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 wifi. 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 mobile internet? Whatsapp or BBM not working? Can't make that crucial skype call? Facebook, Instagram or Twitter too slow to be enjoyable? Run a speedtest to see the real speed of your connection, use the signal booster compass to get a better connection or use our maps to find the nearest free wifi!
Best of all, every time you use the app you're helping to improve it! By helping us to expand our wifi 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 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 hard to make sure the data you contribute to the project is available to everyone as quickly as possible.

- Not all towers and wireless routers are in our database - 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 tower locations will improve.
- 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
We map- Coverage and Speed tests for Verizon, Sprint, Vodafone, EE, AT&T, O2, 3, TIM, T-Mobile, Telcel, I WInd, SFR, Wifi and more
It should be helpful for all the people who mount sector antennas (f.e. GSM sector antennas).

Please note: This app does not allow you to watch TV on your phone. Instead, it uses your location to find nearby over-the-air Digitial TV (DTV) and HDTV signals in the *United States* and assists you choosing an antenna and pointing it in the correct direction. Information provided by the app includes: TV channel signal strengths, compass bearings to signals (direction), distance to signal towers, TV channel numbers, RF channel numbers, elevation, and frequency bands (UHV, Hi-V, Lo-V).
User location is determined automatically via GPS or the network. Alternatively, a location can be manually entered. DTV/HDTV station data is downloaded from the U.S. Federal Communications Commission (FCC). The app displays nearby TV signal information in three ways:
1) A scrollable list displaying all nearby TV signals ordered from strongest to weakest.
2) A compass that displays the stations at their correct heading from the current location.
3) A map displaying the current location and the location of all nearby TV signal towers.
The app can also be used to recommend antennas for your location.
Keywords: Antenna, Television, TV, Digital TV, DTV, High Definition, HD, Hi-Def, HDTV, Signals, Over-the-air, FCC, Channels
Practical if you are the DIY type or if you are visiting a camping site in any of the supported countries and need help for your TV antenna.
Please note that the application calculates the signal strength and direction based on the location of the transmitters and your mobile phone only. Obstacles between you and the transmitter (buildings, hills) which can disturb the signal availability are not taken into account.
If you want to change country swipe up or down.
This app has transmitter information for the following countries:
- United Kingdom
Don't see your country represented here or just have information on transmitters? Please contact me and I will see if I can add more countries to the list.
Simply type in the frequency in megahertz for the antenna you are building or adjusting and let AntennaCalc work out the 1/4 wave, 1/2 wave, 5/8 wave and 1/1 wavelength values for you.
Results can be displayed in meters (m) or feet (ft).
Radio amateurs, CB radio / freebanders and radio professionals will all find this app useful.

- If a site appears off the coast of Africa it means that you are using Google's location service or OpenCellID and they cannot determine that cell's location (so it returns the location 0 deg Lat, 0 deg Lon). A new feature for version 2.2.9 is the ability to define your own site locations (add, move or remove) by pressing a spot on the map or a site icon. Users can do their own site surveys as they travel. This is a workaround for those who do not have access to site location data -- unless you are an engineer for a carrier, you won't have access to this data since site locations are generally considered proprietary.
- Background recording, where you exit the app after you start recording, will not register signal strength changes if the phone is in sleep mode (screen is blank). This is a "bug" in Android not the app. If the phone is not allowed to sleep, background recording is possible.
- BER, EVDO, SNR & Ec/Io may display -1. This is the number the Android OS is sending, sorry.
- The app is optimized for GSM service. CDMA devices are not completely supported. This is due to the lack of a CDMA phone (and contract) on my part, not anything specific to the technology. So if you have a CDMA phone be aware it has not been tested by me.
- Please remember you are using a phone, not a laptop. If you try to record hours worth of data, and/or play it back, unexpected things may happen.
Satellite Director replaces all of that. See tips to success below !!!
Just enable the GPS in your phone or enter your GPS location, select the desired TV satellite and point your phone to the sky to target (find) the TV satellite. You have found the satellite when the white ball is in the white circle and the cyan ball is in the cyan circle. Align, in azimuth, the offset arm of the satellite dish to the cyan arrow on the phones display and the satellite dish is aligned in azimuth with the satellite.
Selectable audio tone, camera preview, continuous mode (no pause), color pickers or a user defined satellite position may make it easier for you to find the desired TV satellite.
The satellite list contains 280 satellites.
Optional you can take a photo (resized)/screenshot by touching on the director tab. The photo/screenshot is ONLY stored on the phones memory card.
Optional: you can get an indication when you are to close to iron (dish/pole) in the form of an green/yellow/red bar.
Warning: The compass of your phone can get inaccurate because it is affected by magnetic fields or because it is weakened by age. Calibrating the compass may not help.
This app is add-free!
Satellite positions are derived from Agi's database. Some positions may seem not accurate (example: Hispasat 30°w is at 29.96°w in the satellite list) but they are very accurate.
New phones with Android 4: in case of a wrong compass reading the "Settings" screen has options to correct the compass readings !!!!
The market page may state this app is compatible with your device but I have learned that that is not always the case. The only sensor you need is orientation (compass). Use app "Sensor List" to verify that your device has it.
PRECISION DEPENDS ON THE QUALITY OF YOUR HARDWARE.
Metal objects can cause interferences.
Previous versions avialable from my website.
If you have any questions or problems PLEASE write an email. It's NOT possible to respond to the reviews!

3 tips to success:
1- do NOT go to close to the iron dish, lnb arm or pole (keep at least 30 cm distance)
2- calibrate the compass of the phone by waving it in a figure 8 before you start
3- optional: calibrate the compass of the phone by rolling your phone along its length axis about 2-3 turns (works on some phones)
** This app is intended for Android v1.6 (Donut) using GSM only. v2.x users need RF Signal Tracker (Eclair).
- Record, save & playback rssi data. See HO stats.
- Vibe & sound on Handoff.
- Show coverage bubbles of serving cells.
- Users can upload their own site locations.
