Let's get one thing straight. Most period apps are a digital dumpster fire. They’re bloated with pastel flowers, patronizing tips, and a shady business model that treats your intimate health data like a commodity to be auctioned off to the highest bidder. You deserve better than a pink, fluffy app that asks if you’re feeling “emotional” while selling your ovulation patterns to data brokers.
This is your brutally honest guide to finding the best free period tracker that actually respects your intelligence and your privacy. Forget the cutesy euphemisms and toxic positivity. We're diving into the tools that put you in control, not the ones that try to ‘fix’ your beautifully chaotic cycle.
In this list, you'll get a no-bullshit breakdown of the top contenders. We’ll analyze their features, scrutinize their privacy policies like a scorned lover going through phone records, and show you exactly how they function with real screenshots. This isn't about finding a tracker to manage your 'problem'. It's about arming yourself with a digital ally that works for you, keeps your secrets safe, and helps you reclaim the power in your own blood. No fluff, no shame, just the forbidden truths.
1 Bloody Mary
In a market flooded with condescending, floral apps that treat your data like a product, Bloody Mary is the brutally honest best friend you’ve been waiting for. It’s the best free period tracker for anyone who values privacy and a no-nonsense approach to their cycle. It rejects the fluff, offering a clean, intuitive interface that lets you log your bleed and get back to your life.
Our entire philosophy is built on absolute privacy. Your data stays on your device. Period. (no pun intended). It’s never uploaded to a cloud, sold to advertisers, or used to target you with fertility ads. This on-device storage model is a massive middle finger to the data-hungry tech world. Bloody Mary delivers reliable, algorithm-based predictions without ever compromising your secrets.
Why We're Our Top Pick
Bloody Mary (BM) excels by focusing on what actually matters: accurate tracking, user privacy, and honesty. It’s particularly effective for those of us with gloriously unpredictable cycles, PCOS, or endometriosis, because BM's predictions adapt without making you feel like your body is "broken." For a deeper dive into this, check out our take on why irregular cycles are actually normal on our blog.
Our app injects a dose of deadpan humor into the reminders, which feels less like a clinical notification but it's more like a text from a confidante who just gets it. We're trying our best to bring something new to the market.
Best For: Privacy purists, those with irregular cycles, and anyone fed up with patronizing, pink-washed apps.
Key Strength: Uncompromising privacy with 100% on-device data storage. Your secrets are safe.
Availability: Free on both iOS and Android with permium feaures for those who want a little more from their period tracker.
Pros:
Privacy-First: Your data is yours alone. It never leaves your device.
Clean Interface: No ads, no pink clutter, no bullshit.
Realistic Predictions: Adapts to your chaotic cycle without judgment.
Irreverent Tone: Reminders that don't sound like they were written by a robot in a flower crown.
Cons:
No Cloud Backup: Data is stored locally, so if you chuck your phone into a volcano, your cycle history goes with it unless you've made a manual backup.
(Intentionally) Limited Advanced Features: Lacks some of the obsessive charting found in more data-heavy apps. It's a tracker, not a science project.
2 Apple Health – Cycle Tracking
For those already living in the walled garden of Apple, the best free period tracker might already be on your phone. Apple Health’s built-in Cycle Tracking is the no-nonsense, privacy-first option for anyone who’s tired of downloading yet another app that wants to sell their data or show them ads for tampons. It does the basics, and it does them well, without the frilly, pink nonsense.
You can log your period, flow, and symptoms right inside the Health app you probably ignore. It syncs with your Apple Watch, letting you log a surprise bleed from your wrist without having to dig for your phone. The predictions are solid, and it will even flag potentially irregular cycles without making a big deal about it.
Why It’s a Contender
Its biggest selling point is privacy. Your cycle data stays on your device, encrypted and away from prying eyes. There’s no separate signup, no "community" forum, and zero ads. It’s ideal for the minimalist who wants a clean, integrated tool that just works. However, it’s obviously useless if you’re on Android. Still, for a free, secure, and blessedly quiet tracker, it’s a powerful choice.
Access: Free and pre-installed on iPhone and Apple Watch.
Best For: Apple users who prioritize privacy and want a simple, ad-free experience.
Heads-Up: Android users are out of luck. Obviously.
