PulseSync

PulseSync is a fully offline rhythm tapping game built around clear visual timing. Play through 40 handcrafted practice levels split into four chapters. Each run uses visible beat markers, three lanes, and a judgement line so the timing stays readable even with the sound off. Levels gradually introduce alternating taps, simultaneous dual taps, and hold notes without overwhelming the player. The game includes a first-run calibration flow that estimates your local timing offset using a short flash sequence. You can adjust the offset later from settings, reset it at any time, and keep the result stored only on the device. After every run, the app shows judgement counts, lane balance, streaks, and the weakest 15-second segment so you can immediately retry a focused practice window. Progress, best accuracy, recent runs, and accessibility preferences are saved locally and restored on the next launch. Helpful options include left-handed lane order, reduced motion, larger judgement lines, assist patterns, sound feedback, and haptic feedback. The entire experience stays offline and does not require an account, cloud sync, ads, payments, or downloaded music.
