The in-car version of Zapmap has three main features:

Locating charge points
You can see all the charge points close to your current location, identify suitable points using the filters or search another area.

Viewing live charge point status
You can see the details of each charge point including live charge point status data (where available) and the latest EV driver chats.

Accessing route plans
You can pull up routes that you have planned on the mobile app and punch out to Apple Maps or Google Maps to get turn-by-turn directions.
