OBD Auto Doctor

Works great, you have to buy the full version to clear codes, but it's worth it to have this tool wherever you go. If you're looking for an adapter to use it with, I ordered one on Amazon from BAFX Products, it says Android only, but it does fine with windows phone 8.

Ok for ten bucks, would like a logging mode to see trends etc over the duration of a trip.

Was really surprised to find such powerful App in Windows Phone Store. Connects and works perfect with ELM327 on Audi A4 B6

This app is not worth 10$. More like 3$. Doesn't let you change units of measurement. Barely any freedom to personalize to your liking. There are other apps with more options and cost less.

Paid for pro version but disappointed with features. Using high-end ObdLink-LX BT dongle. Can see lots more sensors with my ScanGauge. Dashboard is useless.
