Boost your creativity and transcribe your vocal songs into sheet music. All the features of Sing2Notes: » Transcribe solo vocal recordings to sheet music » Transcribe solo vocal MP3 files to sheet music » View the transcribed music as classical score » Playback the sheet music and listen to the result » Download sheet as PDF, MIDI, or MusicXML » Share your compositions with your friends HOW DOES IT WORK? Once your music piece is uploaded, our artificial intelligence powered transcriber processes it to generate a sheet music based on what it hears. When the processing is finished, you can view the final sheet and export it in three outputs - a Midi file, a PDF engraved sheet, and a MusicXML digital note sheet. It has never been easier to convert piano pieces to sheet music! WHAT THIS APP DOESN'T OFFER » Separation of multiple instruments: The note recognition can't separate multiple instruments from your voice. If you record multiple instruments playing simultaneously you will get bad transcription results! As the name says, Sing2Notes will only work with vocal recordings. » Live note recognition: This app is not able to show you live note recognition results. Instead, it will take some time to perform the frequency analysis and shows you the final sheet music. » 100% match percentage: This app won't detect 100% of the played notes and there will also be wrong detections. But depending on the quality of the input signal, it will give you more than useful sheet! REQUIREMENTS » Internet: active internet connection for server connectivity » Microphone SUMMARY Transcribe music recordings from your microphone to sheet music. With Sing2Notes you can create on-the-go recordings of your voice. Those are uploaded to your personal songbook and transcribed to score. Musical note recognition for piano has never been so easy!

Verdict
The clearest difference is rating: Sing2Notes at 3.6 against KODAI's 2.2. Sing2Notes also leads on ratings volume (79 vs 5) and review sentiment (31% vs 21%). KODAI's advantage is in-app purchases (none vs 8) and update cadence (every 10 days vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
