Body Rhythm Log

A private event tracker: log with one tap, review on a simple calendar, with optional reminders and a lock. No account, no streaks, no pressure.

Overview

Body Rhythm Log is a simple and private way to track your personal patterns. No streaks. No pressure. Just log events with a single tap, view your history in a clean calendar, and stay aware of your own rhythm over time. There is no account to create and no complicated setup.

Your log is among the most personal records you can keep, so Body Rhythm Log is built local-first: your entries are stored on your device, not on a server. A privacy lock overlay with local authentication helps keep the log for your eyes only, and optional reminder notifications use discreet wording that does not reveal what you are tracking.

The app stays intentionally simple, with minimal design and no distractions. It is a personal log, not a medical tool, and it offers no diagnosis, predictions, or health advice.
