See exactly where to save.

Savings opportunities screen

Snap a receipt and Guuster shows you which items had a cheaper alternative — and where. Your Smart Shopper score tracks how often you're getting the best deal, so you always know where you stand.

  • Item-by-item savings breakdown after every receipt scan
  • Smart Shopper score that tracks your shopping efficiency over time
  • Personalised suggestions based on what you actually buy, not generic deals

One app, no borders.

Cross-border price comparison screen

Guuster works across Switzerland, Hungary, Romania, and the Euro zone. Living near a border? Compare prices across countries to find out if it's worth the trip to that nearby supermarket abroad.

  • Compare prices across borders — see if shopping in a neighbouring country actually saves you money
  • Live exchange rates so cross-currency comparisons are always accurate
  • Store finder with proximity search — find the cheapest shop near you
  • Works with any retailer — every receipt you scan automatically adds new stores and chains to the network

Better data, together.

Product discovery and community screen

Every receipt you scan enriches a shared price database. Scan barcodes to link products, verify prices from other users — the more the community contributes, the smarter Guuster gets for everyone.

  • Scan barcodes to enrich products with images, brands, and categories
  • Crowd-verified prices so you can trust what you see
  • Every contribution matters — new scans, verifications, and product links
How It Works

Three steps to
smarter shopping

01

Scan

Take a photo of any receipt or import from your gallery. Guuster extracts every item and price automatically — nothing to type.

02

Compare

Every item gets compared across the retailers in your country. You see where you overpaid and where to go next time.

03

Save

Monthly trends, store comparisons, and savings tips show you exactly what to change — which items and which stores.

The App

Built for the
way you shop

Track purchases, compare prices, and spot savings — all from your phone.
