This applications allows to track GSM and WiFi network coverage by measuring signal strength and latency (ping against google.com). Client and server part are released under Apache 2.0 License, and map can be seen at http://www.neteffmon.com/
Please use carefully, it's far from being perfect.
android.permission.INTERNET : used to send ping, open http connection (measures, upload).
android.permission.ACCESS_NETWORK_STATE : used to get network status.
android.permission.ACCESS_WIFI_STATE : if wifi is enabled, we will collect SSIDs in range.
All three above are used to be able to locate the measure.
android.permission.READ_PHONE_STATE : used to get gsm signal power.
android.permission.WRITE_EXTERNAL_STORAGE : used to write produced data

App requires very little space and still provides lots of info! Runs very smooth too.
