What's New

All carrier maps completely refreshed and updated for the entire USA. AT&T, Sprint and T-Mobile all continue to turn on new LTE markets, while Verizon seems to be slowing down.

We continue to manually mark T-Mobile LTE markets with a purple star, as their own maps don't visually make a distinction between 3G/HSPA+/LTE at regional zoom levels.

4G Finder has also been optimized for the new 64-bit A7 processors found in the iPhone 5S, iPad Air and Retina iPad Mini.

As usual, your reviews in the App Store and telling your friends about the Coverage? line of apps (including 4G Finder & LTE Finder) help us reach new customers. These free & frequent map updates are entirely funded by new sales of the full version of this app - Coverage?. We greatly appreciate your support & enthusiasm!

App Description

'4G Finder' is a special free 4G-only version of our hit app 'Coverage?' intended to provide travelers with a powerful tool for tracking down the nearest fastest bandwidth.

'4G Finder' provides an at-a-glance, "universal", area overview, cellular 4G coverage map by interactively overlaying the major USA cellular providers. 4G is defined by whatever the carrier is calling 4G and can include LTE, HSPA+ and WiMax. For AT&T, their LTE network is displayed as a slightly darker blue than their HSPA+ network.

'4G Finder' focuses on helping bandwidth junkies know where they might be able to get their next hit, no matter what network (or combination of networks) they use.

** Know before you go: Avoid having to check each provider's coverage map individually to know where you're most likely able to keep connected in your travels.

** No internet needed: All coverage maps are stored locally, so you can check where coverage is most likely even when you have none.

Like 4G Finder and want all the coverage types and more frequent updates? Get our full app, Coverage? - It includes layers for LTE, 4G, 3G, 2G and roaming of all major carriers, and has additional features including search ability.


Q: Why aren't the maps more detailed?
A: We can only include so much map detail in an app small enough to be downloaded wirelessly!

Q: What makes '4G Finder' unique?
A: There is no other tool out there that allows you to overlay coverage maps from all the major carriers. We have done the labor intensive work to create aligned, standardized interpretations of each carrier's reported coverage. For travelers who have devices on multiple networks who need to stay connected as they roam, this information is essential. Unlike checking individual carrier websites, 4G Finder is fast and easy, and it works even when you have a slow connection, or none at all.


Note that the maps in 4G Finder are our own proprietary interpretations of the coverage reported by each carrier. You should not rely on the maps in 4G Finder to be perfectly precise or comprehensively up to date, though we intend to periodically update them. (We do keep the full Coverage? app updated more often).

We can of course make no promises as to where you'll *actually* get signal. The goal of 4G Finder is to give you an indication of where you're most likely to catch a wave, not provide neighborhood level precision.

So… Got Coverage?
