Sarah and Matt, and an octopus friend or two

Hi there! 👋

We’re Sarah and Matt, two humans who love building stuff and don’t take ourselves too seriously. We make great apps, mostly for macOS.

We aren’t interested in becoming the next Facebook, securing VC funding, or growing so big we need a sales team to set up a demo.

We build things that solve real problems. That are a joy to use. Apps that don't snoop on you, or manipulate you, or try to exploit you.

We hope you love them!
