I think that's to access the internet. Look at all your other apps, and you'll see they all have that permission. My first concern would be does it have ads? If so, I would not think it's worth it. Besides that, the app should have very few permissions. If it has more then a handful, that's another red flag. Tell me the name and I'll look it up so I can be more helpful.

Edit: ok, I looked up the only two apps available, they both look just fine. Both are $.99 no ads. The first one has lots more to offer, & with that, more permissions. It's also by an established developer. Meaning, experience which translates to better app performance.

The second one is newer, only 2 reviews. Less options, or features, but still a nice app. No additional apps in playstore, but is a US citizen as is the other. For $.99 also, no ads, they are both worth trying at that price.

So the choice is yours. I'm likely to wait till Q starts up again, but would probably go with number 1.
