The apps
Hello Phase
Best free period tracker on Android- Free, Plus $39.99 a year
- Android

Watch out for
- Hello Phase is Android only and too new to have a Google Play rating.
- The hormone chart is drawn from your own cycle length and ovulation day, so it is an estimate and never a lab reading.

Find the right app for you
Why do free period apps show ads or paywalls?
Every free app is paid for somehow. Period Calendar, GP Apps, Maya, Clover and Eve by Glow run ads. Flo, Clue and our own Hello Phase sell an optional subscription, while Ovia, Euki, Spot On and Apple Health are backed by employers and health plans, a nonprofit, Planned Parenthood or Apple, and drip is an open source project.

Which period apps moved features behind a paywall in 2025 and 2026?
These are single reviews rather than a survey, so read them as warning signs and check the app yourself.
| App | What the reviewer wrote | Where and when |
|---|---|---|
| Premom | "I no longer have access to previous cycles information" and, from another reviewer, "I can't even see my history without paying a subscription fee" | Google Play, Sep 15 and Sep 17, 2026 |
| Clue | "99% of features are paywalled" | Google Play, Sep 1, 2026 |
| Glow | "You now have to pay to do anything but log in the calendar" | Google Play, Jun 13, 2025 |
| Maya | Complained about ads and the app "taking away anything past 6 months history" | App Store, Jan 7, 2026 |
| Flo | "at the very end of a long setup process, they told me I needed to pay a subscription" | App Store, Oct 18, 2026 |
Check that the free plan keeps your full history and lets you export it. In Hello Phase the full calendar and a CSV of every logged day are free, and the pricing page lists everything Plus adds.
Can a free app track irregular periods?
Yes, but free apps handle it differently. Ovia supports irregular cycles, Apple Health warns you when six months of history look irregular, and Hello Phase shows each prediction as a date range that widens when your cycles vary. In a 2020 industry-funded study "only 12.4% of users actually had a 28-day cycle", and Hello Phase suggests seeing a doctor if your cycles are often shorter than 21 days or longer than 35.
Apps we left out and why
We could not find a full list of what stays free in Clue, and Premom reviewers say past cycles are locked behind a subscription, with the FTC proposing an order in 2023 that bars Premom from sharing health data for advertising. Glow needs an account and reached a $250,000 settlement with California's attorney general in 2020 over security weaknesses. Maya and Clover show ads, Life keeps export for Premium, Natural Cycles costs $149.99 a year and Kindara has had no App Store update since September 2021.
How to choose
On Android, start with Hello Phase for a free hormone chart, check-ins and export with no ads, or Period Calendar if ads do not bother you. On iPhone, start with Apple Health or My Cycle, and for privacy on either phone look at drip and Euki or our list of the most private period tracker apps. We also compare cycle syncing apps, PMDD trackers and the best period tracker apps overall, paid ones included.
Questions people ask
What is the best free period tracker app?
On Android the best free period tracker is Hello Phase, our own app, because logging, predictions for three cycles, daily check-ins, an estimated hormone chart, CSV and PDF export and a widget are free with no ads and no account. drip suits anyone who never wants a paid tier, and on iPhone, Cycle Tracking in Apple Health is free and already installed.
Is there a period tracker with no ads and no subscription?
Yes, drip, Euki, Ovia and Spot On have no ads and no in-app purchases in either store, and neither does My Cycle on iPhone, though Ovia needs an account and Euki has not been updated since September 2025.
Is Flo free?
Yes, its help center says the free plan covers period and ovulation predictions, 80+ symptoms, reminders, Secret Chats, Anonymous Mode and a basic Partner Mode, while daily tailored insights, expert-led videos, deeper pregnancy features and the Symptom Checker are paid.
Is Clue free?
Clue has a free version, and Clue Plus at $39.99 a year or $9.99 a month adds data visualization for pattern analysis, Clue Connect cycle sharing, unlimited custom tags and expert content. A Google Play reviewer wrote in September 2026 that "99% of features are paywalled".
Can I use a free period app as birth control?
Not on its own, because predictions from period dates can be wrong and most period trackers, Hello Phase included, are not contraceptives. Natural Cycles was the first app the FDA authorized for contraception, in August 2018, and it costs $149.99 a year in the App Store.
Can I export my data from a free period app?
Some do, so check before your history grows. Hello Phase exports every logged day as CSV and a one-page PDF summary on its free plan, Apple Health exports a 12-month PDF, and Life keeps export for Premium.
Try Hello Phase
Hello Phase is free on Android with no account and no ads.

History of updates

Hello Phase is for tracking and learning about your cycle. It is not a contraceptive and it does not diagnose medical conditions. Predictions can be wrong, so do not rely on any app here to avoid or plan a pregnancy, and talk to a clinician about symptoms that worry you.
