, no weight-loss goals and no fertile-day features. Pricing: free. An optional shop of wellness products pays for the app.

2. Clue: the like-for-like swap

Clue covers the same ground as Flo: predictions, a long symptom list, and modes for periods, trying to conceive, pregnancy and perimenopause that you switch between (App Store, 4.8 from 407K ratings).

• Clue Plus adds deeper analysis, advanced predictions and personalized insights.
• Its privacy policy says the health data you track is never shared with or sold to advertisers. If you turn it on in settings, install and subscription events go to ad networks such as Meta and TikTok.
• The App Store label lists identifiers as used to track you.

Pricing: free tier; Clue Plus is $9.99 a month or $39.99 a year. Limit: the deeper analysis sits behind Clue Plus. More in Clue alternatives.

3. Apple Health Cycle Tracking: built into the iPhone

Already on the phone. You log periods, symptoms, spotting and temperature, get period and fertile-window predictions, and export a PDF of the last 12 months. From 40, it can tell you when your patterns suggest perimenopause, and you can set a perimenopause or menopause stage (Apple support). With two-factor authentication on, cycle data in iCloud is end-to-end encrypted. Apple says Cycle Tracking should not be used as birth control. Limit: iPhone only, with no food or workout logging inside Cycle Tracking.

4. drip: a minimal open-source tracker

drip is free and open source, and "everything you enter stays on your device" (dripapp.org). It tracks bleeding, fertility, mood, pain and other symptoms, estimates fertility with the symptothermal method, and exports your data. Its App Store label reads "Data Not Collected", and it runs on iPhone and Android. Limit: a small project, with 59 ratings on its App Store page.

5. Natural Cycles: FDA-cleared birth control

• Hormone-free birth control cleared by the FDA, based on your temperature
• Readings from a thermometer, the NC° Band, Oura, WHOOP, Garmin or an Apple Watch Series 8 or newer
• NC° Perimenopause follows temperature and symptoms through to after menopause
• $21.99 a month or $149.99 a year; core features need a plan (App Store)

It suits you if contraception is the reason you track and you'll take a reading every morning. More in Natural Cycles alternatives.

6. Stardust: cycle tracking with astrology

A cycle tracker with a moon calendar, zodiac insights and daily cards for your moon, sun and rising sign, plus pregnancy and postpartum modes (App Store). Plans run $6.99 a month or $29.99 a year, and its label lists purchases, identifiers and usage data as used to track you. In 2022 TechCrunch reported that Stardust removed an end-to-end encryption claim from its privacy policy. More in Stardust alternatives.
