Read product reviews and find better alternatives by scanning barcode Is there a way to read product reviews and find alternative products/suggestions by scanning a barcode with my Galaxy Nexus? I found searchreviews, but it was not so good. If not, are there any web services to achieve this?
I use ShopSavvy Barcode Scanner to scan barcodes and check for reviews. It works with Google books and other services. You can also let it search online; it will open your browser and search the barcode.

I'm not sure about alternatives, though. But if it takes you to Amazon, Amazon can give you recommendations.
