AYWAFree period trackers with no subscription, compared
AYWA makes a period tracker, and it’s one of the options here. We say so wherever it comes up, and every fact about another app links to that company’s own page.
Short answer
Three iPhone options have no paid tier at all: Apple Health’s Cycle Tracking (built into iPhone), Euki (a nonprofit app) and drip (open source).
Three more keep period tracking free but sell an optional upgrade: Flo, Clue and AYWA, which is ours. You can use any of them without paying, but you’ll see offers, and some features are paid.
Pick by what you need. For just dates, Apple Health is already on your phone. For maximum privacy with no accounts or servers, choose Euki or drip. For temperature-based fertility signs, choose drip. For more logging, estimates explained, or support beyond your cycle, choose a freemium app.
Trackers with no paid tier
Apple Health: Cycle Tracking
Already on every iPhone. Open the Health app, then Browse, then Cycle Tracking, then Get Started. You can log your period, symptoms, spotting and basal body temperature, and turn on notifications for your next period and fertile window. It also works on Apple Watch. Apple says Health data is encrypted on your device and, with two-factor authentication on, encrypted end-to-end in iCloud.
Good for: people who want something simple and private without installing anything. Less good for: people who want a wider range of things to log or explanations of their estimates.
Euki
A period and pregnancy tracker from a nonprofit, in English and Spanish. Euki says it has no user accounts and no servers: your data exists only on your phone, and deleting the app deletes it. You can lock it with a PIN, but a forgotten PIN can’t be recovered. Euki calls itself “free forever”. Its iPhone app was last updated in September 2025.
Good for: anyone whose top priority is that nobody else holds their data. Trade-off: no backup. Lose the phone and the records go with it.
drip
An open-source tracker that keeps everything on your device and publishes exactly how it calculates. Besides periods, drip supports the symptothermal method: combining basal body temperature with cervical mucus or cervix observations to identify fertile days. Its period estimate shows a most-likely start day plus alternative days, based on how regular your cycles are.
Good for: people who chart temperature and want to see the maths. Less good for: anyone who wants a quick, guided app; drip expects you to learn the method.

What “free” can hide
- Trials that renew. A free trial usually turns into a paid plan automatically. Cancel in iPhone Settings → your name → Subscriptions at least a day before it ends.
- Paywalls on things you assumed were basic. Check whether reports, trends or history are free before you invest months of logging.
- No backup. Apps with no accounts can’t restore your data if you lose your phone. That’s the price of maximum privacy; decide if it’s right for you.
- Getting your data out. Some apps let you export in one tap; others make you email support. See how exporting works in Flo and others.
- Not contraception. None of these apps is a form of birth control. Calendar estimates are estimates.
