Rep Counter

Stick your phone to the weight stack with the magnetic case, then start the warm-up set. Needs motion sensor access — must be served over https:// (or localhost) to work.

Recording sequence
  1. Hold still for 3-5 seconds with the weight stack resting.
  2. Pull the bar into the exercise starting position.
  3. Hold that position for about 1 second.
  4. Perform the repetitions.
  5. Hold the starting position briefly after the final rep.
  6. Return the weight stack to rest.

Signal (projected acceleration)

Displacement estimate & triggers

noise/setup exercise region
Displacement is acceleration integrated twice, so small sensor bias becomes drift. The displayed trace is drift-corrected within the exercise region; its zero level is arbitrary. Dashed lines: upper 70% arms the counter, lower 30% counts the rep. Dotted lines show average peak/trough.
Rep debug will appear after analysis.