3 Fitbit app – Menstrual Health Tracking
If you’re already tracking every step, heartbeat, and REM cycle, integrating your period data into the Fitbit app makes a lot of sense. The Menstrual Health Tracking feature lives inside the app you already have, turning your Fitbit into a more holistic health dashboard. It’s a solid, straightforward tool for anyone who wants to see how their cycle impacts their sleep and activity, without needing a separate app.
You don’t even need a Fitbit device to use it; the app is free to download and use for tracking on both iOS and Android. It lets you log your period, symptoms, and moods, and predicts your fertile window and ovulation day based on the data you provide. It’s less about community forums and more about seeing your personal health data in one place.
Why It’s a Contender
The biggest perk is convenience for existing health trackers. Seeing your period symptoms alongside your sleep quality or workout intensity can be genuinely insightful. It’s a practical, no-frills option that’s blessedly free of pink butterflies and cutesy notifications. However, it’s owned by Google, so your comfort with their data practices is a factor. Still, as a free period tracker that consolidates your health stats, it’s a strong and logical choice for many.
Access: Free on both iOS and Android, works with or without a Fitbit device.
Best For: Health data enthusiasts who want their cycle info integrated with their fitness stats.
Heads-Up: Owned by Google. Read the privacy policy and decide for yourself.
4 Samsung Health – Cycle Tracking
For the Android crowd, particularly those loyal to Samsung, your best free period tracker might be the one you've been ignoring. Samsung Health's built-in Cycle Tracking is the no-fuss, ad-free alternative for anyone who refuses to download another app that wants to sell their data or serve them fertility clinic ads. It handles the essentials with a clean interface and zero pink fluff.
You can log your period, symptoms, and moods directly within the Samsung Health app that came with your phone. The predictions are solid, and it offers calendar views to map out your fertile window and estimated period dates. Like its Apple counterpart, it integrates with wearables like the Galaxy Watch, but you don't need one to get the core tracking features. It just sits there, quietly doing its job.
Why It’s a Contender
Its primary advantage is convenience and its ad-free experience for Samsung users. The data is stored within your Samsung account, offering a more private option than many third-party apps that treat your cycle data like a commodity. There’s no separate signup or "community" to navigate. It's built for the minimalist who wants a reliable tool that integrates seamlessly with their device. Of course, the experience is best on a Samsung phone.
Access: Free and pre-installed on most modern Samsung devices.
Best For: Samsung users wanting a private, integrated, and ad-free tracker.
Heads-Up: Optimized for the Samsung ecosystem; non-Samsung Android users may have a different or unavailable experience.
5 Clue – Period & Ovulation Tracker
Clue feels like the grown-up in the room of period trackers. It’s science-backed, gender-neutral, and has built its reputation on a straightforward promise: they don’t sell your health data. For anyone tired of flowery, pink-washed apps, Clue offers a clean, almost clinical interface that focuses on data over decoration, making it one of the most trusted names in the game.
The free version gives you the core essentials you need: reliable period predictions, ovulation tracking, and a place to log symptoms without being bombarded by ads. It’s a solid, no-frills option that does the job without trying to be your best friend or sell you fertility tea. The app feels robust, and its commitment to contributing to scientific research (with user consent) adds a layer of credibility that most competitors lack.
Why It’s a Contender
Clue’s biggest draw is its transparent, privacy-forward stance combined with multi-platform availability. It’s one of the best free period tracker options for those who want a dedicated, trustworthy app that isn’t tied to a specific phone brand. While its most powerful features are locked behind a paywall, the free version is more than capable for everyday tracking. It’s an OK choice for anyone who values data integrity as much as accurate predictions.
Access: Free with an optional paid subscription (Clue Plus). Available on iOS and Android.
Best For: Data-driven users who want a science-backed, privacy-focused app that works on any device.
Heads-Up: The truly deep insights require opening your wallet for a subscription.
6 Flo – Cycle & Period Tracker
Flo is the heavyweight champion of the period tracking world, a powerhouse app with millions of users and a feature list as long as your arm. Its free version is surprisingly robust, offering period and ovulation predictions and a library of over 80 symptoms you can log. It positions itself as a comprehensive women's health partner, not just a period counter.
