An independent app studio in San Francisco
Apps for the people,skills and obsessionsworth your time.
We make a small number of apps, each for something that matters. Some help you connect with the people across the table. Some help you really learn a thing. And some go deeper into a single hobby than anyone probably should.
Connection
Hear the person across the table.
Restaurants, cafés and bars, rated on one question: can you follow the conversation? Made for people who are hard of hearing, hearing aid and cochlear implant users, and anyone who processes sound differently.
- Patio, booth, bar and main room, each rated on its own
- The best time of day to go
- A ten-second noise check. Nothing is recorded.

Going deep
Cold brew for the gear you actually own.
Tell it your grinder and your brewer. You get a recipe for exactly what you own, with the right setting for your grinder. Start a batch and the timer follows you to your Lock Screen. Free, with no account.
- More than 80 grinders, each drawn with its own grind scale
- 20 brewers, from a mason jar to a gallon dispenser
- A steep timer on the Lock Screen and in the Dynamic Island
- A bean journal that improves your next batch

Learning
Learn the game before you sit down.
- Coming soon to the App Store
- Play money only
- 18+
Blackjack and Texas hold’em, played the way a casino plays them. A retired dealer coaches you through every hand and tells you why each play is the right one.
- A blackjack pit and a poker room, with regulars who come back night after night
- Honest about the odds. The house always has an edge, and the app says so.
- Play money only. Nothing to buy, nothing to win.
Ridotto is coming soon to the App Store. It’s for adults 18 and over, uses play money only, and never offers real-money gambling or prizes. If gambling stops being fun, call 1-800-GAMBLER.
About the studio
Small apps, made carefully.
Some of our apps help you connect with people. Some help you learn something properly. Some exist because we got a little obsessed.
Every one starts with something people actually care about. We build the part that matters, keep adjusting until it feels right, and leave out anything that gets in the way. Our apps start on the App Store, and we’ll bring them to more platforms as they grow.
