Principles

Same rules for every project.

Different platforms, different problems. The way they're made stays the same.

Small and focused

Each app does one job and does it well, without menus you never use.

Your data stays with you

Cards, parking spots and files stay on your device. Something only leaves it when you choose to share.

Made for each platform

Real widgets, lock screen and Dynamic Island on iPhone; native apps on macOS and Windows.

Built from feedback

Bug reports and ideas from people using the apps decide what gets fixed and built next.
