1500cals is a calorie and exercise tracking tool I built after losing 50kg in 2022 through simply watching what I ate and starting to exercise. The main "trick" I uncovered is planning meals ahead. It sounds boring, but it's such a tiny effort for such life-changing rewards that it should be a no-brainer. Existing tools focus on tracking after eating - great for data, but it never helped me lock in a routine. I wanted to bring planning and tracking together in one easy app. This is 1500cals! HOW IT WORKS Plan your week with meals you already make and love. Add meals and snacks for each day. Connect Apple Health and your steps and workouts sync automatically - calories burned are deducted from your day like magic. 1. Sign in 2. Plan your week with meals, recipes or photos 3. Track snacks as you eat - or just snap a photo 4. Connect Apple Health 5. Eat, Exercise, Enjoy! SNAP & TRACK Point your camera at your plate and AI does the typing. 1500cals identifies the food in your photo and estimates the calories in seconds - snap, check, save. No searching databases, no weighing, no guesswork. It works when you're planning ahead too: photograph a meal once and it's ready to drop into any day of your week. FEATURES - Snap & track - AI food scanning turns a photo into calories instantly - Activity points - earn points for exercise and track your progress over time - Add your own meals, snacks and recipes - Create meal plans day by day, or copy a previous week - View detailed monthly stats for workouts, steps, and calories - 6-month visualisations that reveal patterns in your exercise and eating habits

Verdict
The clearest difference is update cadence: 1500cals at every 8 months against TheaAI's every 28 months. On price, in-app purchases and iOS requirement there is nothing between them.
