Help contribute to our crowdsourced impartial maps of carrier coverage and wireless hotspots by using our app to improve your connection.
Based on our community-generated data we are able to help keep you better connected by giving you a practical solution to the problems of slow mobile internet and dropped calls. Simply follow our signal compass to walk towards better phone signal or see our in-app coverage maps to work out which carrier is best for where you are, useful if you're thinking about changing. Our wifi maps help you find local public-access wireless networks (WAPs), helpful if you're travelling abroad or just want to find a local cafe with free Wi-Fi. Our Stats tab helps you to keep track of your usage, so there’s no danger of you going over your plan limit on data, voice or text. (NB – this is why the app needs permission to access contacts and SMS, these are the permissions needed to count calls and texts, messages are never accessed or read!). Slow/fast mobile internet? Run a speedtest to see the real speed of your connection.
Best of all, every time you use the app you're helping to improve it! By helping us to expand our Wi-Fi database and improve our coverage maps you're making the app work better and everyone else who uses it.
The best tactic for getting better signal is to follow the signal compass.
Maps are not updated in real-time. Don’t worry though, we log all the information you share with us to improve our coverage maps and signal information. We’re working as hard as we can to make sure the data you contribute to the project is available to everyone as quickly as possible.

Tips:
- Not all towers and wireless routers are in our database. But we’re working on it!
- Use Wi-Fi and GPS for best speed and accuracy
- Verizon & Sprint users will see only one connected tower at a time
- Moving in the direction of your cell tower will not always improve reception due to interference effects/local geography.
- Data is crowd sourced - wireless and antenna locations are calculated by triangulation. As more people use the app the tower locations will improve.
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). CDMA phones include the Droid (II, X, HD, etc), EVO 4G - all phones on Verizon and Sprint.
- For tablets (some models of Xoom, Asus Transformer and others) that do not have cell radios the app will only work in wifi mode
