Food is the one part of diabetes that still feels manual. Whether you are cooking at home, ordering takeaway, eating out, or trying something new on holiday — Bettie takes the guesswork out of carb counting so you can enjoy your meal, and the hours after. Subscription required for full access. Pricing is shown in the app before purchase. **Snap a photo. Get the carbs.** Take a photo of your plate and Bettie breaks down the carbs, protein, fat, and calories. It works with homecooked meals, restaurant plates, street food, packaged snacks — anything. You can also scan a barcode, photograph a receipt, or just describe what you are eating. **See how meals actually hit** Connect your CGM data and Bettie maps every meal to your glucose curve. Instead of guessing which meals work for you, you can actually see it. **Build your personal playbook** Over time, Bettie builds a picture of how you eat. Search your history for similar meals, compare glucose responses side by side, and spot the patterns that keep you in range. **Refine with a conversation** Not sure about the portion? Something you have never had before? Ask Bettie. The built-in assistant can refine estimates, pull up past meals, and give you context on your glucose trends. **Four ways to log. Zero friction.** - Photo / snap your plate - Barcode / scan packaged food - Receipt / photograph a receipt or menu - Text / describe it in your own words **Glucose insights that actually help** - See which meals keep you steady and which ones surprise you - Compare similar meals side by side - Track patterns and trends over time **Built for people who count carbs every meal** Bettie is not a diet app. It is built for people who count carbs all day, every day - at home, at work, eating out, or on holiday. The goal is to make food feel less like a maths problem and more like just eating. Terms of Use: https://bettie.app/terms
