Vibrator apps look like vibrator apps.
Hearts, purple gradients, pattern names like "Pulse" and "Surge." One glance from the wrong person at the wrong moment — and they know.
Manufacturers invested years making the hardware quiet, small, and invisible. Then they shipped it with an app that announces itself to anyone within eyeline of your screen.
Sotto closes the gap. The hardware is discreet. Now the software is too.
Each skin has its own hidden controls — a volume slider, a scroll position, a calculator key — that adjust intensity and play patterns. It looks like you're just using an app. Only you will know what's really happening.
Multiple devices, one screen. Connect two or more devices at the same time. Same pattern, same intensity, perfectly in sync, perfectly in secret.
Works with the device you already own. Looks like an app you already use.
