AirPiano App vs Pendulo

Place your phone flat, hover your hands above the screen, and pinch any finger to play a note. AirPiano uses your camera to turn 8 finger pinches into 8 live piano notes — no touching the screen, no setup, no instruments. The first time it works, you'll want to show everyone around you.

Most metronomes ask you to listen. Pendulo lets you watch. Pick a visual pattern, set your tempo, and keep time with your eyes on iPhone, iPad, or Mac. Because the beat is visual first, Pendulo works where sound doesn't: practicing quietly late at night, staying locked in on a loud stage, or playing as a hard-of-hearing musician. Every pattern is built to be read at a glance. - Eight visual patterns, including a swinging pendulum, pulsing rings, and flashing panels - Tap tempo: tap along, and Pendulo finds your BPM instantly - 10 to 300 BPM, with 2 to 12 beats per cycle and a clear downbeat accent - A mute button right on the main screen, plus volume control to dial in your sound - Save a preset for every song or exercise - An auto-stop timer to end a session automatically - Color themes for any lighting or mood Free includes three visual patterns (Pendulum, Pulse, and Flash), three color themes, six core sounds, and tap tempo. A one-time purchase of "Pendulo Premium" unlocks the remaining five patterns (Arc, Star, Sweep, Circular, and Linear), an additional six color themes, sixteen more sounds, and the ability to save unlimited presets. No subscription. No ads. No data collected. Photosensitivity warning: Pendulo contains visual patterns that may include flashing or strobing effects.
