The RF Signal Tracker is an engineering application for doing impromptu hand-held drive-tests with your Android phone. You can monitor the RSSI (received signal strength indication) for the phone as well as the serving cell locations, describe the cell site's zone of coverage, and save or playback that data. While many of the phone stats in the app can be displayed on the phone already (go to Settings -> About -> Status to see them). The advantage of this app is you can then map, record, and analyze those stats in a meaningful way.

App features:
- Voice notification of signal strength & technology changes, handovers, open hotspots, and more!
- Notes! Insert notes into the RF data collected. Notes can be viewed & edited in Big Picture
- 'Drive Mode' screen showing just RSSI, Cell ID, and technology to view while driving
Localized for French, Spanish, Portuguese, and German (thank you Lutz!).
- Map and record your color coded signal strength as you travel.
- War driving mode. Collect WiFi access points.
- Users can redefine site locations on the map.
