Fasting timers count hours. Unpause counts fat. Start a fast and watch your estimated fat burn tick up live, gram by gram, as your body shifts from the sugar in your last meal to stored fat. SEE THE FAT YOUR FAST BURNS • Live grams of fat burned and your burn rate right now (g/h) • A fuel bar that shows how much of your energy comes from fat • Six fasting phases, from digesting to deep fat-burn, so you always know where you are EVERY HOUR BURNS MORE FAT • A burn curve for every fast: asleep, waking up, the fat switch at around 12 hours, and the climb to your goal • See why the last hours of a fast are worth finishing A FLAME FOR EVERY DAY • Your last 7 days at a glance: one pixel flame per day, lit by how much of your goal you reached • Reach your goal and it burns in full • Tap a day to see that fast KNOW WHEN YOU'LL HIT YOUR GOAL • A goal-date forecast from your body, recalibrated with every weigh-in • Weight trend, BMI and fat burned per week WORKOUTS MAKE YOUR FAST BURN FASTER • Log a walk, run, ride, strength, yoga or HIIT session and see the extra fat it adds • Workouts can bring your fat switch sooner • Import workouts from Apple Health NO FOOD LOGGING REQUIRED Your daily plan number is enough.

Unpause Plus unlocks live fat burned on every fast, the burn curve, widgets, Live Activity, the Apple Watch app, workouts and Apple Health import, weigh-ins and your goal date.
