Both Coles and Woolworths have very popular apps in both the IOS App Store and Android Maket, they are essentially apps that appeal to a wide audience and are very helpful when you are in your preferred local supermarket. Unfortunately for Windows Phone 7 users, neither Coles nor Woolworths have any plans to release a Windows Phone app in the near future or at all at this stage.
If you want to see these apps head on to a Windows Phone handset, reach out to Woolies and Coles to let them know you want it!
