Until you can eat 500 more kcal
Most trackers wipe the slate at midnight, so one heavy dinner becomes a failed day. Cal/d keeps a running average from a start date you pick, and a budget that accrues every second.
Go over on Tuesday and you have not failed anything. You have simply borrowed from Thursday.
Set a limit and Cal/d tells you the time, to the second, until you can afford your next 250, 500 or 2,000 calories. It runs on your Lock Screen and in the Dynamic Island, and the widget keeps it on your Home Screen. What-if scenarios let you move the clock before you commit to the meal.
The more remaining calories you accrue, the more days you have to spend on extravagancies and treats without guilt.
Goals help you stay on track and make informed decisions about your eating habits.
The app is free and the whole model works without paying: the average, the budget, the countdown, the Score, the chart, history and the widget. Plus lifts the limits on the planning features and keeps the countdown live outside the app. One payment of $9.99, no subscription.

Plus is bought in the app, in the Settings tab.
Cal/d has no servers, no accounts and no ads. Your calories live in Apple Health on your device, and your settings sync through your own private iCloud. Nobody, including me, can see any of it. The privacy policy is short, and that is the whole of it.
Cal/d is my answer to effective weight loss and maintenance. Most people aren't professional athletes. I built this app for the crowd that wants the flexibility to binge on occasions.
