Coverage is a superb, single-purpose app for the iPad and iPhone. Its single purpose, as the name implies, is to compare carrier coverage in the USA. It shows you 4G and LTE coverage and more for each of the four major US carriers (AT&T, Verizon, Sprint, and T-Mobile).
Here’s a little more background, via the App Store page for it:
The only app that directly overlays and compares carrier coverage maps! Perfect for travelers – research where you’re covered across the USA!
Coverage provides an at-a-glance, “universal” cellular data coverage map by interactively overlaying maps from major US cellular providers.
It focuses on helping mobile bandwidth junkies know where carriers claim they might get their next hit.
** Know before you go: Coverage has standardized each major carrier’s data map so they can be easily overlayed, creating a personalized coverage map of major carriers you travel with.
** No internet needed: Our proprietary coverage maps are stored locally; check where coverage is most likely even when you have none. (The underlaying maps require internet/caching.)
** Urban and rural areas: Maps cover the entire continental USA, Alaska, Hawaii, Puerto Rico, and the US Virgin Islands at a regional level.
** Carriers included at higher-res: AT&T, Sprint, Verizon & lower res: 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 need. (Hint: If your device indicates ’4G’ – it may be HSPA+/WiMax not just LTE. For AT&T and Sprint customers, use the “4G” setting to see both.)
I only just discovered and tried out the app today, but I’m already well impressed with it. It’s a simple, map-based app that lets you drill down to your home town or state (or any other area of interest in the US) and see how the coverage map looks for any of the four big carriers – for 2G, 3G, 4G, and LTE.
For instance, I can look at just AT&T’s LTE coverage in my hometown of Austin – as shown in the screenshot at the top of this post. Or I can look at AT&T and Verizon’s LTE coverage overlaid on the map:
This is one of those great apps that just does what it says on the box, but does it really well – and it’s a pleasure to use.
I can think of a number of good uses for this app for iPad and iPhone owners. Just for starters, it will definitely be helpful if you’re tying to decide which carrier to go with on a new device, or when thinking about a switch to a new carrier. It should also be a great tool if you’re taking a trip and want to see whether coverage is good enough where you’re going to make it worthwhile to pay for a month’s data plan on the iPad. It might also help you highlight any issues your own iPad might have with connecting if it shows you strong coverage in an area where your iPad is having difficulties.
Here’s the app’s icon, just so you can spot it more easily in an App Store search:
And here’s an App Store link for Coverage; it’s priced at $2.99 and is a universal app designed for both iPad and iPhone.
