Independent software studio

acknowledgment.dev

We design, build and publish our own apps.

Acknowledgment Dev designs, builds and publishes its own applications for iOS, Android and the web — from the first sketch through to the store listing and the servers that keep them running. No client work: the roadmap answers to the people using the apps.

Ochra

A watercolour teacher in your pocket. It sets the lesson, looks at your paper between steps and tells you what to fix while the paint is still wet.

In development, 2026 · ochra.app
Tsubu

An online pixel art and sprite editor — draw on the grid, animate frame by frame, and export sheets that drop straight into Unity, Godot, Phaser and Pixi.
