The best toolkit for improving your cellular and wifi signal. Over 1m downloads!

- Signal direction
- Signal graph
- Map and radar views of cell towers & WiFi routers
- Detailed signal strength data
- Save data to SD card
- Widget (in beta!)
- Save wifi access points and maps of their locations by running the speed test
- History of signal readings

The simplest tactic to improve your reception is to walk in the direction of your signal. Not foolproof, but worth a shot!

Option to contribute to the project: we're TRUE coverage maps of cell phone networks & wifi data points freely available to all.

Problems? Email us!

- Click the wifi-cells toggle button on the bottom left to see wifi routers
- Use wifi and GPS for best speed and accuracy
- Verizon & Sprint users will see only one connected tower at a time
- Not all towers and wireless routers are in our database. Sorry!
- Moving in the direction of your cell tower will not always improve reception due to interference effects and local geography.
- Data is mainly crowd sourced - wireless and antenna locations are calculated by triangulation. This means they are not exact, and sometimes they may be way off. As more people use this app the data will improve.
- Click on the "i" on the overview screen to see more signal stats - including signal RSSI in ASU and dBm

Advanced notes:
- For GSM, cell tower are identified via cell id and location area code (CID and LAC)
- For CDMA, cell towers are identified via Network ID, Base sub-station ID and system ID (NID, BSSID and SID)
- See our website for more detail on using the app and please add your requests for developments.

We're building trustworthy and comprehensive coverage maps for GSM, CDMA; for 2G, 3G & 4G. We think this is the best signal tool you can find, let us know if you think anything is missing.

Networks we're mapping: Orange, Vodafone, O2, 3, AT&T, Sprint, Verizon, Movistar, Claro. And over a hundred others.

Scott L. Motorola Droid 4 This a great app. My employment has me all over the place. Now I can maxiumize signal strength before I place or anaswer a call. It has eliminated a LOT of dropped calls and some of the frustration that comes with it. Functional and easy to use. Kudus to the developers of this app.

Not working that well like before It work great on old phone got new phone and it doesn't work keeps force closing.

by A Google User the 1/28/2013

Great concept I have a very well optimized phone rooted for performance but not over clocked. This program works when first installed but after installation it freezes even opening it a day later. When it's working, everything in the program works as far as stats for all networks, better signal direction. Fix the bugs and this will work great.
