That depends on your need. If you are going to be using it a lot (ie you travel, RV, or install), then yes. If you are going to use it one time, probably not. Unless of course an installer will charge you more than $20 for something you can do yourself, and this app will help outI agree, however the only one I find on my phone is the Pro, but now online I see this one, but it too is $ 20, but it's FOR the android.
Would you go with this one ?
