Photograph your meal. Get a carb estimate you can trust. Log what you actually ate — and watch how your glucose responds.
Carb counting is the hardest daily task for someone living with type 1 diabetes. SimpleCarb makes it fast, accurate, and automatic — without ever telling you what to inject.
Rest your thumb at the plate edge as a scale reference. One photo, full plate. The AI uses the thumb to estimate volumes — no weight scales, no ingredient scanning.
Claude vision identifies every food, estimates carbs, protein, fat and calories, and flags its confidence. Your API key never leaves the server — only a number comes back to your phone.
Photograph leftovers, or tap All / Most / Half / Barely. The app stores both the AI estimate and your actual portion, so accuracy improves over time and nothing is lost.
Most apps estimate the full plate, then guess how much you ate. SimpleCarb photographs both: the meal as it arrives, and the leftovers when you're done. That second photo turns a rough estimate into a precise record.
Live glucose from your Dexcom appears alongside every meal log. Correlate what you ate against what your glucose did — the insight that drives better decisions over time.
All data lives on your device. No account, no cloud database, no third-party sync. The AI call passes through a proxy that adds the API key server-side and returns only the estimate — your photos are never stored anywhere else.
Log fast and long-acting insulin doses, hypo treatments, and life events alongside meals. The timeline shows everything together so patterns become visible.
Designed for real life: logging with children present, at a busy table, mid-conversation. Fewer taps always wins. The meal-in-progress banner rescues anything left half-done.
SimpleCarb is a SimplySoft lab project. If you're building something at the intersection of AI and health, let's talk.
