Tap a note and the choir has its starting pitch. Every note from C3 to B5 with an adjustable A4, so the group starts in the right key. Fully on-device: no cloud, no account. Pick the octave, tap the note, and it plays a clean tone. It needs no microphone, so it works in a church, a rehearsal room or the car on the way to a gig. • 12 notes per octave, octaves 3 to 5 • A4 reference you can move away from 440 Hz • Works offline, with no mic permission For choir leaders, a cappella and barbershop groups, brass bands and singing teachers. Pitch Pipe+, part of Pro and SUS4 All-Access, adds a drone that holds the note, chord drones (major, minor, sus2 and sus4), intervals, glide and five tones from sine to plucked. Made in the UK by working musicians. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
