Android App for mapping Cell Towers/Cells without Wifi/Internet Connection

[techskept]

Hey everyone,

First time posting here, so please be gentle.

So I'm looking for an app that allows me to map the location of cell towers and cells that doesn't require a Wifi or Internet connection, and export these cell locations to a .csv/.kml file.

All of the apps I've tested have required a data connection to get the latitude and longitude coordinates, but I'm looking at performing the analysis in an area of limited connectivity.

I'll be using a set of Samsung Galaxy S5 phones.

Thank you, and any help offered has my gratitude!
