Managing calories is hard. Tracking shouldn’t be. TowerCal helps you log food, calories, and exercise quickly, then turns your day into a touchable, color-coded calorie tower. Type or speak an entry, review the estimate, and see where today stands. SEE YOUR DAY AT A GLANCE Every entry becomes part of the Day screen: - Food and drinks stack as visible calorie tiles - Exercise appears as burn context - Your daily goal guide stays in view - Selected nutrient colors show what contributes to protein, fat, sugar, sodium/salt, fiber, calcium, iron, and other supported nutrient totals LOG THE WAY THE MOMENT ALLOWS - Type a quick food, calorie, or exercise note - Speak a short entry - Add a favorite image as a visual cue - Reuse favorite entries - Add custom foods - Enter calories directly - Edit or delete entries when estimates need correction KEEP THE RIGHT NUMBERS CLOSE - Consumed and remaining calories - Net consumed and net remaining calories - Expected and projected calories - Selected nutrient totals - Reports across recent ranges - Weight history and trends TowerCal is designed for calorie-aware adults who want a simple daily answer: where does today stand? TowerCal is not a diet program, social fitness platform, fasting app, macro coach, or medical nutrition tool. AI-assisted logging can draft entries faster, but estimates can be wrong and should be reviewed. Favorites, edits, custom foods, and direct calorie entry keep the tracker useful when AI is not the best fit. Use TowerCal for calm daily calorie awareness, flexible food and exercise tracking, and a visual Day screen that makes meals, snacks, drinks, and movement easier to understand. Safety note: TowerCal is for adults 18+ who can track calories safely. TowerCal is not medical advice. Consult a qualified professional before using calorie tracking for medical, clinical, eating-disorder, pregnancy, or pediatric needs.
