Pulse Mobile

Recovery, strain and sleep from your Fitbit, scored on your Android phone.

No server, no account, no cloud: Pulse reads your Fitbit data from Health Connect and keeps every byte on the phone.

• Sleep, Recovery and Strain every morning, with a Strain Target for the day
• Pulse Age, Stress and Energy Bank through the day
• Health Monitor, Journal, Trends, Reports and My Dashboard

Every score is explained on the metrics pages.

On first open, allow every Health Connect permission, including past data: Pulse imports the last 180 days and only ever reads.

Expo SDK 57 with a development build (Health Connect is a native module, so not Expo Go). CONTRIBUTING.md and AGENTS.md have the rest; releases are in docs/releases.md.
