belongs to you.
No ads. Ever.
We will never put ads in any Asteria app. Your screen is for what you came to do.
Upfront by default.
Most of our apps have an upfront price. We keep in-app purchases to a minimum; when we offer them, they are upgrades, clearly explained before you buy.
Built with care, in Swift.
Our new apps put iOS and macOS first. We pair native foundations with our own typography, thoughtful interfaces and motion that knows when to stay still.

Tools for making.
Our existing creative and web projects remain part of the family, under their own licenses.
AsteriaSprite
Layers, frames and onion skin. Shading and dither brushes, outlines, rotation that keeps pixels clean. Sheets for Godot, GIFs for everyone else.
Describe a sprite and the assistant draws it with the same tools you use, one step you can undo at a time.
AsteriaBox
Chiptune or a whole band: guitars, bass, organ, strings, choir and a real drum kit. Power-chord riffs, a mix that balances itself, and MP3s ready to share.
Built on BeepBox. Every song on this page was written with it.
