CatchApp.

Basically Catch App allows you to call anywhere, be it directly to a landline, someone who doesn’t have a data capable phone, even another continent. But here’s the catch, you can call all these places at the exact same rate as you would someone standing right outside your doorstep. We even give your very own cell number, they can call you back on. No SIM swap needed. Just download the app and presto. Now that’s innovative.
CatchApp does not upload users contacts to our server or to any third party services. It only requests permission to access contacts so that it will be easier for the user to make calls.
