Long ago, the hosts of this website (myself and Chris) wrote a little mobile app called Coverage?
We generate coverage maps based on the carrier's own maps, bringing them onto your mobile device into an overlayable format. This allows travelers such as us RVers to better plan our routes and stops to be within coverage of our chosen carriers.
Every quarter we issue a free update to the app for our customers updating the maps.
Just this morning, Apple approved our February update to the app. It's now available in the Updates section of the App Store for downloading.
In particular, T-Mobile maps are better than ever before. Their new mapping system still doesn't visually separate out 3G, 4G and LTE from each other. But since they claim they've rolled out LTE in most markets, we're now reporting all 3G/4G/LTE as a single image for all three coverage layer types. Which means.. no more stars (which we previously used to indicate markets where they claim LTE). It's not as precise as we'd prefer to match how the other carriers report their coverage, but - we'll continue to do the best we can with the information available.
Also, the app updated brings support for iPhone 6 and 6+ screen resolutions.
Eventually, when we have some free time, we'll re-write the app in such a way that will allow us to port it to Android and support both platforms. For now however, the app remains iOS only for iPhone and iPad.
Don't have Coverage? on your iDevice? Get it today in the App Store for just $2.99. It was created specifically for us for our fellow RVers needing to keep connected across the nation.
We've also updated all of the map previews for each carrier on our Which Carrier is Best for RVers? article with maps from current version of the app.
