AI calorie tracker

Snap your meal. Know what it's worth.

Point your camera at a plate. Trace counts the calories and macros in seconds, then tells you straight: Superfood or Skip. Streaks, quests and levels make the habit stick.

1The verdict

Every bite gets a sticker.

Numbers are only half the story. Each scan ends with one of five ratings and a short verdict from the AI, so you learn what is worth eating, not just what it costs.

  • Superfood

    Eat more of this

    Packed with protein and fiber. A great pick.
  • Good

    Solid choice

    Balanced plate. Go easy on the dressing.
  • OK

    Fine now and then

    Not bad. Add some greens next time.
  • Avoid

    Think twice

    Heavy on sugar, light on everything else.
  • Skip

    Not worth it

    Lots of calories, very little nutrition.

3The toolkit

More than a
calorie counter.

Fasting, water, workouts and weight in one place, synced with the health app you already use.

Five numbers.
One photo.

Snap a meal and the AI returns calories, protein, carbs, fat and fiber in seconds. No barcode hunting, no weighing.

Calories Protein Carbs Fat Fiber

Multi-item plates. Rice, salmon and avocado in one shot? Each item is detected on its own.

Fasting timer

Pick a window and let the ring do the counting.

Hydration

Log water in a tap. It counts toward your quests.

27

Workout presets

Calorie burn estimated with MET values, not guesswork.

Weight trend

The line that matters, without the daily noise.

Plays well with others

Two-way sync with your phone's health hub.

Apple Health Health Connect

Private by default.

Your food log lives on your phone. Photos pass through a relay for analysis and are not kept. What you eat is your business.

  • Log stored on device
  • Photos not retained
  • No API keys in the app
4Under the hood

How it's built.

Offline-first React Native. The phone owns the data, a thin edge worker talks to the vision model, and everything comes back as typed, structured data.

The app

Expo and expo-router. The food log is stored in on-device SQLite through Drizzle ORM, so it works with no signal.

offline-first

The relay

A Cloudflare Worker receives the photo and proxies it to the model. The API key lives here, never in the app.

The eyes

Claude Vision reads the plate, splits out each item and returns nutrition, a rating and a verdict.

1

Offline-first

SQLite on the device is the source of truth. The network is only needed for the scan itself.

2

No keys in the binary

The Worker holds the model credentials. A decompiled app has nothing to leak.

3

Typed end to end

TypeScript from the schema to the screen. Results land as structured data, not text to parse.
