Food Tracker for Type 1 Diabetes
Log meals, estimate carbs, and see how food relates to your glucose patterns. Built for the daily reality of Type 1 diabetes.
What is a food tracker for Type 1 diabetes?
A food tracker for Type 1 diabetes helps you record meals, estimate carbohydrates, and keep food context connected to your glucose data. SNAQ makes this easier with photo-based meal logging, carb and macro estimates, and glucose insights that connect with Dexcom, FreeStyle Libre, Contour, blood glucose meters, and 20+ other devices.
Carb counting is one of the most demanding parts of living with Type 1 diabetes.
Restaurant meals are harder to judge than meals at home. Mixed dishes are harder than single ingredients. And even familiar meals can vary in ways that are difficult to account for manually. At the same time, CGM data is easier to learn from when you know what was eaten and when. SNAQ connects food logging with glucose context so the daily effort of tracking meals produces more insight, not just more data.
Estimate carbs with a photo, then see how the meal moved your glucose.
Point your camera at any meal and SNAQ's AI estimates carbs, protein, fat, fiber, and calories in seconds. Connect a CGM or blood glucose meter (Dexcom, FreeStyle Libre, Contour, and 20+ others) and view each meal alongside your glucose data. Save frequent meals to reduce daily logging effort.
Built on clinical evidence.
Fewer carb estimation errors
In a peer-reviewed study, SNAQ reduced carb estimation errors by 38% compared to self-estimation in 53 people with T1D.
JDST, 2024Mean absolute carb error
Across 48 meals and 128 food items in a peer-reviewed accuracy study, SNAQ achieved a mean absolute carb error of 5.5 g.
JMIR mHealth, 2020Time in Range
Published RCT result in T1D patients on AID systems, measured over 12 weeks of SNAQ use.
eClinicalMedicine, 2025How people with Type 1 diabetes use SNAQ
- Estimating carbs at restaurants, including mixed dishes and plates that are hard to weigh
- Logging repeated meals and snacks faster with Favorites to cut daily effort
- Reviewing meals alongside CGM data to understand postprandial glucose patterns
- Saving family meal carb estimates for consistent daily logging at home
- Sharing a detailed food history with an endocrinologist or dietitian at appointments
- Using voice or barcode logging when photographing a meal is not practical
The only consumer nutrition app with published clinical evidence in diabetes.
Validated in a randomised controlled trial with T1D patients on automated insulin delivery. Participants spent more time in their blood sugar target range.
