An independent studio crafting small, private apps for iPhone, iPad, Mac, and Android: games, collectors' catalogs, and everyday tools. No ads. No tracking. Built to work offline.
An App Store unlock follows you across supported iPhone, iPad, and Mac versions. A Google Play unlock follows you across supported Android devices and compatible Chromebooks. Sign in with the same store account; Apple and Google purchases are separate.
Core features work without a connection whenever practical. Some apps use the internet for fresh data or updates.
