How we build

From an everyday problem to a live app

  1. Start with a real problem

    Every app begins with something people do every day and find harder than it should be.

  2. Design it simply

    We keep screens clear and tools easy to find, so a new user can get going without a manual.

  3. Build and release

    We build in small steps, test as we go and release on the web and, where it fits, on Android.

  4. Keep improving

    We run the apps ourselves, listen to feedback and keep fixing and adding things after launch.
