Comments on Sing2Notes – AI Vocal Notes for Android
★★★★★Justin Lloyd Long· Oct 22, 2025
I've used the free version of this app twice and so far it's been brilliant. It doesn't always identify the intended notes but to suggest that this isn't due to my awful voice would be absurd. I may well upgrade to the full version in the future depending on whether it's subscription or a one-off payment. Great work.

★★★★☆Rebecca Chanice Acohon· Oct 15, 2024
Gets the notes right most of the time. I just wish there's an option to show the note names (e.g C, D, E, etc.) on the scale
★★★★★Shelley Mitchell· Aug 26, 2025
It really does work !! I wrote a song, and it wrote the sheet music plus recorded my singing
★☆☆☆☆chloe wickert· Nov 13, 2023
Doesn't transcribe the notes correctly. I'll give it simple voice notes from a hum, and it can't even transcribe that correctly either. Extremely disappointing.
★☆☆☆☆John· Feb 24, 2024
I uploaded a song that was written and sang by one of my students who wanted it transcribed into musical notation. It was in the key of A-flat major. The app transcribed it in G# minor. Not only were the notes wrong, and some notes missing, but it can't even tell what key it is in!? Worthless! I'm glad I didn't pay for this app!
★☆☆☆☆Hamed Amin· Sep 16, 2025
Utterly awful and useless, even after I paid for premium version, the app doesn't work at all. Any attempt to upload and add a link for transcription ended up by errors, so I strongly disagree to suggest it. By the way the UX UI design of the app was again awful. How do you dare to sell subscriptions when even only one file failed to be uploaded let alone to be transcribed?????
