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.
Free — sections, WAV export, everything. Sign in only if you want your tempo library backed up and synced across devices.
Play, pause, scrub around, slow the video to half speed — the click follows the video, not the clock. Songs that change tempo or time signature halfway through stay locked too: the tempo map carries every change with it.
Cut a song into sections, each with its own BPM and time signature. Loop one passage, get a count-in before it starts so you come in ready, and drill it until it sits.
Every video you map lands in a song library with folders, saved as you go. Send a setup to a bandmate or a student as a link — it opens right on YouTube, even if they don't have the extension yet.
Sections, loops, the library, WAV click-track export — all free, no sign-in. The one paid part is cloud sync across computers, about ₩1,100/mo once it opens — it's still being built.
