Good app, but – Speedometer 55 GPS Speed & HUD Review

I have used this app back in 2017 but stopped using it for a while because of a problem. I had the paid version, but then i got a new phone. And i cannot find a way to restore a purchace. If this is possible, please let me know how. also, does the map have a dark mode?