The app uses its massive dataset to inform its predictions, though it's crucial to remember that period prediction accuracy is not magic and is only as good as the data you give it. Flo’s interface is slick, and the sheer volume of health metrics you can track is impressive. The paid tier unlocks educational content, but the core tracking is free.
Why It’s a Contender
For many, Flo is the best free period tracker because its feature set is so extensive without hitting a paywall. However, its history with data privacy is complicated. The company got its hand caught in the cookie jar for sharing user data with third parties like Facebook, a serious red flag. While they’ve since introduced an "Anonymous Mode" and beefed up their privacy policies, the past leaves a shadow. It’s a powerful tool, but one that requires you to do your homework and decide if the trade-off is worth it.
Access: Free on iOS and Android; Premium subscription available.
Best For: Users who want a feature-rich tracker and are willing to carefully manage their privacy settings.
Heads-Up: Has a documented history of privacy issues. Proceed with caution and read their latest policy with the skepticism of a jaded detective.
7 Glow (and Eve by Glow) – Women’s Health Suite
Glow positions itself not just as a period tracker but as an entire reproductive health ecosystem. Its suite of apps covers everything from your first period to your first baby, making it a one-stop-shop for those planning for or navigating fertility and parenthood. The core free period tracker in its apps, Glow and Eve, offers detailed logging for symptoms, moods, and sex life, all wrapped in a community-focused interface.
This is the app for the person who wants company on their journey. It offers robust tools for those trying to conceive, including partner syncing and extensive fertility charting. The main draw is its massive, active community where users can anonymously ask questions and share stories. If you want a forum along with your forecast, this is where you’ll find it.
Why It’s a Contender
The appeal is its all-in-one approach. You can graduate from period tracking in Eve to fertility tracking in Glow, then to pregnancy and baby tracking with their other apps. However, this social-first approach comes with a major caveat: privacy. The company settled a major case in 2020 regarding data security flaws. While they've updated policies, it’s a history worth knowing. It’s a powerful tool, but one that demands you read the fine print before sharing your intimate data with the class.
Access: Free with a Premium subscription for advanced features. Available on iOS and Android.
Best For: Users actively trying to conceive who want community support and integrated fertility tools.
Heads-Up: Had significant, publicly settled privacy issues in the past; scrutinize the current privacy policy.
8 Planned Parenthood – Spot On
If you’re looking for a period tracker backed by actual sexual health experts instead of a tech company, Spot On is your answer. Developed by Planned Parenthood, this app is less about frilly aesthetics and more about providing reliable, gender-inclusive information. It’s a straightforward tool designed to track your period, fertility, and any form of birth control you might be using, with zero judgment.
Spot On lets you log your cycle details, but its real power comes from its birth control tracking. It sends reminders for the pill, patch, ring, or shot, and offers direct access to expert advice if you mess up. The language is refreshingly inclusive, making it a safe space for everyone who menstruates, regardless of gender identity. It’s a no-nonsense, education-first approach.
Why It’s a Contender
This app’s biggest advantage is its source: Planned Parenthood. You’re getting evidence-based information from a trusted nonprofit, not a company trying to sell you something. It’s completely free, without ads or premium paywalls. While it lacks the deep analytics of some other trackers, it excels at its core mission of providing accessible health education and reliable tracking. It’s the best free period tracker for anyone who values expert-backed content and inclusivity above all else.
Access: 100% free on iOS and Android.
Best For: Users who want a gender-inclusive app with expert-backed birth control and cycle education.
Heads-Up: Lacks the advanced predictive analytics found in data-heavy commercial apps.

9 Euki – Privacy‑First Period Tracker
If the thought of your cycle data being sold to the highest bidder makes your blood run cold, meet Euki. This free, open-source app is the nonprofit-backed, privacy-first period tracker for anyone who’s truly had enough. Built by sexual health experts, Euki doesn't just track your period; it keeps all your data locked down on your phone, away from advertisers, data brokers, and anyone else who doesn’t need to know.
Euki operates on a "local-first" model, meaning your information never leaves your device. It’s PIN-protected and even has a "fake screen" feature in case someone demands to see your phone. Beyond tracking, it offers a wealth of actually useful, non-judgmental sexual health info, from contraception to abortion resources. It’s the digital equivalent of a locked diary combined with a straightforward health textbook.
