STONO

STONO is a smooth stone that lives inside your phone.

When your mind is restless and your hands can't sit still, there is an age-old comfort in rubbing a smooth stone. STONO has brought that sensation to the screen. There is nothing to read or set up. It is simply a dark, silent surface that responds to your touch.

Rub, and the stone answers. Fine dots move along your fingertips, and soft sounds rise and fade. The longer you use it, the finer the texture becomes. Like a pebble that has been in your pocket for years, it becomes smooth with your touch.

■ It feels like this

· Rub anywhere. The surface moves along your fingertips.

· Sound plays in real-time every time you rub. It is neither a recording nor loop playback.

· Swipe sideways to change the shape and sound.

· The texture becomes finer with use.

■ Made simple

· No accounts, no logins, no ads.

· It collects nothing. Everything is inside your device. · Works completely without the internet.

· Just a single dark screen. Nothing to learn.

STONO doesn't fix you or observe you. It is simply a small, quiet thing for those moments when you need something to hold onto.
