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.

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.
