About
Every other calorie tracker runs on guesswork — search a database, eyeball a portion, hope for the best. DEFICIT doesn't guess.
Point your camera at your plate and DEFICIT reads it: calories, protein, the full breakdown, in seconds. Didn't quite get it? Tell it. "Fried in butter." "Double the chicken." "No rice." Your voice makes the number true — and you can remove anything it got wrong with a tap. One blind guess isn't tracking. This is.
Then DEFICIT does what trackers won't: it connects everything. Your weight, steps, sleep and training on one timeline, read back in plain English. And a coach that answers from your actual numbers — ask "push or hold today?" and it already knows.

What's New in DEFICIT

August 8, 2026
Onboarding now explains the system properly. The bar starts full, empties as you eat, and charges back when you move — shown one step at a time instead of all at once. The scanner demo shows the real result sheet, so what you see before signing up is what you get after. Home reads cleaner: one notice rail instead of pop-ups in three different places, every notice dismissible, and the activity log sits where you expect it with last night's sleep and HRV alongside your burn. Log now shows carb and fat targets, not just protein. Notification settings are legible and consistent — the enable button was unreadable, and it isn't any more.
