This one is another application just for the UK, but as we have near on 9 million BlackBerry users here it should go down well. I'm pretty sure that most folk here in GB know that Nectar is the number one shopping points collecting system. The more you spend, the more points you get that can be redeemed at a bunch of retail outlets.
The Nectar app for BlackBerry 10 allows you to keep an eye on just how many points you have saved up and what that equates to in pounds. In addition, the application will inform you of special Nectar offers such as getting double points at certain places. BBM is integrated so you can share these offers with your friends if you so desire.
GPS is built into the app so you can view all the retail locations near you where you can use your card. With Sainsbury's being one of the top supermarkets here I expect most customers use a Nectar card but within the app you may be surprised just to see how many other places you can use/spend your points.
There is however one thing missing from the app that really frustrated me - and that's that there is no barcode which means you can't use the app as your actual Nectar card in-store. I've passed over my feelings to BlackBerry who will feed the information on to Nectar but as it stands the iOS and Android versions are also lacking this feature.
You can grab the Nectar app for free from the below link.
