## Core Features

### AI Snap
Take a photo of your meal and get instant nutritional analysis powered by advanced AI. Estimates within 10-20% accuracy. There is no barcode scanning and no database searching by design.

### Four ways to log
Photograph the plate, type "avocado toast with two eggs and coffee", ask Siri ("Hey Siri, log my lunch"), or message the Telegram or WhatsApp bot. Everything syncs to the iOS app.

### 42 nutrients tracked
Beyond calories and macros: iron, vitamin D, omega-3, B vitamins, zinc, magnesium and dozens more, from the same logging you already do. Tap any meal for the full breakdown, and the AI highlights the nutrients that need attention.

### Track
Log meals, view nutritional breakdown, and monitor daily intake with an intuitive interface. Log from iOS, Telegram, or WhatsApp - always in sync.

### Exercise
Log "30 minute run" and the AI estimates the burn. Activity calories go into the daily budget.

### Goals
Set personalized calorie and macronutrient targets using scientifically-validated formulas (Mifflin-St Jeor equation). Presets for balanced, high-protein, keto, GLP-1, heart health and plant-based.

### Progress
Visualize your nutrition journey with insights and trends over time. Weekly AI briefing, eating timeline, macro and calorie trends, weight charts, and progress photos at each weigh-in.

### Water and daily routines
One-tap water tracking with a daily breakdown, plus routines for supplements, meals or habits.

### Widgets and Live Activities
Six home screen widgets (Quick Input, Daily Summary, Water, Health Score, Routines, Macros) and calorie progress on the lock screen in real time.

### GLP-1 Support
Shot tracking with estimated medication levels, injection site rotation, and side-effect logging for GLP-1 users (Wegovy, Ozempic, Mounjaro, Zepbound).

### Logging on a bad GLP-1 day
Appetite and nausea vary a lot on GLP-1 medication, and most tracking tools assume every day is a good one. Because kcalm logs from Telegram and WhatsApp, you can record a meal by sending a single message or photo to the bot without opening the app at all. That matters on days when you eat very little, eat at odd hours, or do not feel like opening a tracking app. The same day still counts toward your protein and calorie targets, so a hard day leaves a real record instead of a gap.

## Scientific Foundation

kcalm calculations are based on peer-reviewed research:
- BMR: Mifflin-St Jeor equation (1990)
- Activity factors: Standard Harris-Benedict multipliers
- Macronutrients: Atwater system (4/4/9 cal per gram)

## Privacy Highlights

- Photos processed for analysis only, not stored permanently
- Data encrypted in transit and at rest
- Row Level Security ensures data isolation
- Users can delete all data at any time

## Pricing

- Free: 15 AI food analyses + full tracking features, no credit card required
- Telegram and WhatsApp bots: 3-day free trial
- Premium: unlimited AI analyses, USD 14.99 per month or USD 69.99 per year (about USD 5.83 per month)
- No ads at any tier, and no tiered feature gating beyond the analysis limit
