Local Cycle vs drip: Two Local-First Period Trackers Compared

Q: Is drip a good private period tracker?

Yes. drip is open source, stores data locally, has no accounts and no tracking, and focuses on fertility awareness with symptothermal-method support. It is one of the most credible privacy-first trackers available.

Q: How does Local Cycle differ from drip?

Both are local-first with no accounts. drip is free, open source, and centered on fertility awareness. Local Cycle is a paid app focused on life-stage breadth: irregular-cycle prediction windows with condition context, perimenopause mode, pregnancy loss logging, pregnancy milestones, and a postpartum year.

Q: Why choose a paid app over a free open-source one?

Pay for it only if it covers needs drip does not -- perimenopause, pregnancy loss, postpartum, condition-aware prediction windows, encrypted backups, and doctor reports. If your need is fertility awareness charting, drip is excellent and free.

This is a comparison between allies. drip and Local Cycle share the same core belief -- menstrual data belongs on your device -- and differ mainly in focus: drip is a free, open-source fertility awareness tool; Local Cycle is a paid tracker built for life-stage breadth, from irregular cycles through perimenopause, pregnancy loss, and postpartum.

Where drip is genuinely great

drip, built by the Bloody Health collective in Berlin, is open source, gratis, and methodologically serious about fertility awareness. Anyone can audit its code, which is the strongest possible transparency claim -- stronger than any policy document, including ours. If you chart BBT and cervical mucus for the symptothermal method and want a free, auditable tool, use drip with our blessing.

What Local Cycle adds

Local Cycle's scope is wider than charting. It is built for the parts of reproductive health most trackers skip:

Irregular-cycle prediction windows with condition context for PCOS, perimenopause, endometriosis, thyroid disorders, POI, and elevated prolactin.
Perimenopause mode -- hot flashes, sleep, mood, sexual health, and an HRT/intervention timeline.
Pregnancy loss logging that preserves your history and pauses predictions while you recover.
Postpartum mode -- 52 weeks of recovery and baby-milestone tracking, with vaginal-birth and C-section tracks.
Encrypted backups and doctor reports -- portable files you control, plus PDF reports for appointments.

The one-time $9.99 purchase funds that development without ads, analytics, or a subscription treadmill.

How to choose

Choose drip if your primary need is fertility awareness charting in a free, open-source tool. Choose Local Cycle if you need life-stage coverage -- perimenopause, pregnancy loss, postpartum -- or condition-aware prediction windows. Either way, you have chosen the right architecture: your data stays with you.
