Our principles behind everything we ship.
Written in Swift and SwiftUI. Our apps feel like they belong on the platform because they are built for it.
We collect as little as possible (if possible nothing). Where data can stay on your device, it stays on your device.
Support emails come to us directly — not a queue. Most replies go out within one working day.
Bug reports, feature requests and questions are all welcome.
