Canadian Tire Money app

[pipe7]

So it was reported that this was coming for ALL platforms including WP. The apps were released today and no WP app. However there is a BB app. I get that Canadian companies want to support other Canadian companies, but still seems ridiculous they would make a BB app over a WP app. It is interesting to note that all versions look identical from the screenshots provided. Is WP that difficult to port over to? I'm assuming that Android apps can be easily ported to official BB?
