FAST. MEASURE. PROGRESS.

Track fasting and body measurements privately.

FastMetry is an app for adults to record fasting periods, body measurements and progress. Your records stay in the app on your device. There is no account or cloud sync.

Getting started

Choose your measurement units and usual fasting plan, then start a fast or plan your week. Add measurements whenever you want. History, charts and the body view help you review what you recorded.
