Most calorie trackers hold you to a strict daily limit. Cal/d tracks your daily average instead, so one heavy day doesn't wreck your progress. Set a start date and daily limit, and Cal/d reads dietary energy from Apple Health to show: - Score: a 0–100 read on how today is going, from your pace, room left and daily average. - Daily Average: total calories since your start date, divided by days elapsed. - Remaining Calories: stay under your limit and you build a surplus to spend whenever you want. - Surplus Goal: surplus divided by daily limit is how many days you've saved. Set a target (say, 3 days). - Countdown to Next 250: a timer until your next 250 calories, expandable to 5 timers ahead (20 with Plus). Don't want to wait? Factor in Active Energy too. A jog raises your surplus and moves you closer to your goal. Log calories and nutrition directly in Cal/d, or keep your current tracker and open it with one tap from a built-in link list. Anything that writes to Apple Health, Cal/d can read. On Apple Watch, turn the Digital Crown through your Score, budget, pace, average, goal, and countdowns, and add complications to your watch face. PLUS FEATURES: - Unlimited What-If calorie planning - Unlimited surplus-goal days - All 20 countdown milestones - Custom Chart date ranges longer than 30 days - "Last…" Chart periods beyond the last 7 days - Score breakdown - After-exercise pace comparison - Live Activity on the Lock Screen and Dynamic Island - Calorie checkpoint notifications Cal/d is not medical advice. Consult your doctor before changing your diet.
