The projects

devpKishan/FocusGuardOpen-source Android productivity app with app blocking, timers, and screen-time tracking (candidate implementation of core loop for Android).Open on GitHub

What you give up either way

  • Reliable, hard OS-level blocking on iPhone/mac without MDM or platform vendor cooperation
  • Polish, cross-platform consistency (iOS, macOS, Android) and App Store/Play Store scale
  • Opal’s branded UX, rewards/gamification persistence at scale and community features
  • Enterprise/team features and account management/SLAs

An open-source project doing the core job proves a replacement is possible. It does not prove it matches Opal, and it does not prove anyone has run it for a month. How we decide.
