On-device gps Canada app - anyone tried?

Noticed these apps in the app store for various countries. Anyone here try it and have a screenshots or a review?

Thanks.

I havnt but I've seen very negative reviews about the On-Device maps. I'd search around the forums more before paying money for it.

Stay away. Don't believe the reviews on appworld, just shills for the developer.

Do a search here on the developer (Skylab Mobile?) and you'll see
