Unfortunately the app is unstable and hogs an enormous amount of memory. If you can get it to run without crashing your phone, it gives alerts about memory warnings and "switching to lightweight view", and then doesn't actually show street-level parking data. At least, that's my experience. Hopefully they'll fix it in future versions coming soon.
