The app is very clearly laid out and very easy to use. The interface is clear and you can see a list of offers in your area at a glance -- if your area is covered. The app is still in beta so it only covers 22 major U.S. cities right now. The roll out will continue so keep an eye out for your city being added soon.
If you have a Google account of any kind you can use the same log in and Google Offers benefits from integration with other Google services. For example you can pay using Google Checkout, look up businesses using Google Places to see reviews, and then navigate there using Google Maps.
It is easy to scan through the featured offers and there are a limited number at the moment. You can also scan barcodes to see whether there is a Google Offer on that item right now. It’s unlikely there will be, but if the service grows then this could be a good feature. You can purchase or save offers and then review them along with your used and expired offers.
The Google Offers app works perfectly well and the fact you can redeem offers direct from your smartphone without having to print anything is great.
