Macro & calorie tracking that updates in real time
Setting a calorie target is easy. Actually knowing where you stand at 3pm, before you decide what to eat next, is what most tracking apps get wrong. Theron's macro bar updates after every logged meal, so your remaining calories and macros are always current, not something you calculate at the end of the day.

A macro target only changes behavior if you can see it while you still have meals left to plan. End-of-day totals tell you what you already did wrong. A live macro bar tells you, before your next meal, whether you have room for it — which is the moment tracking actually influences a decision.
