CountIn is a browser tool for musicians who use backing tracks live. It solves a common problem. Practice apps often have a count-in, but it disappears when you export the file. This tool automatically finds your track's tempo and beat one, then permanently adds a synchronized count-in to the audio itself. You get a file that's ready for the stage.
It handles the essential adjustments needed to prepare a track for performance.
The whole process happens in your browser. You don't need to create an account to get started. Just upload a track, hear a full preview of the changes, and tweak it until it feels right. Your audio files are kept private, with processing happening locally for previews and server-side files deleted after export. It's a one-time purchase for lifetime access, not a subscription.
