A calorie tracker you can actually stick with. Scan a barcode, see what's in the product per portion as well as per 100g, and log it against your own daily target. Staying consistent earns XP, levels and badges.

Open Food Facts, a free and open database of food products with strong UK coverage including supermarket own-brands. It's crowd-sourced, so the occasional entry is incomplete — where a value is missing Scran shows it as unknown rather than pretending it's zero.

You'll be able to enter the details off the packet yourself, and Scran remembers that product against its barcode so you only ever do it once.

Logging food earns a few XP each time, up to a daily cap. Finishing the day inside your calorie band is worth more, and a consecutive-day streak adds a growing bonus. Scanning a barcode or trying a brand for the first time pays a discovery bonus, as does building a recipe or recording a weigh-in.

No, deliberately. Hitting your target pays the same flat amount whether you land exactly on it or come in under, so there's never a reward for undereating. Weight badges are milestones you pass rather than a scoreboard, and nothing scales with how fast you lose.

A hundred of them across a thousand levels, changing every tenth level. Twenty families of five tiers each — you start at Nibbler I and work up through Taster, Grazer, Forager, Gourmand, Epicure, Connoisseur, Gastronome and the rest, finishing at Scranmaster V. Getting there is a matter of years, not weeks.

Quickly at first and slowly at the top, which is the point. The first few levels land in days, and the curve stretches from there — a thousand levels is a long-haul goal, not a weekend one. There's always another rank in sight.

Not necessarily. You get one forgiven day a month automatically, and more as you climb the ranks. One forgotten Tuesday shouldn't wipe out two months of effort.

Never. Deleting or correcting a diary entry keeps the XP it earned — fixing a mistake shouldn't cost you anything. Re-logging the same thing can't earn twice either, so there's nothing to game.

Nothing. Every diary entry stores its own snapshot of the calories and macros at the moment you logged it, so a later correction upstream never rewrites what you already ate.

In Scran's own database on the server it's running on. Your food log is tied to your account and isn't shared with anyone.
