About RunCadence

RunCadence is a single-page running log built around two ideas.

Local-only by default

Every byte you generate stays on this device. No accounts, no sync, no analytics on what you log. The price you pay is that your data does not appear by magic on a second device — you export and import a JSON file when you need to move it.

Lightweight on purpose

There is no map, no GPS, no heart-rate import. You log a date, distance, duration, and effort. From those four fields RunCadence produces weekly streaks, pace trends, personal records, and a yearly goal trajectory. The math runs on your device.
