About the studio

Monkey Patching is an independent software studio run by Paweł Kowalak, a professional software engineer building native iOS apps in his own time. Every app is small on purpose: one clear problem, solved well, with the kind of care you only get from someone who actually uses the thing.

A few principles run through everything we ship:

  • Privacy by default. Your data stays on your device. No accounts to create, no analytics, no third-party trackers.
  • Offline-first. The apps work without a connection and don't depend on a server staying up.
  • Native & honest. Built with SwiftUI for iOS, no dark patterns, no ads — and we say plainly what each app does and doesn't do.
