Units
Display only — every logged weight is stored the same way, so switching never changes your history.
Background
The molten backdrop is a real-time WebGL shader — plain drops it for a static background, which is easier on battery and older devices.
1-rep maxes
Enter your 1RM — training max (used by percentage-based programs, conventionally 90% of 1RM) is computed automatically. Update a 1RM once and every workout recalculates.
About
Forge — personal workout tracker. Your data is stored privately in your own database, and sets logged with no signal are kept on this device until they sync.
