Cant beat the price
I bought this app to monitor my engine vitals but use it specifically for boost/vacuum and coolant temps. It works great so far but i do run into occasional issues. Im using an elm 327 odb2 wifi adapter which connects to the app great but because im connected through wifi it wont let me play streaming apps such as pandora or netflix.
I think its best to use this app with an old phone or an ipad so you dont use your primary phone and lose its functions/capabilities but its worth its price compared to spending 100 bucks on a scanegauge
