Lala — learn to sing by singing

Field notes

The homepage demonstrates the core interaction rather than merely describing it: target-note bars sit beneath a live trace of the singer's pitch, with feedback measured in cents. The app describes 20 exercises across five units, each retuned to the user's vocal range, plus phrase-by-phrase scoring for whole songs. A party mode supports two to eight singers passing around one phone, while recorded takes are stated to remain on the device rather than being uploaded.
