Flo Alternatives 2026: 7 Period Trackers Compared

Why People Are Looking for Flo Alternatives

The short version: in August 2025, a California jury found Meta liable under the California Invasion of Privacy Act for receiving Flo users' health data, and the headlines sent many users to re-evaluate. The data sharing at issue happened between roughly 2016 and 2019 and ended in 2019, and Flo has changed a lot since then. Here's the fuller picture.

Between roughly 2016 and 2019, Flo shared user health data with companies including Meta through third-party software kits built into the app. That practice ended in 2019. In 2021, Flo settled a related matter with the FTC. The lawsuits kept moving, though, and in August 2025 a jury found Meta liable for its role in receiving that data. Flo itself settled with the plaintiffs before the verdict.

After the verdict, Consumer Reports published guidance for users who wanted to delete their Flo data, and searches for alternatives went up. That's the moment this article exists for. Not because Flo is doing something wrong today, but because a news cycle like that is a natural prompt to check whether your app still fits you.

It's worth saying clearly: Flo responded to its 2021 settlement with real changes. In 2022 it launched Anonymous Mode, which lets you use the app without attaching your name or email, and it later open-sourced that work. Flo remains the most-used period tracker, with one of the largest feature sets in the category. 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 Staying With Flo Makes Sense

Staying put is a legitimate option, and for many users it's the best one. The practices behind the headlines ended in 2019, and the app you'd be leaving today is genuinely good at what it does. Here's where Flo earns a real recommendation.

• You use the community. Flo's Secret Chats connect you with millions of other users. No alternative in this guide comes close on community size, and if a 2am "is this normal?" thread has ever helped you, that's worth weighing.
• You read the content. Flo has thousands of articles written and reviewed by medical professionals. It's one of the largest health content libraries in any tracking app.
• You like how it feels. Flo's day-to-day experience is polished. Logging is quick, the design is clear, and the app rarely gets in your way. That's harder to find than it sounds.
• Anonymous Mode addresses the core worry. If your concern is your identity being attached to your health data, Flo built a mode in 2022 specifically for that. You can keep the app and drop the name.
• You're pregnant or planning to be. Flo's pregnancy mode is included in the free tier and tracks weekly development with educational content.
• You're not all-Apple. Flo runs on iOS, Android, and Apple Watch. Several alternatives below are iPhone-only or have no watch app.

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 Go Go Gaia.

What to 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. No single alternative does all four as completely as Flo does, so the right pick depends on which job 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.

The 6 Alternatives Compared

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.

For a Design You'll Want to Open: Stardust

Best if you want: A tracker with personality. Stardust pairs cycle tracking with daily hormone explanations and a visual style that's made it popular with Gen Z.

Key Features

• Cycle tracking with a daily readout of where you are hormonally and what that can feel like

• One of the few apps people describe as fun to check every day
• Free core experience

• Requires an account, with no local-only option

Who Should Choose This

For Local-Only Storage From a Nonprofit: Euki

• No account, email, or name required to use 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, Go Go Gaia, so factor that in as you read.

Key Features

• Cycle predictions and symptom tracking alongside mood, sleep, fitness, and nutrition logs

• 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

• 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

• You wear an Apple Watch, Oura, Garmin, or WHOOP

How to Move On: Exporting and Deleting 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. Flo lets you delete your account and request deletion of your data from the app's settings, and deletion is permanent, so the export comes first. Here's the practical sequence.

1. Request a copy of your data. Flo's privacy policy allows you to request your personal 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 doesn't cancel 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 request data deletion. Both live in Flo's settings. Consumer Reports published step-by-step guidance on this after the August 2025 verdict, if you want a detailed walkthrough.

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 for a polished mainstream tracker with predictions and science-backed content. Stardust covers the daily-engagement side with a design younger users like. Apple Health handles basic period logging for free on iPhone. Euki and Drip keep everything on your phone with no account. Go Go Gaia tracks your cycle alongside mood, sleep, nutrition, and labs. None of them match Flo's community size.

Is Flo safe to use now?

The data sharing behind the August 2025 verdict happened between roughly 2016 and 2019 and ended in 2019. Since then, Flo settled a related FTC matter in 2021 and launched Anonymous Mode in 2022, which lets you use the app without your name or email. The verdict concerned past practices, not what the app does today, so it comes down to your own comfort level with the company's history and current policy.

How do I delete my Flo data?

Flo lets you delete your account and request deletion of your data from the app's settings. Before you do, request a copy of your data if you want to keep your cycle history, because deletion is permanent. Also note that deleting your account doesn't 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 alerts, and retrospective ovulation estimates if you have a newer Apple Watch, all free with strong default privacy. It doesn't have Flo's community, content library, or pregnancy mode, so it suits people who mainly want simple logging.

Which period trackers keep data only on your phone?

Euki and Drip both store your data locally on your device with no account required. Euki is run by a nonprofit, and Drip is open source, so anyone can inspect its code. Apple Health is close: data lives on your device, and iCloud copies are end-to-end encrypted when two-factor authentication is on. The trade-off with local-only apps is that there's no cloud backup, so losing your phone means losing your data.

Final Thoughts

The 2025 verdict was about practices that ended in 2019, and Flo today is a different company with a genuinely useful app. 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 to never leave your device? Euki and Drip do exactly that, each in its own way. And if your reason for restlessness was wanting the cycle connected to sleep, mood, food, and labs, that's the gap Go Go Gaia 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.
