PulseSync

An offline rhythm trainer built for short, focused sessions. Train against visible beat lanes, clear timing windows, and original note patterns designed for quiet or silent play. Start with a three-beat count-in, hit single taps, then move into alternating lanes, paired hits, and hold notes as the set opens up. Use the first calibration flow to capture a local timing offset, or fine-tune the judgment offset later in preferences. The app keeps calibration, scores, best accuracy, and recent runs on the device only. Review each run with precise, good, early, late, and miss counts, plus combo history, lane bias, and the weakest 15-second segment. Replay that segment to sharpen the part that needs the most work. Preferences let you switch sound feedback, haptics, reduced motion, left-handed layout, track spacing, widened judgment feedback, and auxiliary lane patterns. A guide and privacy statement are included, and no network login, cloud sync, ads, payments, or external song downloads are used.
