See the beat.
A precision metronome with visual patterns you can practice to.
Why Pendulo?
Built for musicians who need more than a click.
Visual First
Every beat is shown clearly on screen with patterns like Pendulum, Pulse, and Flash. Practice with the sound off, in noisy rooms, or in shared spaces.

Sample-accurate click rendered directly on the real-time audio thread. Tempo adjustable from 10 to 300 BPM.
Free to start
