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!
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 every time 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.

The maps in 'Coverage?' are provided in partnership with Ookla, 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.. there are too many variables - towers, device, terrain, weather, etc.
So… Got Coverage?
Additional information about The HD Maps Subscription:
This is an auto-renewable subscription, with a duration of one year.
The subscription fee will be charged to your iTunes account upon confirmation of purchase, and will automatically renew each year unless auto-renew is turned off at least 24 hours prior to the end of the current subscription period.
Current subscriptions may not be canceled during the active subscription period; however, you can manage your subscription and/or turn off auto-renewal by visiting your iTunes Account Settings after purchase.
MAJOR UPDATE: Canadian Coverage Maps!
We’re excited to be able to offer ‘Coverage?’ in Canada, with LTE maps now available for the 3 major Canadian carriers - Bell, Telus and Rogers.
A one time unlock fee will permanently enable the Canadian maps for all three carriers inside the ‘Coverage?’ app.
For US based travelers - be sure to look up which Canadian carriers your US based plans roam onto, and enable the appropriate layers when headed north. Be sure to keep in mind any roaming restrictions or fees associated with your plan.
HD or SD Maps: If you have (or add later) the HD Maps subscription, this will apply to the Canadian maps as well - giving you access to higher resolution maps that are updated quarterly.
If you do not have the HD Maps subscription, you’ll have access to the standard resolution maps, and will receive map updates on a less frequent basis.
UPDATED: Newly updated maps for AT&T, Verizon, T-Mobile, and Sprint.
FIXED: Issues with restoring previous purchases, and other bugs.
And from the April 2020 app release:
NEW: Added maps and support for U.S. Cellular - the nation's fifth largest carrier.
TIP: US Cellular does not have native nationwide coverage, and across much of the nations US Cellular customers are actually roaming onto other carriers, and may be subject to roaming usage limits. Use our US Cellular roaming layer to get a better idea when you are out of US Cellular native coverage, and thus might be at risk of running into roaming limits.
Ratings and ReviewsSee All
Updated to HD and app crashed 100%. Fixed.
Updated subscription on iPhone 7+. Info page still says "No Subscription". Selecting "Restore Purchases" and app crashes 100% of the time. iPad version works properly. App support site doesn't let you submit a bug report so I'm doing it here.
Update: Subscription issue fixed with new update. Updating review to 4 stars. If the app support email address was easier to find it would be 5 stars.
Developer Response ,
The newest version of 'Coverage?' has an issue with restoring HD map subscriptions that for some users causes a crash. This issue only showed up in the live Appstore, not in Apple's testing environment.
We have now been able to duplicate the crash, and have submitted an update to Apple that should fix the issue. Hopefully Apple will approve it soon.
Thank you for the feedback, and we apologize for the inconvenience.
16-Aug-19: iOS 9 users, beware!
Apparently, the coverage maps provided are contained within the app, not downloaded on demand when accessing the app.
The good news: You don't need cell data or an Internet connection to look at the coverage maps.
The bad news: The maps are updated only when the app is updated. (They have added a subscription service which might change that, but most of us use this app once in a blue moon, meaning that the subscription price would just not be worth it) (Think about it: When would you use this app? Only when traveling AND when you may be considering switching cell phone service)
But that is a second piece of bad news: As of this writing (16-Aug-19), the current version of the app is for iOS 10. This means that those of us still using iPhone 4S or iPad 2 (iOS 9) are stuck with out-of-date coverage maps.
Given the structure of the app, I do not know how they could fix it, if they wanted to. I do know that, as a reference tool I might use once or twice a year, I do NOT want to get involved with a subscription service.
On the other hand, on my iPhone SE, I fully expect that the coverage maps are up-to-date.
I just have to stop using the app on iPad 2.
Developer Response ,
Remember, the app is intended for frequent travelers - such as full time RVers and boaters (which is what we - the developers - are). It's a tool in our arsenal for picking our routing & next destinations, and finding which direction to head when we have no coverage.
It was never intended for those just looking at switching carriers - but it can certainly be used that way. The free version of this app - Coverage? Lite actually fits that need better.
This is a great app I’ve used for years. I work for the cellular industry and am constantly surprised how accurate these maps are (knowing how the original source maps are created by the carrier).
The developer is regularly updating the app (thanks for X support!) and has not implemented ads or other user unfriendly things. The upgrade subscription is the only additional thing some people like me would want. I’m slowly starting to accept subscription models as developers need a consistent revenue to fund their operations.
Totally recommend for the curious and almost required for anyone in the cellular industry!
