Presence — Mindful Focus
Presence app helps you regain the time lost to your phone. It has a focus sanctuary where you can pick a duration and intention, lock the screen, fade the world with ambient sound to be present, and the exit has a deliberate hold. There's also an app guard to block apps for a session or indefinitely, with recurring shields available (Pro). It's built on Apple's Screen Time API, keeping your data on your device. All focus sessions, intentions, and habits are in an offline database on your phone, and you can browse your history month by month in the Focus Landscapes calendar.
