Sotto
sotto voce
/ˌsɒtoʊ ˈvoʊtʃeɪ/
In a quiet voice, as if to avoid being overheard.
Italian — literally "under the voice"

Every app on the market looks like exactly what it is.

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.

You deserve an app nobody would ever question.

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.

Three steps. Zero learning curve.

01
Connect
Turn on your device. Open Sotto. It finds your Lovense, We-Vibe, Satisfyer, or Lelo automatically via Bluetooth.
02
Choose a skin
Pick from 7 extraordinarily boring disguises — calculator, white noise mixer, podcast player, and more.
03
Control invisibly
Check off a to-do. Tap a calculator key. Adjust a white noise slider. Every familiar gesture secretly controls your device. Triple-tap anywhere for instant stop.

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 devices you already own

Your secret is safe at every layer.

touch_app
Triple-Tap Stop
Tap anywhere three times. Device stops instantly. No menus, no confirmation dialogs. Under 200ms.
widgets
No Suspicious Icon
Sotto's home screen icon can be set to match whatever skin you're using. Calculator icon for calculator skin. Podcast icon for the podcast skin. Nothing to explain.
notifications_off
Zero Notifications
Sotto never sends push notifications. Nothing on your lock screen, nothing in your notification center. Ever.
flip_to_front
App Switcher Safe
When you switch apps, the app switcher shows your current skin — a calculator, a podcast player, or whatever you've chosen. Not a control interface.
signal_cellular_alt
Signal Fade-Out
Walk too far from your phone? Intensity fades smoothly as signal weakens — no jarring surprise stop. Get closer and it comes right back.
credit_card
Discreet Billing
Your app store subscription appears under a neutral developer name. No one auditing a credit card statement will know.

We know nothing about you.

No account required
Open the app and use it. That's it.
No cloud
Everything stays on your phone. Zero server communication.
No analytics
No tracking, no telemetry, no usage data. We don't know how or when you use Sotto.
No data collection
We don't store device names, usage patterns, or anything else. Period.
No location access
Sotto never requests your location. No GPS, no geofencing, no location history.
No hidden files
Nothing written to your photo library, file system, or iCloud. Uninstall and it's gone completely.

Questions you'd rather not ask out loud.

The most discreet app
is the one nobody notices.

Works with the device you already own. Looks like an app you already use.
