SNAQ app on iPhone showing today's meal log and nutrition summary without a CGM

SNAQ is a carb counting app for diabetes that uses photo recognition to estimate carbs, protein, fat, and fibre from a meal photo in seconds. Unlike manual food diaries or database-search apps, SNAQ identifies ingredients automatically, making it one of the few carb counters validated in a peer-reviewed accuracy study and a randomised controlled trial.

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.

Photo carbs

One photo. Instant carb and nutrition breakdown.

SNAQ's AI-powered food recognition handles ingredient identification, portion estimation, and macro lookup automatically. You just point the camera.

Photo recognition Voice logging Manual override available

Every result is editable. Adjust ingredients, swap portions, or override the carb total. The AI gets you started, you stay in control.

Common questions.

How accurate is photo-based carb counting?

In a 2024 head-to-head accuracy study (Journal of Diabetes Science and Technology), SNAQ reduced carb estimation errors by 38% compared to self-estimates by 53 adults with T1D, and outperformed a competing app. The underlying volumetric technology was validated in controlled conditions across 48 meals and 128 food items, achieving a mean absolute carb error of 5.5g (JMIR mHealth, 2020). Real-world results will vary depending on the meal and conditions.

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. SNAQ's 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.
