About
An independent studio building focused apps and games.
Castlegate Studios makes software for two groups of people: tabletop players and tradespeople.
What we do
We build focused apps and games. Each one does a clear job, and does it well.
How we work
- Focused. We'd rather do one thing well than many things halfway.
- Respectful of your data. This website uses no tracking and no cookies.
- Independent. We're a small, self-directed studio.
Our apps
Hearth: GM & Player Companion is a tabletop RPG companion app for game masters and players, made by Castlegate Studios. It runs character sheets, GM tools and maps for fifth-edition games. r1r2, a test-results app for electricians, is in development. More games are on the way.
