SpotAngels is an app that helps you avoid parking tickets. It does so by sending you reminders before/about street cleaning, tow away, alternate side parking, and other parking restrictions. The app caters to more than 20 cities in the States, including San Francisco, New York, Boston, Detroit, Dallas, San Antonio, etc. Besides helping you avoid parking tickets, the app also comes in handy when looking for parking space. The application uses your car’s Bluetooth or other motion sensors for functioning. If a specific neighbourhood is missing information, parking signs pictures from the area could be sent from SpotAngels and data would be updated within 24 hours.
