Rung

Form the habits that form you.

A cross-platform habit tracker for iPhone, iPad, and Mac. HealthKit-verified completions remove the lying-to-yourself loophole, on-device AI greets you with a daily nudge, and a Spring Boot backend keeps everything in sync across devices.

  • HealthKit verifies completions — no fudging streaks
  • On-device AI greetings via Apple FoundationModels
  • Native SwiftUI + SwiftData on iOS, iPadOS, macOS
  • Spring Boot backend for cross-device sync