Why It’s a Contender
Euki’s main draw is its radical commitment to privacy. As a nonprofit, it has no financial incentive to monetize your data. This is a crucial point, given that many other period apps are probably spying on you. It’s the best free period tracker for the activist, the skeptic, or anyone who believes their health data is their own damn business. While it might lack some of the flashy features of commercial apps, its integrity is unmatched.
Access: Free on iOS and Android.
Best For: Privacy-focused users and those who want reliable, inclusive sexual health information.
Heads-Up: The interface is more functional than fancy, and it lacks community features or advanced symptom analysis.
10 drip – Open‑Source Period & Fertility Awareness App
For the true privacy purists and tech-savvy among us, drip is the period tracker equivalent of going off-grid. It's a free, open-source, and community-driven app that doesn't just promise privacy—it’s built on it. There are no ads, no trackers, and no cloud servers secretly hoarding your data. Everything lives on your device, exactly where it belongs.
This app is particularly powerful for those practicing the sympto-thermal method of fertility awareness, with detailed charts for tracking symptoms and temperature. It features a password lock, data import/export functions, and a refreshingly gender-inclusive design that feels miles away from the pink-washed mainstream. It’s a tool, not a lifestyle brand.
Why It’s a Contender
drip’s entire existence is a middle finger to data-hungry corporations. Its open-source nature means anyone can inspect its code to verify its privacy claims—a level of transparency you won't find anywhere else. It’s the best free period tracker for someone who wants total control and zero corporate bullshit. The downside is that its community is smaller. But if you value transparency and local-only data storage above all else, drip is your answer.
Access: Free and available on Android.
Best For: Privacy advocates, open-source enthusiasts, and those using the sympto-thermal method.
Heads-Up: The user base is smaller, so community support isn't as vast as with mainstream apps.
11 Ovia: Fertility, Cycle, Health
Ovia is the overachiever of the period tracking world, aiming to be your companion from your first period to your last and every life stage in between. It’s not just a period tracker; it’s a full-blown health app that wants to help you conceive, navigate pregnancy, and tackle perimenopause. If you want one app that attempts to do it all, this is a strong contender.
It offers daily fertility scores and extensive symptom logging, integrating with Apple Health and Fitbit to pull in even more data. The app is packed with a massive library of expert articles and community forums, so you can get lost in health content for hours. It’s less of a quiet journal and more of a bustling health resource.
Why It’s a Contender
Ovia stands out for its sheer breadth of features offered for free. It’s one of the few apps that genuinely tries to support you across different life stages without immediately hitting you with a paywall. The ability to export your data is also a huge plus for doctor visits. However, its real power is unlocked if your employer or health plan partners with them for premium coaching, which feels a bit like high school cliques. Still, for a comprehensive, free period tracker that can grow with you, Ovia is a solid choice.
Access: Free app on iOS and Android.
Best For: Those planning for conception or wanting a tracker that covers multiple life stages beyond just periods.
Heads-Up: Some of its best features are tied to employer-sponsored health plans, which feels a bit exclusionary.
12 Period Calendar – Period Tracker by Simple Design
For Android users who want a classic, no-frills digital calendar, this app is a veteran in the game. With over 100 million downloads, it’s a straightforward, reliable workhorse that does exactly what its name suggests. It tracks your period on a calendar, predicts fertile windows, and reminds you to take your pill without a ton of distracting extras.
You can log a decent range of data, including flow, cervical mucus, weight, and symptoms, giving its algorithm enough info to work with. It even has a partner mode, if you feel like sharing the intel. It’s a popular choice for a reason: it’s lightweight, it’s maintained, and it provides solid free functionality. It’s the kind of app that gets the job done without trying to be your new best friend.
Why It’s a Contender
This app is a solid, free period tracker for the Android crowd who prefers function over form. Its massive user base means it gets regular updates, so you’re not downloading an abandoned project. While the free version is ad-supported, the ads aren’t overwhelmingly invasive, and you can pay a small fee to get rid of them. If you just want a simple calendar view and dependable predictions on your Android device, this is a time-tested option that won't let you down.
Access: Free on Android (with ads); optional in-app purchase to remove them.
Best For: Android users looking for a traditional, highly-rated calendar-style tracker.
Heads-Up: The user interface feels a bit dated, and the ad-supported model isn't for everyone.
