LooPeR by FanStaF
A pedal-style looper for Android. Built for musicians.
LooPeR is a low-latency Android looper inspired by classic single-button stompbox loopers like the Boss RC and TC Ditto. Tap to record, tap to play, tap to overdub — long-press to undo. No setup required, no menus to fight through. Under the hood it runs a native Oboe/AAudio engine in exclusive-mode where the device supports it, with per-device latency calibration so your overdubs land where they should. Plug in a USB audio interface and play guitar straight into your phone, or use the built-in mic for vocals and percussion. When you want more than just freeform looping, switch to structured mode: set a tempo, time signature (odd meters welcome), and count-in, and every take snaps to the bar. Completely offline. No accounts, no ads, no tracking — your loops stay on your device.
