Check the sugar before you eat it — and see the whole label, not just the sugar.
SugarCheck is a sugar and nutrition tracker that runs right in your phone's browser. Scan a packaged food's barcode and SugarCheck shows you the sugar and carbs before you eat — plus the full nutrition panel. Log it, and your whole day's nutrition adds up in one place.
What it does
- Scan any UPC barcode (or type the number, or search by food name) and get the numbers up front: total sugars, added sugars, and total carbs, with a clear preview of what logging the food does to your day.
- Full nutrition facts, not just sugar. Total fat, saturated fat, trans fat, cholesterol, sodium, dietary fiber, protein, calories — plus vitamin D, calcium, iron, and potassium when the source record carries them. Every value is editable, because the printed label always wins over any database.
- No barcode data? Scan the label itself. Photograph the nutrition panel on the package and SugarCheck reads the numbers off it, right on your phone. You always confirm the values before anything is logged.
- Your whole day in one panel. Every logged food adds to a full-day nutrition panel — all the facts, the whole day — alongside 14 days of history and a CSV export.
- Budgets you set yourself. SugarCheck tracks against daily sugar and carb budgets (and optional calorie/protein goals) that you choose. The app ships with clearly marked examples only — it never prescribes targets.
- Private by design. No account, no sign-up, no subscription. Your log lives only on your phone — nothing is uploaded, ever.
How it works
- Buy SugarCheck here — one payment, $19.99, no subscription.
-
Your license key arrives by email (it looks like
SCK-XXXXXX-XXXX). - Open SugarCheck on your phone (link in the same email), enter the key once, and the app unlocks permanently on that device. Add it to your home screen and it works like a regular app.
Good to know
- Works on any modern phone browser (iPhone Safari, Android Chrome). No app-store download.
- An internet connection is needed for barcode/name lookups, and the very first time you use the label-photo reader (it loads once, then runs on your phone).
- Nutrition data comes from Open Food Facts, a free crowdsourced database — some products are missing or incomplete, which is exactly why every number can be corrected from the printed label before you log it.
- One key unlocks one device. Your food log is stored on the device, so clearing your browser data clears the log (export the CSV first if you want a copy).
Please note
SugarCheck is a personal tracking tool. It is not medical advice, does not diagnose or treat anything, and does not replace your clinician, your meter, or your own care plan. Daily budgets are set by you. Always trust the printed nutrition label over database values.
