Two-week experiments • Each goal is now a two-week experiment. Pick a few habits, try them for 14 days, and Preffect tracks the days you showed up. • Your goal page shows what day you’re on and the numbers we’re watching. Tap a number to see more. • On day 14, one check-in covers all your goals. Then plan your next two weeks with one tap. Goals and habits • A goal’s page shows only that goal’s habits, with Done right in the row. • No habits yet? Tap “Add one” to pick from suggestions. • Move a habit to a different goal from its page. • Habit history shows six weeks at a time, with “Show earlier weeks” for more. • At five habits, swap one out right from Home. Quick Wins • Tap Something else to tell us why, and your next Quick Win will fit better. Getting started • See what Preffect will watch for your goal before connecting Apple Health. • If Apple Health fails to connect, you can now tap “Try again.”
