Focus Explicit Support

Focus Explicit is a paid, ad-free timer for focus blocks and breaks.

FAQ

Does the timer need the internet? No. Timing and history stay on your iPhone.
Does the app show ads? No. There are no ads and no tracking.
Is there a subscription? No. Focus Explicit is a one-time App Store purchase.
Why does the app ask for notifications? Only to tell you when a focus or break session ends. You can turn this off in Settings.
I changed the duration and nothing happened. Pause or finish the current session first. New lengths apply to the next block.
