What's New

Complete map update for all carriers in the continental US.. and a spiffy new icon!

- All carriers seem to be slowing down on expanding markets. Not as much new coverage reported as with previous updates - we may adjust our update cycle accordingly. (We promise *at least* quarterly updates... more recently they have been every other month.)

- Some carriers are starting to roll-out various flavors of 'advanced' LTE. We are also keeping an eye on this. Currently, only Sprint shows their Spark markets on their maps - but yet no device that can run Coverage? is Spark capable.

- T-Mobile continues to not graphically report their LTE markets at regional levels on their maps - so we continue to manually add in purple stars in markets they have announced LTE roll-outs. Sorry folks, that's the best we can do - we can only report what the carriers do.

As always, these FREE updates are funded entirely by new app sales. We appreciate you keeping your reviews in the App Store fresh (they reset with every update) and telling your friends about Coverage? Thank you!

App Description

Directly overlay and compare cellular carrier coverage maps! Perfect for travelers - research where you're covered across the USA!

** Follow our Facebook page to get update alerts: http://www.facebook.com/CoverageMapApp **

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 maps based off of each major carrier's data map - as found on their websites. 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+ & WiMax), 3G, 2G and roaming areas as inclusive overlays, focus on finding the coverage type you desire. (Hint: T-Mobile does not graphically distinguish between 3G/4G/LTE on their own regional maps. Thus we manually insert dark purple stars to at least indicate their LTE markets.)

Check http://www.twostepsbeyond.com/apps/coverage for a quick video demo. We created this app because we are full time RVers ('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. The carriers are all rapidly rolling out new coverage and 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. Updates generally are issued every 7-10 weeks.

Q: What makes 'Coverage?' unique?
A: There are great apps out there that collect user submitted signal reports - we love them. 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. Some have also found the app useful for shopping for their best carrier, even though our maps are regional - not neighborhood level detailed.

The maps in Coverage are our own 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, though we intend to update them at least quarterly. So far, map updates have been free - we may at some point offer more frequently released higher res maps via in app purchase.

Coverage does not report, collect 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?
