Coverage problems? The best toolkit for improving your cellular and wifi signal.
- Signal direction
- Maps of Wi-Fi hotspots near you
- Track your spending with charts of data usage, minutes & SMS usage (beta) [NB this is why the app needs permission to access contacts and SMS, these are the permissions needed to just count calls and SMS, messages are never accessed or read!]
- Map and radar views of cell towers
- Detailed signal strength data
- Save data to SD card
- Widget
- Save wifi access points and maps of their locations by running the speed test
- Option to notify you at loss of signal (entering "deadzones")
- History of signal readings
***NOTE permissions*** to access call logs and read contacts are to help you can keep track of your plan/spending. Messages are *never accessed* just counted!
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 OpenSignalMaps.com project: we're TRUE coverage maps of cell phone networks & wifi data points freely available to all.

Supports almost all Android devices:
from small screened devices (HTC Wildifre) on 1.5 (Cupcake) up to your flashy Galaxy Nexus on 4.0 (Icecream Sandwich). We also support devices without Google APIs.
Problems? Email us!
Tips:
- 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 - comprehensive field test mode.
- Export speed test results, cell signal and wifi routers as CSV to SDCard so you can analyse as you wish.
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.
- See our website opensignalmaps.com for more detail on using the app and please add your requests for developments.
- For tablets (somde models of Xoom, Asus Transformer and others) that do not have cell radios the app will only work in wifi mode
- For devices that do not have access to google APIs OpenStreetMaps are used
- For the Galaxy S2 there is an issue reading the signal strength, this is a bug and effects all signal apps, however the app does show cell tower location as normal and works in wifi mode perfectly
- This app is developed on a Nexus One, but tested on many phones (I also have a HTC Hero still on 1.5!), let us know any problems. Sorry if we're slow in replying, but we read every email.
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, MTS, MegaFon, NTT Docomo, TIM, China Mobile, T-Mobile, SFR, I WIND, Chunwa, VIVO, BYTEL, TELCEL, Telenor and over a hundred others. Also view maps for Wi-Fi and WLAN worldwide.
(key words: opensignalmaps, opensignalmap, opensignal, open signal maps)

[2013-03-27] A Google User: Samsung Galaxy y Great App! |
|
[2013-03-27] A Google User: Good Good |
|
[2013-03-27] A Google User: Like what I see so far I really like being able to reset what tower my cell is getting it's signal from. I wish the coverage map had Sprint as a menu selection. It's hard to tell what my 3g/4G coverage is. |
|
[2013-03-27] A Google User: Good when work Sometimes broken on my note 2. It stucks at powering down |
|
[2013-03-27] A Google User: Went down from four stars... I would love to give this a better review since it has a lot of features but I have to ask, WHY do they need full access to my SMS messages with the latest update? |
|
[2013-03-27] A Google User: Ambitious, but... Update: Newest update and the song remains the same... There's something causing epic failures across multiple devices. You have to do a battery pull to recover. On a Note 2, this disaster is easily recreated. How's this okay? While it works, it's fantastic. 'll keep repeating that while I uninstall. |
|
[2013-03-26] A Google User: Nice app but... Two different Evo 4G LTE phones and Evo Shift 4G, same problems. App works fine for a day maybe, then it's nothing but force closes. The widget seems to still update data though. Love the idea, it just doesn't work. |
|
[2013-03-26] A Google User: My singals gone I click refresh for the better network on my Phone I lost my network. Pls Help what to do |

|
[2013-03-26] A Google User: OpenSignal is a must have for those in areas any distants from a cell tower or in need of a good WiFi network. I find it absolutely vital to my communication efforts. |

[2013-03-26] A Google User: Awesome Full featured..best I've seen of its kind..make my inner nerd smile. I dropped my review to 4 stars because it is eating 20% of my battery. Fix that issue and I will reinstall. |

[2013-03-25] A Google User: Convenient Like this app lots |
|
[2013-03-25] A Google User: Great app I think it would be cool if it would also make a map of cell phone services and the range of that particular tower and would give you the option to add it to g maps |
|
[2013-03-25] A Google User: Ledah |
|
[2013-03-25] A Google User: Great apps Really nice and useful |

