Bite It & Write It

Track what you eat, understand your nutrition, and hit your goals without giving up your data to do it.

Bite It & Write It is a calorie and macro tracker built around one principle: your health data belongs to you. No account required. No cloud sync. No ads. Everything you log stays on your device, in a local database only you can access.

Unlimited AI Logging (Apple Intelligence or Bring Your Own Key)
Skip the manual searching and let AI do the heavy lifting! Bite It & Write It leverages Apple Intelligence to provide unlimited food analysis directly on your phone. Describe your meal in detail, specify portion sizes, or use images to get accurate nutritional breakdowns instantly. Because this AI runs entirely locally on your device, your dietary habits never get sent to the cloud. Prefer to use a different model? You can easily plug in your own API keys to use Gemini, ChatGPT, Claude, or Grok.

Log Your Food, Your Way
Scan an item with our fully functional barcode scanner to pull up nutrition info instantly, or search millions of items from a live food database. Once you log an item, it is saved permanently to your local database, making it incredibly easy to find later with a simple text search. Adjust serving sizes, review full nutrition details, and log to any meal in seconds. All 17 nutrients scale automatically with your serving size.

Build Your Own Dishes
Create a personal recipe library with the Dishes feature. Combine ingredients, set serving multipliers, and log an entire dish to a meal in one tap. Perfect for meals you make regularly.

See Your Progress at a Glance
The home screen shows concentric rings for up to 4 nutrients of your choice: calories always on the outside, with 3 additional metrics you configure. A macro summary bar gives you a quick numeric view of where you stand for the day.

Track Water Too
Log your water intake with quick-add buttons sized for your preferred unit like cups, fl oz, or liters. Undo your last entry if you make a mistake, and watch your progress update in real time.

Reports That Actually Help
View 7-day or 30-day reports with a calorie trend bar chart, macro trend line chart, period averages, water intake summary, and consistency stats including your current logging streak. Averages are calculated over days you actually logged, so they stay accurate.

Fully Customizable
Choose which nutrients appear as rings on the home screen and drag to set their order. Set per-nutrient daily goals for all 17 tracked nutrients. Configure your default meals, rename them, and decide how many are preloaded each day. Switch between light, dark, and system themes, adjust font scale, or enable high contrast.

Multiple Profiles
Create separate profiles for different people or goals, each with their own independent nutrient targets. Switch the active profile at any time, rename profiles, or delete ones you no longer need.

Your Data, Exported
Export everything as JSON for backup or import it back later. Export your daily macro summaries as a CSV for use in spreadsheets. You own your data and can take it with you.
