Coverage? focuses on helping mobile bandwidth junkies find cell signal as they roam. Save time looking up coverage on the carrier's websites, compare their claims head to head and better plan your travel routing to stay connected.

** The carrier's maps in your pocket: This app contains regional level maps based off of each major carrier's data map - as found on their website at our last update. Quickly overlay the carriers you use, to create your own personalized coverage map on your device.

** No internet needed: Our proprietary coverage maps are stored within the app on your device - no downloading needed! Quickly access where you're supposed to get a signal, even when you have none.

** Urban and rural areas: Maps are at a regional level, and cover the entire continental USA, Alaska, Hawaii, Puerto Rico, and the US Virgin Islands.

** Carriers included: AT&T, Sprint, Verizon and T-Mobile

** Know where to roam: view LTE, '4G' (HSPA+), 3G, 2G and roaming areas as inclusive overlays, focus on finding the coverage type you desire.

We created this app because we are full time 'technomads' ourselves who rely on mobile data to work remotely. Keeping this app updated is a priority for us, as we depend on it ourselves!

Coverage FAQ:
Q: Why aren't the maps more detailed or released more often?
A: Our map updates require a lot of meticulous labor intensive processing. There's just no practical way to issue a new update everytime a new tower is turned on. We monitor new coverage and try to find balance between effort & staying current. This generally means at least a couple updates a year.

Q: What makes 'Coverage?' unique?
A: There are great apps out there that collect user submitted signal reports - we recommend them and use them ourselves. However, those apps are only useful in markets with an active user base. We took a different approach with Coverage? - we needed a tool to at least give us an idea of where signal should be - urban, rural, and out in the boonies. Sure, carrier maps aren't a guarantee of where signal actually is, but it sure is helpful to know which direction to head when you need it!

The original goal of Coverage is to help fellow frequent travelers keep connected and plan their routes.

The maps in 'Coverage?' are provided in partnership with Mosaik Solutions, and represent proprietary interpretations of the coverage reported by each carrier. You should not rely on the maps in Coverage to be perfectly precise or absolutely timely.

So far, map updates have been free - but to continue to support the ongoing updating and development costs, we now allow customers to subscribe to higher resolution maps that will be updated more frequently.

Coverage does not report or predict signal strength (there are great apps out there for that!). We can make no promises as to where you'll *actually* get signal.. there are too many variables - towers, device, terrain, weather, etc.

So… Got Coverage?
