About

FuelRing is a calorie and macro tracker that respects you: no account, no ads, no subscription, and no data collection. Everything you log stays on your phone. Download it free, log your food, and if you want the advanced features, unlock them once for a single price — forever.

What it does

  • Nearly 1,400 foods built inEvery cut of steak and chicken, seafood, vegetables, fruit, grains, dairy, restaurant favorites from the chains you know, Mexican and Asian dishes, desserts, coffee drinks, street food, sauces, and supplements — plus 128 alcohol entries, from spirits and wine to nearly 30 cocktails and the beers and seltzers people actually drink. Fiber, sugar, sodium, saturated fat, and cholesterol on every food.
  • Barcode scanner that opens straight to the cameraPoint your camera at a product and log it instantly — even liquor bottles, which carry no nutrition label; FuelRing works out the standard pour for you. Unknown codes can be looked up in Open Food Facts (you can turn this off), and any food you create can be linked to a barcode.
  • Color-coded ringsCalories, carbs, protein, and fat as rings that fill as you eat, with macros shown per meal, not just per day. Micronutrients appear as mini rings in a collapsible Nutrition section.
  • Import your history from MyFitnessPal or CronometerComing from another tracker? Import your export file (CSV or .zip) and your meals, weigh-ins, and workouts come with you. Existing entries are never duplicated. Free by design.
  • Exercise, water, weight, and body measurementsAn exercise log with 24 built-in activities that estimate calories from your body weight, water tracking with a goal you set, weight check-ins that adjust your calorie target, a smoothed trend line that ignores daily water-weight bounce, and waist, chest, arm, hip, and body-fat measurements.
  • A weekly view that banks caloriesThe weekly budget strip banks calories you save early in the week for the weekend, with judgment-free wording. Save any meal and log it again in one tap.
  • Dark mode and full SpanishComplete Spanish localization — the interface, every food name, coach lines, and share text — with auto-detect on first run, plus auto, light, and dark appearance.
  • Works with Apple HealthFuelRing reads steps, active energy, and weight from Apple Health, so any device that syncs there works: Apple Watch, Garmin, Oura, Whoop, Withings, and more. Automatic sync is part of FuelRing Pro; without Pro you can import an Apple Health export file from Settings. Active energy is shown as its own Move ring and is never added to your calorie budget behind your back.
  • FuelRing Pro — one payment, yours foreverYour real burn (daily calorie burn measured from your own logs and weigh-ins), daily coach insights, 30-day and 90-day trends with consistency and streak tracking, a goal forecast from your real weigh-in trend, recipes logged by the serving, unlimited saved meals, automatic Apple Health sync, net-carbs mode, and diary export to a spreadsheet.
  • Built around your privacyFuelRing has no servers. There is no account to create and nothing to sign in to, because there is nowhere for your information to go. The single optional network feature is looking up an unrecognized barcode, and the only thing sent is the barcode number itself.

Your data

  • No accounts, no analytics, no advertising SDKs, no tracking. FuelRing collects nothing.
  • Your profile, diary, custom foods, saved meals, weigh-ins, water, and exercise are stored only on your phone. There is no server.
  • One optional network request: looking up an unrecognized barcode in Open Food Facts. Only the barcode number is sent, and you can turn it off in Settings.
  • Apple Health access is read-only (workouts, sleep, steps, active energy, weight) and stays on your device. FuelRing never writes to Apple Health and never transmits Health data.
  • FuelRing Pro is a one-time purchase handled entirely by Apple. We never see your payment details.
  • Backups and CSV exports are created on your device and saved wherever you choose.
