4 stars: Great app, brief pixelated moments with a bit of lag when long distance video call between Queensland, Australia to Adelaide, South Australia and that's with a premium carrier over 2400 km apart but overall not much really to complain about also quite good on the data usage I think. Awesome!
5 stars: Works great between android and iOS. The video quality is as good as can be expected. The only issue, if you can even call it that, is the voice is kinda low for outdoor or noisy setting but that is really not even a complaint, just a comment. Bottom line, I love it!!!
5 stars: I've used multiple apps to videochat before but honestly Duo has the best connection. Less chance of dropping calls, more chance of getting through. The only downside is that it eats up your battery quickly, so you constantly have to plug in the phone. Other than that, I love it! Best way to communicate with my family long-distance.
5 stars: I like this App, because it gives me the opportunity to view whom I am talking to. However I do have one small complaint. That is to say, that there is interference with the sound, whereas when a person speaks to another person there's slight delay before the sound is relayed to the other person. Other than that, the 5-star rating still applies. But please correct the issue. Thank you very much.
5 stars: Better than anything else I have seen out there. Yes loses videooccasionally but they all do that. Most also have audio issues but this one do...
