Ratings and reviews

UPDATE: August 2026 This app has sadly gone downhill. 75% of the time recording tracks don't even register, the sound quality hasn't improved and the biggest issue is the EXTREME latency - it's impossible to create any projects. Searching for new app. WHY is the playback sound so harsh?! Am I doing something wrong? It sounds HORRIBLE. Just high-pitched static noise. Is it me or is it this app? I can't even use this for more than one track if it's going to sound like this!

Perfect for quick/on-the-go recording when you have an idea for a song and you don't have access to any recording equipment. Works better than the standard sound recorder that's included on most phones. Use it with earphones that have a built-in microphone and it works pretty well for multitrack recording, so you can record a track and listen to it playback while recording new tracks. Awesome little app.

Exactly What You've Been Looking For. This app lets you record 4 simple tracks. No annoying ads, no forced social bs, just you and 4 tracks to lay down rhythm, lead, vocals, and more. It's a singer's dream. Easy to drop 4 harmony tracks with any melody that pops in your head at any time. Love the autosave feature and worry free transitions between this app and others. Well done! 👍
