User reviews

Really enjoying so far

It’s simple and easy to use, and I’m excited to see more songs added soon!

Response from developer

Really appreciate hearing this! Thank you!

Options

Only a few options of songs, and when singing, it suddenly says that I’m either: not singing at all or hitting a whistle now! It’s so bad and unrealistic!

Response from developer

Thanks for flagging this. We investigated and found that some Bluetooth headphones can cause unreliable pitch readings. We’ve since added an in-app warning and recommend using the iPhone’s built-in microphone or wired headphones for the most accurate results. We’re expanding the built-in song selection. You can also use Freestyle, write your own songs, or use custom song codes.
