SNAQ app on iPhone showing photo-based carb counts for a meal

Carbohydrate counting is the practice of estimating grams of carbohydrate in meals to support glucose management or general nutritional awareness. Modern carb counting tools use photo recognition, AI, and validated food databases to reduce the manual entry burden and improve accuracy compared with self-estimation alone.

The problem

Manual carb logging is the reason most people stop tracking.

Type the food. Pick the portion. Confirm the brand. Repeat for every meal, every day, for years. Almost everyone gives up. SNAQ keeps the data flowing because the input is just a photo.

Common questions.

How accurate is photo-based carb counting?

In a peer-reviewed study (JMIR mHealth, 2020) the underlying volumetric technology had a mean absolute carb error of 5.5 g across 48 meals and 128 food items. In a 2024 head-to-head accuracy study (Journal of Diabetes Science and Technology), SNAQ reduced carb estimation errors by 38% versus self-estimates by 53 adults with T1D.

Can I correct the carb count if it looks off?

Yes. Every meal is editable. You can adjust ingredients, swap portion sizes, or override the carb total manually. Voice logging is also available when a photo isn't practical (cooking, driving, restaurant meals).

Do I need a CGM to count carbs with SNAQ?

No. Photo carb counting works camera-only, no sensor required. If you do use a CGM, SNAQ overlays each meal directly on your glucose curve so you can see how the carbs landed.

Do I need a prescription to use SNAQ?

No. SNAQ is consumer-available, no prescription required. Always consult your healthcare provider for clinical decisions.
