Works well, dashboard provides all I need. Would like to see engine temp value larger, very hard to read.

Cannot connect to a Citroen DS4...I tested more than 10 OBD applications, no connection issues...I tried to connect to my ELM327 for 3 days, no succes. A few years ago I used your application on a Mazda 3, 2006, and it was perfect...I enjoyed a lot using it...but this time is a nightmare...

Nice little app. Two years ago I have bought the full (Pro) version because I liked the app very much, and I was happy with it, until the author renamed the full version to Smart Control Premium, which requires a new buy. The "Pro" version is not upgraded anymore. This policy is unfair, and I regret buying the full version.
