The Essential Shopping Companion

CartWise turns your phone into a smart shopping list — one that keeps your spending honest while you’re still in the store, not after you’ve paid.

Scan a barcode and CartWise looks it up against an open product database, which covers most well-known packaged goods. Where it doesn’t recognise something — a local product, a store-brand item — you enter the name once yourself. Either way, CartWise remembers it from then on: the next time you scan that same barcode, the price you paid last time pre-fills automatically, along with the store and date. Over time, your own scans quietly build a personal price book, with no store integration required.

How it works

• Scan — barcode lookup fills in the name automatically for recognised items
• Confirm or name it — unrecognised items just need a name typed in once
• Price memory — CartWise remembers what you paid, where, and when, and pre-fills it next time
• Live budget meter — set a weekly budget and watch it track in real time as items go in, green while you’re safe, red the moment you go over
• Finish trip — logs the shop by store and date, building a spending history you can look back on