|
[2013-03-24] A Google User: Great Does what it says |
|
[2013-03-24] A Google User: Wow We don't have to worry about slow internet anymore. This app let's you use the closest tower. It would be awesome if the app would let you type in the CID number for the tower you want. |
|
[2013-03-24] A Google User: Horrendous! Since last update this thing completely locks up and bricks my phone. I had to yank the battery and power cycle it to get my phone working again. Needless to say, the app doesn't work at all. You guys need to fix this right away or I'm uninstalling and letting this one star review stand. |
|
[2013-03-24] A Google User: Not so good. Worked for a few days then just locked up always. Uninstalled. |
|
[2013-03-24] A Google User: Cool concept but still rather glitchy Haven't tried this app in awhile and decided to try it again. Lot of cool new features but I have lg motion 4g on metroPCS and it is not showing me any cell towers I am connected to which was one of main reasons this app came in handy when I 1st tried it. |
|
[2013-03-23] A Google User: Great piece of software! |
|
[2013-03-23] A Google User: Ultimately unusable. Maps are beautiful, almost never updated, and nearly impossible to contribute to due to a pos app. |
|
[2013-03-23] A Google User: Awesome |
|
[2013-03-23] A Google User: Works Great app |

|
[2013-03-23] A Google User: What a great app. showed me the 3g to 4g lte issue with sprint. That my phone kept roaming. I test out speed. I see cell towers and where wifi signal and report the issues. Best app on the market. |
|
[2013-03-23] A Google User: Excellent Excellent app thanx |
|
[2013-03-22] A Google User: Great App. Works perfect with my EVO LTE |
|
[2013-03-22] A Google User: excellent app This app really works, I am impressed. I didn't think it was going to work, there are slot of booster out there, they say they work, they Don't, Open signal does. |
|

[2013-03-22] A Google User: Love it |
|
[2013-03-22] A Google User: It works Its OK nothing special probably won't keep it |
|
[2013-03-21] A Google User: Froze up phone Had this app a while back when it first came out and was disappointed after a month un installed just gave it another shot and it worked 10 minutes then froze up my phone re booted and now a blank screen I give up. lg Optimus g |
|
[2013-03-21] A Google User: Very good The best yet |
|
[2013-03-21] A Google User: Freezes up. On Galaxy S3, the app freezes up when set to moderate or max data sharing. |
|
[2013-03-21] A Google User: Works well That's what it's supposed to help tell where the tower is |
|
[2013-03-21] A Google User: Needs fixed Map will not fill in and show tower locations. |
|
[2013-03-21] A Google User: Awesome! A must have app! Tried the rest now get the best! |
|
[2013-03-21] A Google User: I rely on this app.... This is the best app I have found for my Nexus 10, WiFi only tablet. Recommended |
|
[2013-03-21] A Google User: Constantly crashes.... It will run once or twice then fails to launch until you wipe the cache. Real pain and no wonder Sensorly has more map data. |
|
[2013-03-21] A Google User: The new version Works alot better than the old version |
|
[2013-03-21] A Google User: Good app |
|
[2013-03-20] A Google User: Good Works well |
|
[2013-03-20] A Google User: Good, but needs Improvement I would rate it with a higher grade if it was able to show all nearby towers - regardless of the Carrier... Furthermore, I experienced some problems with the Widget! :( |
|
[2013-03-20] A Google User: Must have app This should be installed by default on every phone super ap....... |
|
[2013-03-20] A Google User: TheJuji |
|
[2013-03-20] A Google User: Very useful app |
|
[2013-03-20] A Google User: Super Supet app! |
|
[2013-03-20] A Google User: great excellent app |
|
[2013-03-20] A Google User: needs improvment It is a cool idea that I wanted to work but it is not there yet. 1) it crashes every time I use it 2) the cell tower location is never shown on map 3) the wifi location is in my house but shows many miles away, so to my neighbors wifi, maybe it is showing the ISP's node but again that should be at least in the same zip code as I am so I dont know what is up with that. I know as a fact that my neighbors are not broadcasting their wifi from the ocean! 4) I would like some tips in the program helping the user understand what the signal strength of -73 db means, is it better to be high number or low?! 5) it says there are 9 wifi around me but it shows maximum of 3 on the map only I use sprint galaxy s2 with ICS. |
|
[2013-03-20] A Google User: 5/5 Awesome! This app should come pre installed w/ every phone. |
|
[2013-03-20] A Google User: Nice app I only use the coverage map and the antennae compass but ive liked its use so far. The compass feature doesn't slew very cleanly sometimes. |
|
[2013-03-20] A Google User: Great work We use this on our tablets and phones to test wifi and cellular, for our IT business. It really helps |
|
[2013-03-20] A Google User: Cool Very nice app. Tells you where the nearest cell tower is + more. |
|
[2013-03-20] A Google User: Great but... Coverage map needs some refinement |
|
[2013-03-20] A Google User: Great app This app is super duper. Its easy to check data consumptions, wifi signals and issues, network connections and signals availability. |
|
[2013-03-20] A Google User: Great Excellent |
|
[2013-03-19] A Google User: Maps not working |

[2013-03-19] A Google User: Need to be able to move to SD card! |

|
[2013-03-19] A Google User: Great app Good to know where the T-mobile towers are, where to get the best signal. |
