When it comes to tracking your menstrual cycle, it can sometimes feel like you’re forced to choose between convenience, accuracy, and privacy. Over the last few years, period tracker apps have evolved dramatically, and in 2025, the best period tracker app does more than just count the days between periods. They aim to help people understand their hormones, mood swings, fertility, and overall health. But while the tech has improved, so have the questions we need to ask—especially around data privacy and medical accuracy.
In this article, we’ve explored which apps actually deliver on their promises. We’ve prioritised those recommended by medical professionals, praised by real users, and developed by teams with a clear commitment to protecting your data.
Choosing the best period tracker app can feel overwhelming, especially with the App Store flooded with pink icons and vague promises. What actually matters is a bit more nuanced.
Firstly, accuracy. Apps that use your historical data, symptoms, and hormonal cues to predict your next period or ovulation are far more useful than simple date-counting calendars. The best apps combine AI with science-backed models, and some even consult medical advisors to improve their predictions.
Secondly, data privacy. After the overturning of Roe v. Wade in the US and increasing scrutiny of health data privacy, many users are understandably cautious. Several apps have come under fire for sharing sensitive data with third parties. When choosing the best period tracker app, always read the privacy policy. Better yet, choose one that complies with strict GDPR standards, like Bearable.
Finally, usability and design matter more than people think. If it’s not easy to log symptoms or interpret the trends, you’re unlikely to stick with it. Apps like Flo and Stardust have clearly invested in UI/UX, offering both ease-of-use and deeper insights.
The best period tracker apps of 2025 have moved beyond basic cycle prediction. Today, users expect a blend of medical accuracy, usability, customisation, and—above all—data protection. But which features truly matter?
A well-designed period tracker app can serve as a vital tool for physical and mental health—not just a digital calendar.
While most period tracker apps focus solely on the menstrual cycle, Bearable stands out as the best period tracker app for offering a more holistic approach to health tracking. Originally designed as a symptom and mood tracker for people with chronic conditions, Bearable allows users to log everything from pain, fatigue, medication, and sleep to mood, cycle symptoms, and diet—all in one place.
This makes it especially helpful for people living with conditions like endometriosis, PCOS, PMDD, or chronic pain, where the menstrual cycle is just one piece of a much larger puzzle. Bearable is praised for its customisable interface, privacy transparency, and beautiful, user-friendly data visualisation tools. It also lets users spot correlations between their cycle and other symptoms—a feature highlighted in Choosing Therapy and praised by Reddit users navigating overlapping health concerns.
Notably, Bearable’s privacy policy states: “As a UK company, we’re not required to have to comply with US criminal subpoenas requesting disclosure of data,” offering an additional layer of protection for users in sensitive situations.
As one user on Reddit put it: “Bearable helped me finally realise how my flare-ups were syncing with my cycle. No other app gave me that level of insight.” If you’re looking for a tracker that goes beyond the basics, Bearable might be the most comprehensive best period tracker app available.
Key Features:
Clue has consistently ranked as one of the most trusted best period tracker apps, and in 2025, it still leads the pack. Developed in Berlin and compliant with the EU’s GDPR regulations, Clue is one of the few apps that doesn’t sell user data. It’s also one of the only apps that collaborates with scientists and researchers to improve its prediction models.
The app offers a clean, intuitive interface and lets you track over 30 data points—from pain and flow to emotions and sleep. While its free version is robust, Clue Plus unlocks additional features like cycle comparisons and advanced pattern analysis. On Reddit, users frequently cite Clue as the only app they trust: “They’re based in Germany and so their data is red-state safe,” wrote one commenter in r/TwoXChromosomes. It’s that level of cautious trust that keeps Clue at the top among the best period tracker apps.
Key Features:
With over 280 million downloads, Flo is by far one of the most popular best period tracker apps on the market. Its sleek interface and broad set of features—from period prediction to menopause tracking—make it appealing across age groups. It even offers chatbot-guided health Q&As and integrates with Apple Health.
However, Flo’s history isn’t spotless. In 2021, it settled with the FTC over allegations of sharing user data with third parties including Facebook and Google. Since then, it’s claimed to have reformed its practices, and recent updates show stronger privacy options. Many users continue to use it because of its powerful features—but it’s worth reviewing its current privacy policy before committing fully.
Key Features:
If you’ve ever searched for the best period tracker app that just does what it says on the tin—no weird wellness tips, no AI experiments—My Calendar is probably what you’re looking for. This app has been around for over a decade and has quietly built a loyal user base.
With features like cycle logging, medication reminders, and password protection, it’s a strong option for users who value simplicity. On Reddit, several users praised its reliability: “I’ve been using My Calendar for over 10 years and love it. It just works.” It may not be as modern-looking as Flo or Clue, but sometimes the best app is the one that doesn’t try to do too much.
Key Features:
Embody is a relatively new app that’s gaining traction in 2025 for one big reason: privacy. It stores all your data locally on your device, uses end-to-end encryption, and gives users full control over what they share (if anything).
Unlike some competitors, Embody doesn’t sell insights to advertisers or use your information to train third-party algorithms. It’s also beautifully designed, offering gentle nudges for mood tracking, period logs, and even lifestyle tips based on your cycle. For people who’ve grown wary of larger platforms, Embody offers a thoughtful alternative.
Key Features:
Stardust may not be for everyone, but if you enjoy a bit of cosmic context with your cycle tracking, this app blends astrology with cycle data in a surprisingly useful way. But behind the star charts is a privacy-forward approach that appeals to a younger, more data-conscious audience.
Founded by women and operated independently, Stardust has been praised on Reddit for its transparency and fun design. One user in r/TheGirlSurvivalGuide noted, “They don’t share your data. It’s a women-owned company and the layout is super cute.” The app lets you track symptoms, mood, and flow, and it stores most data locally. It’s not a clinical tool, but for many, it makes period tracking feel less clinical in the best way.
Key Features:
There is no one-size-fits-all best period tracker app. What works for someone trying to conceive may not work for someone managing PMDD or navigating perimenopause. But in 2025, you shouldn’t have to choose between functionality and safety. Apps like Clue and Embody prove that it’s possible to offer deep insights without compromising your privacy.
Before downloading any app, take a moment to read the privacy policy, scan Reddit for user experiences, and reflect on what features actually matter to you. Whether you want astrological context or science-based predictions, there’s a best period tracker app out there for you.
“As someone with multiple chronic and complex conditions (including EDS, PoTS, PMDD), I’ve tried a lot of different health tracking apps. I was never able to use any consistently for more than a few weeks. They were too complicated, or didn’t track what was important to me, or all of the interesting features were behind a paywall. With Bearable, I’ve been able to consistently track my health and what impacts it for months.” – Taylor, Bearable member
