Singing app questions
Something else on your mind? Ask us after you reserve.
Which songs can I use?
Any song you have as an MP3. You bring the song and its lyrics, and Mochi works out the melody and lines up the words.
Can a singing app help me sing in tune?
It helps when it shows you what your voice is doing while you sing. sing mochi draws your pitch as a line over the song's notes and tells you to go a bit higher or lower, so you learn to hear the difference and fix it yourself. Short, regular practice on songs you like works best.
Is sing mochi a karaoke app?
Yes, and a singing coach too. It makes a music-only version of your MP3 to sing over, shows the lyrics in time with the music, and scores how closely you follow the melody.
Do I need to read music?
No. You follow a line on the screen, and Mochi tells you "a bit higher" or "a bit lower" in plain words.
How does it know which note I'm singing?
It listens through your microphone and measures the pitch of your voice many times a second. For your song, it separates the singer's voice from the band to map the melody you're aiming for.
Will it work with my headphones?
Yes, including AirPods and other Bluetooth headphones. You pick your mic, and sing mochi adjusts for the small delay Bluetooth adds.
What does "lifetime Version 1" mean?
You pay $20 once and keep everything in Version 1 for good. Big future versions may be a separate upgrade, and you can choose whether you want them.
When does it launch?
We'll email you the moment Version 1 is ready. That's also when the remaining $15 is due.
