The last time I wrote about the free apps for field testing, many people came back and suggested additional apps that are much more commonly used. In fact we got the following comment when 3G4G re-posted this
Network Signal Guru: This is surprisingly very popular and is quite useful. The only issue is that you need to have a rooted phone with Qualcomm chipset. I know many testers have their favourite phones and quite a few testers buy the latest phones, root them and start testing using NSG (Network Signal Guru).
So what can NSG do?
It can provide lots of useful information on the physical layer, cell configurations, neighbor cell lists, MIMO, etc.
You can even RAT lock to LTE / WCDMA / GSM and band lock to use a specific band. It can be very useful during surveys when you want to check if you can see particular frequency anywhere in an area. You can also see Codecs, RACH information, Data information, etc.
Finally, one of the best things I find is the signalling information. Some of the details are only available for purchased option, its nevertheless very useful. Just in case you are wondering how much does it cost, its roughly £50 per month license in UK.
Cell Mapper: I find this much more helpful as it can be used without rooting. CellMapper is a crowd-sourced cellular tower and coverage mapping service. Its simple and only used for basic testing but nevertheless very useful. To give you an idea, the other day I was camped on a cell with very good signal quality but very poor data rates and there weren't many people so congestion didn't seem like a factor. On investigation I found out that I was camped on 800MHz band that has limited bandwidth per operator and there was no CA.
Cell mapper, as you can see provides information about the cell you are camped on, the cell tower location, what other sectors and frequencies are there, etc.
Do you have a favorite testing app that I missed? Let me know in comments.
As I have used both these apps frequently, here is a small summary on them.As Veix and others have said, missing Network Signal Guru and Cellmapper which are the only two I use nowadays.— Peter Clarke (@PedroClarke1) June 25, 2018

I prefer using Motorola Moto Gx series phones. They are cheap, not too difficult to root (YouTube have quite a few tutorials and Google search works too) and I find that their receivers are better than others. Have detected cells that other phones cant and have even camped and speed tested on them too.10 spatial streams, 4x4 MIMO, DL-256QAM, UL-64QAM, 4-Carrier Aggregation, LAA, 80MHz of spectrum, 500Mbps in the middle of Manhattan.— Milan Milanović (@milanmilanovic) March 10, 2018
