How it works
Three taps from camera to better choice
Open the camera, scan or snap, get the score. Everything else builds on that.
Open the camera
Tap Scan. The camera opens with a soft viewfinder, ready for whatever you point it at.
Scan or snap
Hold over a barcode, or tap Capture for produce, a receipt, or a menu. Zarte handles all four.
Get the score + swaps
A 0-100 score tuned to your goals, the nutrition breakdown, and gentler swaps if you want them.
What's happening behind the scan
Curious about the magic? It's mostly not magic.
- Barcodes look up against OpenFoodFacts, an open community-maintained product database with millions of items.
- Produce, receipts, and menus are analysed by AI vision models. Photos aren't kept after the scan.
- The 0-100 score is sugar-led but honest: sugar and glycemic load carry the most weight, with saturated fat, sodium, fibre, and protein as sanity checks so a low-sugar item cannot slide past just because it swapped one problem for another. Tap 'Why this score?' on any result to see the math.
- Personalisation runs on-device. Your scans stay private; your scores adjust to your goals.
Scan for sugar. Swap for better.
