Calcifer is a lightweight, distraction-free nutrition tracker. AI estimates calories and macros instantly, while everything you log stays on your device—with zero accounts and no subscriptions.
Everything you need to hit your health goals without the bloat of traditional calorie tracking apps.
Type your meal or workout in plain English (like "grilled chicken breast with quinoa and avocado"). Calcifer automatically calculates carbs, fat, protein, and calories.
Visual radial charts and progress bars display your remaining daily calorie targets and carbohydrate, fat, and protein thresholds at a single glance.
Your data is yours alone. No accounts, no emails, no remote tracking. Everything is saved locally on your device with lightning-fast offline access. AI estimation sends only the meal or workout being estimated to our API, which doesn't store it.
Quickly re-add frequent meals and activities from your recent library. Adjust portion sizes in grams or duration in minutes seamlessly.
Monitor 7-day, 30-day, 90-day, and all-time macro balance trends with interactive multi-metric charts and daily average bars.
Fine-tune your personal Basal Metabolic Rate (BMR), TDEE, weight goals, and customize your exact percentage split for carbs, fat, and protein.
