A Menstrudel alternative for tracking plus optional support
Menstrudel keeps the product offline, open-source and solo. BaeMax adds encrypted selected sharing for one trusted person.

Menstrudel is the stronger fit for a free open-source tracker on Android or iPhone that works offline, supports biometric lock, imports and exports data, and handles pill or LARC reminders. Android users also get a Wear OS companion. Choose BaeMax only when selected partner support, shared check-ins or care tasks justify adding a controlled sharing path.

Open source gives a different kind of evidence
Menstrudel publishes its code and describes local-only operation. That lets technical reviewers inspect implementation instead of relying only on public claims.
BaeMax accepts more coordination complexity
Partner delivery requires a service path even when content is encrypted before it leaves the phone. That trade-off enables support but is not equivalent to a fully offline tracker.
If inspectability is the point, pick Menstrudel
Open-source review is a real reason to choose Menstrudel. BaeMax is for the one-pair support experience, not code inspection.
Choose the smallest data exposure that does what you need
If no sharing is needed, a focused offline tracker may be enough. Add partner features only when they reduce real care work. Offline storage also changes the backup problem: a lost or damaged phone can take the only copy with it. Before relying on any local tracker, confirm its export format, decide where an exported file can be stored safely, and test recovery without putting the cycle record into an unnecessary cloud account.
