12 Best Free Period Tracker Apps (2026)

Every app below has a real free version — no trial that expires on you. We've also flagged the ones that keep your data on your own phone, since that's the question a lot of people actually care about now.

Hand-checked · no affiliate links
How we checked: each app was confirmed to have a genuinely free tier as of this month. "Freemium" means the core tracking is free and there's an optional paid upgrade. "On-device" means your cycle data is stored on your phone rather than on the company's servers — the strongest privacy position. Free tiers and privacy policies change, so double-check anything that matters to you before you rely on it. This is a resource roundup, not medical advice.
