There's nothing that takes the shine of a new purchase as much as seeing the same item on sales for less than you paid for it moments after you've emptied your wallet. The Idealo app aims to make these type of 'doh' moments a thing of the past. It lets you quickly compare the prices of over 1 million products from more than 20,000 online shops to find the cheapest deals.
You can search for products either via text, EAN numbers or by using the built-in bar code scanner that uses your handset's camera to capture the barcode of products that you might spot while you're out perusing real life shops. The user interface is very slick and clean looking and the app responds quickly with search results.
Idealo's smart presentation, good range of features and large database of retailers make it a good way to quickly compare online prices for products.
