Apps you end up irrationally loyal to
Haplo is one person writing Swift full-time. Nine apps on the App Store, built for people who value their time, their focus and their own data.
What this studio won't trade
100% Swift
0% Electron
native SwiftUI
Native, not wrapped
Every app is written in Swift for the platform it runs on — including the Watch app, the widgets and the Live Activities. Lean, fast, and easy on the battery.

There is no support tier and no queue. Write in and you reach the person who wrote the code — fixes tend to ship the same week.
