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)

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.

by A Google User the 3/27/2013

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?

by A Google User the 3/27/2013

Good when work Sometimes broken on my note 2. It stucks at powering down

by A Google User the 3/27/2013

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.

Good Good

Samsung Galaxy y Great App!

Long overdue Very much needed independent check on self serving maps provided by carriers. Finally some real data! Please download to improve the data further.

by A Google User the 3/26/2013

It's a beauty!!!! I like it!!!! It haves everything you need to know.

by A Google User the 3/26/2013

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.

by A Google User the 3/26/2013
