Parking Reminder shows every public charger in Austria on the map, with how many plugs are free right now, the plug types and the power. Where the operator states it, you also see the price per kWh and the idle fee.
The data comes from E-Control Ladestellenverzeichnis, where operators must publish their chargers and live status under EU rules (AFIR). The app refreshes it every few minutes.
Tell the app which plugs your car takes and how fast it charges, and it suggests only chargers that fit, ranked by the power your car really gets. A charging timer reminds you to unplug before an idle fee starts.
