Tap the beat once. BeatSync keeps a click track perfectly aligned with whatever you're watching on YouTube — through every play, pause, seek, and speed change.
Play, pause, scrub, half speed — the click follows the video, not the clock.
Sections with their own BPM, looped with a count-in.
Every video you map is kept, in folders, and shareable as a link.
Sections, loops, library, WAV export — free. Only cloud sync is paid, about ₩1,100/mo once it opens — it's still being built.
