Muninn keeps today's habits on your Home Screen and Lock Screen, and checks them off by itself when Health or Photos shows they happened. Go for a run and it's already marked done. Each habit is a row of tally marks, one per day. Glance at a widget to see what's left today, tap to mark a habit done, and watch the streak grow. LET YOUR PHONE DO THE LOGGING Muninn reads Apple Health and your photo library to check habits off for you: • Steps, exercise minutes, active energy, stand hours, water, time in daylight and mindful minutes, with a daily goal you set • Sleep and bedtime, walking, running and cycling distance, toothbrushing and handwashing • Logging your weight • Workouts: any workout, or a run, walk, ride, swim, yoga or strength session, with an optional minimum length • A new photo or video, for a photo-a-day habit Access is read only. Muninn never changes your Health data or photo library, and never uploads them. Your habits stay on your iPhone. START FROM A GOAL Tell Muninn what you want to keep up, like moving more, a calmer mind or a photo a day, and pick from habits that show how they'll be checked off. Or name your own habit and check it off by hand. HABITS YOU WANT TO QUIT • Add something to stop, like No sugar or No alcohol • Every day counts by itself. One tap marks a slip, and one more takes it back • See your days without and your longest run, with an evening check-in HABITS THAT FIT YOUR WEEK • Every day, chosen weekdays, or a few times a week • Show a habit on widgets only in the morning, afternoon or evening • A reminder at the time you pick, only if the habit isn't done yet, with a Mark as done action • Streaks that count rest days as rest, not failure • Skip today or pause a habit, and your streak waits for you • A page for each habit with its streak, completion rates and every day of the past year • Start a habit from an earlier date, and mark a past day you forgot • Tap a habit's marks to check off today, or touch and hold for more • Shortcuts, and export and import as a file WIDGETS • Home Screen widgets in small, medium and large • Lock Screen widgets in every size • Choose which habits each widget shows • A Days without widget for a habit you're quitting • Tap a habit in a Home Screen widget to check it off without opening the app • Hide habits from your Home Screen widgets once they're done FREE AND PRO Muninn is free for up to 3 habits, with the small Home Screen widget, notifications, checking off by hand, and one habit that checks itself off from Health or Photos.
