JMetronome

High Accuracy Metronome. I struggled with metronome drift over a few minutes with other applications, so I made this one with metronome drift Rock-solid timing. Most simple metronomes drift audibly over a long practice session because they schedule beats as a fixed repeating interval, and small rounding errors compound beat after beat. This app instead recalculates every beat's timing against a fixed reference point using full-precision math, correcting any rounding drift on every single tick rather than letting it accumulate. The result: timing stays locked in over long sessions instead of gradually creeping off-tempo — the same drift-correction principle used in professional audio schedulers, adapted to run entirely on your wrist.
