This app will use a "Wayz" like function to help the user find a parking spot a previous user occupied.

Being sure of your current spot is also a common problem
This app will also go through a on screen checklist of possibilities in the area such as no standing, bus lanes, street cleaning days, etc. in order to validate your parking.

If they pass the checklist test they're good to go.
Members who pay monthly will have a more thorough checklist
