Gestures
- Swipe up / down anywhere — set the BPM (0.1 steps, 20–300).
- Drag the right-edge scale — jump straight to an absolute BPM.
- Hold a second finger — fine mode: the swipe slows ~10× for decimal nudges.
- Single tap — flip between half-time (×½) and double-time (×2).
- Two-finger tap — cycle the beat style (Orbit, Ripple, Sweep, Pulse, Bare).
- Shake — switch to a random theme.
VoiceOver
With VoiceOver on, focus the tempo and swipe up/down to change it; double-tap the mode row to flip half/double; use the rotor's Actions to change the beat style or theme.
FAQ
The haptic ticks aren't firing.
Haptics only work on a physical iPhone, not in the Simulator, and require that System Haptics are enabled in iOS Settings → Sounds & Haptics.
Where did my settings go?
Doppio stores everything on-device. Deleting the app clears your saved BPM, mode, beat style, and theme.
Does Doppio need internet?
No. It works fully offline and makes no network requests.
