Really great so far. Syncing too!

I came from Pomodoro Time Pro, which has a fairly unreliable syncing system. Focus utilizes iCloud instead, which proves to be very robust.

Ive used the task sync too. Although it works well, I use OmniFocus as my task manager. Wish it were possible to sync flagged OmniFocus actions to Focus but that wont happen.
