Is there an app that shows this if Apple does away with the ability to change to the dBm? Might be something that could help people that use this feature like you do.

I don't see any way that would be possible. You have to remember, the field test info is not a feature for users. It's for carrier use. Most of it is useless for users. A lot of cell tower info. So, I don't see this available for developers to use in an app.
