About

Cube

Sugar isn't a willpower problem. It's a habit with a schedule โ€” the 3pm dip, the thing after dinner, the drink you stopped tasting years ago. Cube shows you that schedule, then helps you break it. YOUR SUGAR, IN CUBES YOU CAN COUNT One cube is 4 g of sugar. Cube turns what you eat into a number you can picture, including the sugar hiding in sauces, bread, yoghurt and cereal. Most people are shocked by day one. A DAILY BUDGET THAT SHRINKS Choose cold turkey or eased. In eased mode you set where the budget opens โ€” five cubes a day, or twenty, your call โ€” and it shrinks 15% a week until you land inside the daily limit the WHO and the American Heart Association actually publish. PANIC MODE, FOR THE MOMENT IT HITS A craving peaks and passes in about three minutes. Hit the emergency button, breathe through the timer, and get a swap for the exact thing you're craving โ€” gummies, chocolate, soda, whatever your weak spot turns out to be. SCAN A BARCODE OR THE LABEL ITSELF Point the camera at a barcode and Cube reads the sugar. Or photograph the nutrition panel and it reads the figure straight off the packet, on your device. Or pick from 428 everyday foods, portions and brands included. PORTIONS YOU CAN SET Drinks in millilitres, chocolate in squares. Log 500 ml instead of a 330 ml can, or three squares instead of a whole bar โ€” the cubes follow. EVERYTHING YOU LOG, KEPT A history grouped by day with the time of every entry, and a search box for the moment you can't remember whether you already counted that coffee. STREAKS, MILESTONES AND A CUBE THAT'S ROOTING FOR YOU Days clean, cravings beaten, cubes avoided. Sixteen mascot poses to unlock and six milestones, each with a check-in that asks how you actually feel โ€” energy, sleep, skin, cravings. BUILT TO STAY PRIVATE No account. No sign-in. Everything you enter stays on your phone, and we hold no copy of it. โ€” Cube is a habit app, not a medical device. Nothing in it is a diagnosis, a treatment or medical advice. If you have a condition affecting your diet โ€” including diabetes or an eating disorder โ€” talk to a doctor before changing how you eat. SUBSCRIPTION Cube requires a subscription. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in iOS Settings โ†’ Subscriptions.
