PerfectFast

Readings on the fast clock. The Fast Timeline now charts what a fast did to your body: weight, blood glucose, and blood and urine ketones, each on the fast's own clock from start to now, with the estimated stages as the ruler. Hold a chart to read any value with its time into the fast, or lay a previous fast of similar length beneath it to compare hour for hour. Heart & Body from Apple Health. Turn on resting heart rate and heart rate variability in Settings to see them as daily context under the charts, with a seven-day reference for resting heart rate. Body fat percentage, lean body mass, and body mass index appear as records beside your weight, and sleep is drawn night by night across a multi-day fast. A Journal day that reads as one story. Everything you log now sits on one rail in the order it happened, with the fast's start and end as anchors and the day's totals on top. Chips narrow the rail to one kind, a dense hour of glucose readings folds into a single row, and one Log menu adds anything to the day. The day's fasts sit above the rail as cards with their duration, target, and span. Fasted days at a glance. The calendar and the week strip tint every day you fasted, and each month in the Journal overview closes with its tally: time fasted, fasts, and days fasted. Progress now opens on the current week. Also: the timer ring animates far more efficiently, so the Fast tab feels lighter.
