Top 5 Free Calling Apps for iOS

A free calling app is the perfect way to cut down usage on your voice plan. In fact, with an app that makes internet calls, you don't even need a voice plan with your iPhone, iPod, or iPad because as long as you can reach Wi-Fi, you can make a phone call.

iOS users already have a built-in calling function called FaceTime that can make both audio and video calls for free using the internet, but it's limited to Macs and other iOS devices. Fortunately, there are plenty of really great, free calling apps that are cross-platform, meaning you can use one to call anyone else who has the app, whether they're using Android, Windows Phone, or even a computer.

Apps that make free phone calls are limited by nothing but a data connection. This means you can call someone halfway across the world or the person in the other room, and it's free either way.

Note: All of the apps listed below require a data connection, so while Wi-Fi is free, using one to call over your data plan will suck away at your data usage. If you have a severely limited data plan, please monitor your consumption and consider using these voice calling apps sparingly.
