Flo Alternatives 2026: 7 Period Trackers Compared

Why are people looking for Flo alternatives?

The short version: in August 2025, a California jury found that Meta violated the California Invasion of Privacy Act in connection with Flo users' health data, as Consumer Reports reported, and the headlines sent many users to re-evaluate. The data sharing at issue dates from roughly 2016 to 2019, and Flo has added Anonymous Mode since. Here's the fuller picture.

In June 2021 the FTC finalized an order against Flo after alleging it shared sensitive health data from millions of users with companies including Facebook and Google despite promising privacy. The order requires affirmative consent before sharing health information and an independent privacy review (FTC). A separate class action over the same 2016 to 2019 data sharing reached a proposed $59.5M settlement with Google, Flo and Flurry (Flo's share: $8M); it received preliminary approval in April 2026, with a final approval hearing set for October 29, 2026 (court-approved notice). The settling defendants deny wrongdoing. Meta did not settle, and in August 2025 a jury found it violated California's privacy law; Meta denies the claims (Consumer Reports).

After the verdict, Consumer Reports published guidance for users who wanted to delete their Flo data. That's the moment this article exists for. Whether to switch is a personal call, and a news cycle like that is a natural prompt to check whether your app still fits you.

It's worth saying clearly: Flo has since added Anonymous Mode, which its own site describes as period tracking without identity, and its App Store listing highlights it too. That same listing cites over 570 million downloads worldwide and a 4.7-star rating from about 2 million ratings (as of October 2026). Some users read the 2025 news and stayed. Some used it as a reason to try something new. Both are sound decisions, and the rest of this guide is for the second group. For a deeper head-to-head with Flo's closest rival, see our Clue vs Flo comparison.

When does staying with Flo make sense?

Staying put is a legitimate option. Flo has added Anonymous Mode since the period at issue, and the app you'd be leaving is widely used, with 570M+ downloads per its App Store listing (as of October 2026). Here's where Flo earns a real recommendation.

• You use the community. Flo's Secret Chats, listed under Premium on its App Store listing, let you find tips from other members. None of the alternatives below is built around a comparable community, and if a 2am "is this normal?" thread has ever helped you, that's worth weighing.
• You read the content. Flo's listing describes its information as backed by health experts, with daily insights and expert-led videos in Premium. If you use that content, smaller apps may not replace it.
• You like how it feels. Its App Store rating is 4.7 stars from about 2 million ratings (as of October 2026), which suggests many people find the day-to-day experience works for them.
• Anonymous Mode addresses the core worry. If your concern is your identity being attached to your health data, Flo built Anonymous Mode for that concern. You can keep the app and drop the name.
• You're pregnant or planning to be. Flo's listing describes a Pregnancy Mode with weekly baby-development updates, with in-depth pregnancy features under Premium.
• You're not all-Apple. Flo is on iOS and Android, and its App Store listing says it works with Apple Watch. Several alternatives below are iPhone-only.

If most of that describes you, turning on Anonymous Mode and settling back in is a perfectly good outcome of reading this page. The rest of the guide is for everyone else. If you want a direct comparison with our own app first, we wrote an honest one: Flo vs Veya. And if you're weighing Flo mainly because you're trying to conceive, our Flo vs Glow comparison looks at that specific use case, since Glow leans TTC while Flo stays general-purpose.

What should you look for in apps like Flo?

Apps like Flo cover four jobs: predicting your cycle, logging symptoms, teaching you what's going on, and connecting you with other people. Different apps lean on different jobs, so the right pick depends on which one you actually open the app for. Decide that first and the list below gets much shorter.

• Predictions. Every app here predicts periods, but they differ in approach and in how much history they need. Keep your expectations realistic: prediction accuracy varies more than most people think, whichever app you use.
• Symptom depth. If you log moods, cramps, skin, and energy, check the symptom list before committing. The local-only apps keep this simple on purpose.
• Where your data lives. Cloud-based apps sync across devices and survive a lost phone. Local-only apps keep data on your device with no account at all. That's the central trade-off in this list.
• Pregnancy plans. If you might want a pregnancy mode in the next year or two, that narrows the field quickly.
• Price and platform. Three of the six alternatives are completely free. Two of the seven apps in this comparison are iPhone-only.

Which Flo alternative fits which reason for leaving?

Here are six apps matched to different reasons for leaving, in no particular order of quality. Each profile covers features, strengths, honest limitations, and price. For a broader look at the category, our six-app period tracker comparison goes deeper on the mainstream options.

