Caltopia
Nutrition tracking that stays on your phone.
Caltopia is a private, offline-first wellness app. Snap a photo of your plate and on-device AI suggests what it is, or log with barcode, voice, or one-tap recents. See trends, hit goals, build streaks — all without an account or a cloud.
What's inside
AI Photo Scan
Snap a photo of your meal — on-device AI (Apple Vision) suggests the food. The image never leaves your phone.
Two-tap logging
Recents on Today + barcode + voice + nutrition-label OCR. Log a meal in the time it takes to think about it.
Smart targets
Calorie & macro goals from Mifflin–St Jeor + Institute of Medicine activity multipliers. Adapt as your weight changes.
Real insights
Weight, calorie, macro, and hydration trends. Weekly summaries, correlations, and a 13-week logging heatmap.
Gamified, not gimmicky
Streaks with auto-applied freezes, daily and weekly challenges, long-term quests, 52 achievements, and a leaf avatar that grows with your level.
Private by default
Everything stored on your device using Apple's SwiftData. No account, no analytics, no third-party trackers.
Apple Health sync
Optional two-way sync for weight, water, and nutrition. Off by default — you stay in control.
Important
Caltopia is a wellness self-tracking tool. It is not medical advice, not a medical device, and does not diagnose, treat, cure, or prevent any disease. Always consult a healthcare professional before changing your diet, exercise, or medication routine.
