For: Singers sketching song ideas without a studio
Worth noticing: Two-bar vocal input can be exported as a sketch, MIDI, or WAV file.

Field notes

Sing Lupa exposes a compact music workstation rather than a simple recording button: users can choose tempo, bar count, swing, key snapping, octave, quantisation, and whether a track uses the synth, their voice, or both. It includes an example to sing over, local sketch storage, device installation, and export paths for a small sketch file, MIDI, or WAV. The page notes that headphones help prevent the microphone from capturing the beat.
