Apple's FaceTime service allows for basic two-way video calling and ships with every iPad. Users looking for more advanced video calling with additional features and multi-party support might gravitate toward ooVoo. The video chatting app is free and available in the App Store for download on the iPad.

OoVoo on the iPad

The ooVoo app enables you to video chat with up to 12 friends at once while displaying up to four simultaneously on screen. All of them have to be ooVoo users for the video chat to function. To initiate a video call, search for friends within the app and tap those you want to invite, then tap "Go." To add new friends on ooVoo, tap the Add Friends icon on the top right.

While the focus of ooVoo is video chatting, you can also choose to simply initialize an audio-only call or an instant message conversation. Combining these is possible too; for instance, you could instant message while the call is taking place and share your device's screen with participants. Tapping the Paintbrush icon during a video call lets you unleash some fun creativity on your friend's faces in the form of digital art.

For $29.99 per year, you can upgrade to ooVoo Premium to remove ads and get priority support.
