The problem
People rarely fail because they lack another calorie database. They fail because logging is tedious, estimates feel fake, and daily energy balance is hard to reason about in real time.
Vision
Nutrition apps often ask for too much and explain too little. CalorieSnap starts with a narrower promise: help people see whether the day is headed toward deficit, balance, or excess before bed.
People rarely fail because they lack another calorie database. They fail because logging is tedious, estimates feel fake, and daily energy balance is hard to reason about in real time.
Food labels are incomplete, restaurants are inconsistent, and a single guessed number can create false confidence. Activity and sleep also matter, but they are usually separated from the meal decision.
If food scanning, user correction, and Apple Health context live in one evening balance, people can make better decisions without obsessive tracking.
Show ranges, not fake certainty. Make every estimate editable. Use calm colors, clear hierarchy, and direct language. Encourage adequate eating and safer decisions, never starvation.
A deficit can be useful, but an extreme deficit is not a win. A surplus is information, not a moral failure. The app should help a user understand the tradeoff and choose the next reasonable action.
