Apps that do one thing, and do it well.

Unary Systems is an independent studio building focused apps for Android and Windows. Each one solves a single problem, works without an account and respects your privacy.

What we make.

Small in scope, careful in detail.

Pentable

Android ยท Windows

Turn a Samsung Galaxy phone or tablet with an S Pen into a pressure-sensitive drawing tablet for your PC. Draw on a pure black screen while you look at your monitor, just like a dedicated tablet.

  • 4,096 pressure levels, tilt and hover
  • Works with Krita, Photoshop, Clip Studio Paint and more through Windows Ink
  • Over Wi-Fi, or USB for around 3 ms of latency

How we build.

A few rules every Unary Systems app follows.

One job, done properly

Each app focuses on a single task and goes deep on it, instead of growing into something you have to learn.

Private by default

No accounts, no ads and no analytics. Your data stays on your devices unless you choose otherwise.

Fast and native

Built with each platform's own tools, so apps start quickly, feel at home and make the most of the hardware.
