Question Any app I can use to measure cellular 4g lte or 5g data signal constantly on phone with results saved?

Is this even possible on a iPhone ?

There's tons of different apps but, constantly saving the results isn't usually an option due to the space this would take up on the phone. Now, if you don't mind it snooping and uploading signal stats in the background that's a different story. However, this comes up time and again regarding IOS....

Why don't you have an iOS app?
Apple doesn't allow apps to use the network info API.
