A workout isn't a day. It's a square on the grid.
■ Consistency heatmap
See your last 30, 90, or 180 days at a glance on the home screen. Days you trained glow; rest days stay quiet. Switch the range from the top left, and tap any day for that session count and volume.
■ Measured against you, not anyone else
Cell brightness is relative to your own record — a beginner's session can shine just as bright as a three-year lifter's.
■ Days trained · best streak · weekly average
Three numbers under the grid tell you where your rhythm stands. See a gap, and just start the chain again.
■ Plate loader (barbell & Smith machine)
When the coach says 62.5kg, we show you exactly what to hang on each side.
All free. Consistency beats talent.
