I've been using this App for a while now and it's pretty simple and useful.
Since it's free and the guy has not asked for any donations or support at all, I've been trying to offer support in the way of reporting a properly desiganted M/C parking space everytime I come accross one.
The thing I like about it is he's willing to take the time to add in any reports, not just those in the big cities.
It might just help you out and I'm sure he would appreciate any support from the lesser travelled areas, so if you're willing chip in and report your finds. It's really easy to do from within the App. I have no connection to the guy at all.