If you want an app for birth control: Natural Cycles is the one to look at. The FDA granted it De Novo authorization in August 2018 as a stand-alone app for women 18 and over that can be used to prevent pregnancy or plan one (FDA letter). The FDA's decision summary reports a perfect-use Pearl Index of 1 and a typical-use Pearl Index of 6.5, roughly 6.5 pregnancies per 100 users per year (decision summary). Our Flo vs Natural Cycles comparison goes deeper. None of the other apps below is a contraceptive. Clue and Apple both say so themselves, and the same goes for Veya.

For Privacy in a Mainstream App: Clue

• A core symptom list (cramps, mood, headache, and more)

• Apple says Cycle Tracking should not be used as birth control or to diagnose

If you're comparing Flo against an ovulation-predictor-kit app instead of a general tracker, our Premom vs Flo comparison covers how Flo stacks up against Premom's OPK-strip-scanning approach.

For Local-Only Storage From a Nonprofit: Euki

Best if you want: Tracking where your data physically never leaves your phone. Euki is managed by an independent U.S. nonprofit (Euki), and its App Store listing says you don't need an account, email, or phone number.

Key Features

• Period and symptom tracking stored only on your device
• No account, email, or name required to use it
• PIN lock for the app itself
• Free to use, with no paywalls, according to its site

Strengths

• Its App Store listing says your data is stored locally on your device and nowhere else, so there's no company-held copy to share
• Nonprofit-run, and its site says it never collects users' personal data
• Free, with no in-app purchases listed

Limitations

• Predictions are simpler than the big apps, which is a deliberate design choice rather than a flaw
• No cloud backup, so a lost or broken phone means lost data
• Local-only storage means no cross-device sync

Who Should Choose This

• Local-only storage is your top requirement
• You want a tool from a nonprofit rather than a company
• You're fine trading prediction sophistication for privacy. Euki delivers exactly what it promises

Pricing: Free; the App Store listing shows no in-app purchases and points to donations through its website (as of October 2026).

For Open-Source Tracking: Drip

Best if you want: A tracker whose code anyone can read. Drip is open source and, per its App Store listing, leaves your data on your phone.

Key Features

• Period and fertility tracking you log yourself
• Data stays on your phone, and the listing says the developer collects no data from the app (self-reported)

• Import and export built in, so your data is portable
• Open-source code, published for anyone to inspect

Strengths

• You don't have to trust a privacy policy, because you (or anyone technical) can verify what the app does

• Free, with no in-app purchases listed

Limitations

• Data stays on one phone, so there's no syncing across devices
• Fewer features and simpler predictions than mainstream trackers, by design
• No community or content library

Who Should Choose This

• Open source is how you decide what software to trust
• You already take your temperature and want somewhere honest to log it

For One App Across Cycle, Mood, Sleep, and Labs

Best if you want: Your cycle tracked next to your mood, sleep, fitness, nutrition, symptoms, and lab results, with patterns drawn from your own data. This one is our app, Veya, so factor that in as you read.

Key Features

• Cycle predictions and symptom tracking alongside mood, sleep, fitness, and nutrition logs
• Correlation insights from your own data, like "cramps run worse on short-sleep days"
• Wearable data pulled in automatically via Apple Health (Apple Watch, Oura, Garmin, WHOOP)
• Lab tracking for values like TSH and AMH over time
• Pregnancy mode, with data that carries across life stages instead of starting over
• Doctor-ready data export

Strengths

• The cycle sits in the same record as everything that affects it, so patterns can show up that a cycle-only tracker doesn't have the data for
• Wearable data fills in what manual logging misses, like sleep and overnight temperature
• No ads, no data selling
• If you already log periods in Apple Health, that history syncs in when you start

Limitations

• iOS only, with no Android version
• Newer app with a much smaller community than Flo, and no in-app forums
• No editorial content library comparable to Flo's
• Some advanced features require premium

Who Should Choose This

• You kept wishing Flo could see your sleep, food, or workout data next to your cycle
• You wear an Apple Watch, Oura, Garmin, or WHOOP
• You want one record that runs from cycle tracking through pregnancy and beyond

Pricing: Free (most features), Premium $9.99/month or $49.99/year for full AI insights.

Download: Available on iOS App Store

Feature Comparison Table

Here's how Flo and the six alternatives compare on the things ex-Flo users ask about most, based on each app's own listing or support page as of October 2026. A ✅ means included, ⚠️ means partial or worth double-checking, 🔒 means premium-only, and ❌ means not available.

How do you export and delete your Flo data?

If you've decided to switch, do it in this order: get your data out, set up the new app, then delete. Per Consumer Reports, deleting or deactivating your account in the app is different from a legal deletion request, so it recommends emailing [email protected] as well. Deletion can't be undone, so the export comes first. Here's the practical sequence.

