OpenSignal - Signal Finder and 3G/4G/Wifi Coverage Maps
By OpenSignal, Inc
Open iTunes to buy and download apps.
OpenSignal is the ultimate signal toolkit that shows you how to get a better network connection instantly, find nearby free Wifi hotspots worldwide, view signal maps so that you can compare performance of networks in your area and test the speed of your mobile or Wifi connection. Unlike other apps, which look for maximum possible speed through optimized testing, OpenSignal informs you about your true speed - what you are likely to experience when normally using your phone. Anyone using the app contributes data, informing others about real-world, not estimated, mobile performance (and we'll never ask you for personal information, just your signal strength stats).
With OpenSignal you can map cellular coverage, find Wi-Fi hotspots, test and improve your reception & get faster data.
- Signal compass points you in the direction your signal is coming from
- Speed test for download, upload and latency
- Map of cell towers and Wifi hotspots
- Coverage maps allow you see the best/worst places for 2G, 3G and 4G
- Free and ad-free
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. 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 switching networks. Our wifi maps help you find local public-access wireless networks (Wifi hotspots).
Maps are not updated in real-time. Don’t worry though, we log the information you share with us to improve our coverage maps and performance 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 hotspots are in our database - we’re working on it!
- Moving in the direction of your cell tower (the signal compass) will not always improve reception due to interference effects/local geography
- Continued use of GPS running in the background can dramatically decrease battery life.
If you read to here (!) you should really join the OpenSignal beta to help us improve the app, just email firstname.lastname@example.org if you're interested.

Thanks everyone for the feedback!
I was really looking for an app that just gave me a map overlay of cell tower locations. For some reason that niche is chocked full of spam/scam apps. This app uses user collected data to build the maps I guess, so in my rural area it doesn't have a lot of information yet. Maybe in more populated areas where more people are using it you will have better results. Interface is clean, no spam, or ads so far. I'll keep it running and help contribute data.
The app seems to work OK and I'm glad they made data collection opt-in. However, it claims to anonymize the data, but there's a huge red flag that makes me doubt this: when I look at locations on the map, my location name consists of my initials and street name! I can only hope this is only appearing on my device and nobody else's. Even so, this is likely part of the data being transmitted to OpenSignal.
That's not exactly what I would consider anonymized! Deleting the app until I find this to not be the case.
Great for comparing carriers!
Great tool to objectively analyze coverage maps between carriers. The maps aren't always fully complete since it is all user generated data but it's super useful nonetheless.
