Limited capabilities for modern Subaru’s

Limited capabilities for modern Subaru’s. Disappointing

Maybe the best app I have ever seen / had

This is by far the best app I have ever had. I ended up buying some monitors and sharing the app with my best friend. They still can’t believe how well it works. Me too. Thank you

This app is generally useless for anything but pulling a trouble code without getting suckered into spending more money for that specific make.
By AnotherRippedOffUser

Easy to install and configure the basics but…

I’ve bought this app for both Android and iOS. Android app is identical with iOS app on my iPhone - they have the same exact PIDs for logging. However, this app is not graphing nor logging HP nor Torque on my iPad (8th Gen). Whereas in my iPhone 11 Pro Max and Galaxy S7, the app graphs and logs HP and Torque. Both iOS devices have been updated to the latest iOS 15.1 Knocking two stars until a solution is given.

Works when it wants to

Too many issues with this app. Hardly ever pulls actual codes too. Not worth it at all. All my other applications have no issues with connecting to the device so it’s this application that is broken.

Paying 10 bucks for a free app I got with my obdreader then having to pay 10 to get it to actually work and then it has issues communicating on modules and still can’t clear errors absolute waste of money you are warned
