Type 1 Diabetes

Carb counting for T1D, finally without the guesswork.

Photo-based carb counts trusted by 250,000+ users. CGM integration that overlays meals directly on your glucose curve. RCT-validated improvements in Time in Range.

Type 1 diabetes (T1D) is an autoimmune condition in which the pancreas produces little or no insulin, requiring lifelong external insulin therapy via injections, pens, or pumps. Modern T1D management combines continuous glucose monitoring (CGM) with multiple daily injections (MDI) or automated insulin delivery (AID) systems. Accurate carbohydrate counting is essential for insulin dosing, and it remains the leading source of dosing error.

The problem

Counting carbs by eye still drives the dose. That's a problem.

Most T1D nutrition decisions rest on a quick visual carb estimate before each meal. Even experienced users miss by 40–70%. Wrong estimate, wrong bolus, spike or hypo. SNAQ replaces eyeballing with photo-based carb counts so the dose can be right the first time.

Photo → Carbs → Bolus

From photo to a confident carb count in under 10 seconds.

SNAQ identifies ingredients from a single photo, returns total carbs and macros, and integrates with Dexcom / FreeStyle Libre so you see how the meal moved your curve afterwards.

Common questions.

Will SNAQ help me dose insulin more accurately?

SNAQ provides carb counts and macro breakdowns from a meal photo. It does not calculate insulin doses; that's a clinical decision for you and your care team. More accurate carb counts are associated with more accurate dosing.

Does SNAQ work with my pump?

SNAQ pairs with Omnipod 5, mylife CamAPS FX, Loop / AndroidAPS, and any pump that surfaces data via Apple Health or Google Health Connect. CGM integration covers Dexcom G6/G7 and FreeStyle Libre 2/3 directly.

How accurate is the meal recognition?

In a peer-reviewed accuracy study (Journal of Diabetes Science and Technology, 2024), SNAQ reduced carbohydrate estimation errors by 38% compared to self-estimates by 53 adults with T1D. The underlying volumetric technology was validated across 48 meals (JMIR mHealth, 2020) with a mean absolute carb error of 5.5 g.

Do I need a prescription to use SNAQ?

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