Good app. My wife and I use it to call each other while traveling internationally. We can use text and data when traveling, but not calling. We have T-Mobile. Duo uses data, so it allows us to call without extra charges and fees. We tried video calling a few times. The quality was just OK. When we used it for voice only calls, the quality was really good, indistinguishable from cell phone calls. Voice uses much less bandwidth than video. Overall, it is worth it.

One of the best video chat/messaging apps available! End-to-end encryption and lossless transfer of photos/etc. Real-time chat uses very little bandwidth for the quality of the service. Fun face-following animations to use! An image apparently must be saved to the recipient's device to be viewed with its original specifications.

Worked great in the beginning....the more updates I do....the worse it gets... The picture freezes..... And when the picture freezes the microphones cut out and you can't hear anything until the app catches up.... Very very aggravating even totally cuts you off your video call... I wish it worked like it did in the beginning...