1. Ask for a copy of your data. Look in the app's settings or contact Flo support. Even if you never open the file, it preserves years of cycle history.
2. Cancel your subscription separately. If you pay for Flo Premium through the App Store or Google Play, deleting your account may not stop the billing. Cancel in your phone's subscription settings.
3. Set up the new app before deleting. Enter your last 2 or 3 period start dates by hand. That gives any tracker a working baseline immediately.
4. Delete your account and send a deletion request. Consumer Reports recommends emailing [email protected] with the email address you signed up with, and its post also points to its Permission Slip app for sending requests.

And be honest with yourself about the switching costs, because they're real. You lose the community, which no app here replaces at Flo's scale. You lose the content library. And your new app starts with a thin history, so predictions take a couple of cycles to settle in. None of that is a reason to stay if you want to go. It's just better to know before you delete than after.

Frequently Asked Questions

What apps are like Flo?

The closest apps like Flo depend on which part of Flo you used most. Clue is the nearest match in style, with predictions and a library of articles. Stardust covers daily insights, with moon and astrology features. Apple Health handles basic period logging for free on iPhone. Euki and Drip keep data on your phone. Veya tracks your cycle alongside mood, sleep, nutrition, and labs. For FDA-cleared birth control, Natural Cycles is the one to look at. None of the others is built around a community the way Flo's Secret Chats are.

Is Flo safe to use now?

That's a personal call, so here are the facts to weigh. In June 2021 the FTC finalized an order against Flo over sharing health data from millions of users with firms including Facebook and Google. A separate class action over the same 2016 to 2019 data sharing reached a proposed $59.5M settlement with Google, Flo and Flurry, with preliminary approval in April 2026 and a final approval hearing set for October 29, 2026. In August 2025 a jury found Meta violated California privacy law. Flo has since added Anonymous Mode, which lets you use the app without attaching your identity. Read Flo's current privacy policy and decide what you're comfortable with.

How do I delete my Flo data?

Consumer Reports notes that deleting or deactivating your account in the app is different from a legal deletion request, and recommends also emailing [email protected] from the address you signed up with. Before you do, ask for a copy of your data if you want to keep your cycle history, because deletion can't be undone. Deleting your account may not cancel a Flo Premium subscription billed through the App Store or Google Play, so cancel that separately in your phone's subscription settings.

Will I lose my history if I switch from Flo?

Your logs won't transfer automatically, so export a copy from Flo first if you want to keep them. In the new app, you can enter your last few period start dates by hand to give it a head start. Most trackers need about 2 cycles of fresh logging to calibrate their predictions to you.

Is Apple Health cycle tracking enough to replace Flo?

It depends on what you used Flo for. Apple Health covers period logging, a basic symptom list, cycle deviation notifications, and retrospective ovulation estimates if you have an Apple Watch Series 8 or later or an Apple Watch Ultra, all free. Apple says Cycle Tracking data synced to iCloud is end-to-end encrypted when two-factor authentication is on. It doesn't have Flo's community or content library, so it suits people who mainly want simple logging.

Which period trackers keep data only on your phone?

Euki's App Store listing says your data is stored locally on your device and nowhere else, and Drip's says it leaves your data on your phone. Euki is run by a nonprofit, and Drip is open source, so anyone can inspect its code. Apple Health isn't local-only, but cycle data synced to iCloud is end-to-end encrypted when two-factor authentication is on. The trade-off with local-only apps is no cross-device sync, so losing your phone can mean losing your data.

Final Thoughts

The 2025 verdict concerned data sharing from 2016 to 2019, and Flo has added Anonymous Mode since. It remains a widely used app, with 570M+ downloads per its App Store listing. If the community and content are why you open it, staying (with Anonymous Mode on, if that helps) is a fine answer.

If you're moving, match the app to your actual reason. Privacy-minded but want the familiar experience? Clue is the natural landing spot. Want tracking to feel less like a chore? Stardust. Want to simplify down to the basics? Apple Health is already on your phone. Want your data kept on your device? Euki and Drip are built for that, each in its own way. Want FDA-cleared birth control? Natural Cycles is the one to look at. And if your reason for restlessness was wanting the cycle connected to sleep, mood, food, and labs, that's the gap Veya was built for.

Still deciding? Pick one and log for 2 cycles. That's enough to know if it fits, and you can always switch back.

One more note if you landed here by mistake: if you're actually trying to replace Premom rather than Flo, our Premom alternatives roundup is the more direct fit.
