Coverage FAQ:
Q: What's the difference between Coverage? and Coverage? Lite?
A: Coverage? Lite allows users to view maps from a single carrier (after a trial period with all carriers), and can be unlocked to include all of the features of Coverage?

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.

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!

"this app can be indispensable" -


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.

Ongoing map updates have been free - but to support the ongoing 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

So… Got Coverage?

How does it work?

I saw one review saying it worked well. I don't understand.😥 it's a great idea though. For that I'll give it a 4.

07-Sep-19 - Correction

Not clear in the product description is what the "trial period" is.

On a "splash screen," the first time you use "Coverage? Lite," you are told it's THREE USES.

For those three uses, you get the full "Coverage?" After that, the product description tells you that many (most?) of its features will "lock up."

Bottom line: Based upon your needs, it may be worth your while to go straight to the $2.99 version of "Coverage?" and skip "Coverage? Lite."

Good about this app is that the prices are clearly labeled: $2.99 for "Coverage?", and that's a one-time fee. They list $5.99 and $4.99 per year for the annual subscription. I suspect the $4.99 is the discount mentioned on the splash screen if you first pay $2.99 to "unlock" the app. Those with the annual subscription can expect to get updated maps more often (and in HD).

So, what you need to decide is, just how are you going to use "Coverage?"?

First, I would say that, as a one-time fee, the $2.99 is reasonable. The subscription fee is a more difficult thing to process.

It would come down to just how you plan to use this app.

For me, I use the app only when I'm thinking of shopping around for a new cell phone carrier. I might also check it when traveling, especially to places like Arizona, Nebraska, and Nevada, where some of the major carriers don't always have good coverage. It's a good "heads up."

I imagine that if I lived in an RV and traveled all the time, especially to highly rural areas of the west, the subscription service would be a better idea.

That's just my thought process. What is yours?

Corrections: I deleted much of my 02-Sep-19 review since it was based upon my bad memory. In particular, I thought I got "Coverage?" for free. The author states that "Coverage?" has never been free. If that's the case, then "Coverage? Lite" may be a good way to look at the "paid for" app.

I only upgraded from two to three stars, though, because I really don't like the concept of "crippleware," software that lets you use it a limited number of times before it "locks up" and isn't that useful anymore. And in this case, the stated "three uses" would seem to make the "Coverage? Lite" app shut down in a very short time; as I guessed above, maybe less than one day.

Developer Response ,

Actually, Coverage? (the $2.99) paid version was released first back in 2010 and has ALWAYS been a paid app - long before app upgrades and in app purchases were a thing.

Original Coverage? customers continued to get free updates for years - and continue to do so.

We released the HD Map edition about 2 years ago for those who desire higher resolution maps - and so we could create residual income from the app to continue to afford to even offer it. Remember, our intention with the app is for frequent travelers to help in their planning, which is who the subscription is aimed at.

We used to also have LTE Finder, which only showed the LTE coverage of the carriers - this was the free version that you might have downloaded way back then.. Well, times have changes and most carriers coverage maps are solidly LTE - so it wasn't all that different than the paid Coverage? version. So we needed to adjust the model. We renamed it Coverage? Lite - and you get to use the full app for free 3 times. Then you can pick a single carrier and continue using it for free. For those with one carrier - this is still quite useful.
