    Best video calling app ever. But for some reason when I am calling from my Airtel number. Other party doesn't receive my calls most of the time. Despite us both having good connectivity. Same doesn't happen on Jio and Vodafone. Kindly look into this. I think Airtel is blocking services to this app. And reduce the bandwidth consumption. It consumes way to much data. Full Review

    I think the application for the phone is good, but I've been having a few issues with the application. For one, I cannot receive calls from another person trying to call me through the app until I open the application and another problem is that it keeps cutting video off even if I have good reception and the other person on the line having good connection too. But my main issue is the first one, I cannot receive call or notifications until I open the application. But other then that I give it 4 stars for the video quality and simplicity. Full Review

    The app is good. When it works the audio/video quality is clear. It sometimes won't connect my calls giving a camera error, once I reset my phone it resolves. There are times when the video quality is poor and I can't see who I'm calling. I don't use it as much anymore. I'm going to start using it again to see if these issues have been fixed. Overall I like this app. Full Review

    Very awasome also useful app. It provides calling although the other user didn't have the app installed. Just 1 issue is that its ringtone when someone calls us is too low although at full volume. Plz fix this or make it user choice ringtone option so we can easily other ringtone as well. Thanks Full Review

    Blown away at the quality, I've used a few similar video chat apps and this one takes the cake by a huge margin. Slow connection or not, app performance is flawless, my kids love that they can see mommy when they call her, great job Google, as always, keep doing the amazing work u do Full Review

    It has super good quality but the one thing is... You have to have a good phone that has good quality so like if I call a friend and he's using Samsung 6 the quality will be bad so it depends on the type of camera and phone generation like the iPhone 7 and up or the Samsung 7 and up those have good quality but everything else is in perfect place 5/5 stars super good communicating and super good quality.

    Love this app. I have a Samsung and my wife has an iPhone so we're able to use the app to video chat with each other. Plus the quality on regular phone calls is fantastic. We generally have poor service and dead spots in our home. This app fixed all that for us. Full Review

    It's very hi-fi quality call. The only thing is it doesn't connect with Bluetooth Bose revolve plus.. can you suggest why it is so. If the vedio or voice call can be taken with my Bluetooth speaker then this app is the best. Full Review

    Not cross compatible with iOS. Tried using with two of my brothers...both have iPhones. Both of them complained that they were hearing a bad echo of their voice, and I could only hear a portion of what they were saying. Video quality was above average...all my issues have to do with audio. Please work with iOS compatibility. Full Review

    The quality should be fixed a little bit but the sound quality is better then an actual phone call which is suprising. Overall love the app , keep it coming with better quality of video especially for android users as I have the s7 and the image on video chat comes pixelated still so that needs to be improved. Love it still tho!! Gonna use it daily. Full Review

    I'm the only one in my house with an Android based phone, so being able to "facetime " with all of them without having to get Skype on everyone's phones and create accounts etc... is so nice. And it happens to work great. Full Review

    This app for me has really got a lot worse since november or so. Lots of weird intrusive noise in the background. Unstable. Not optimised well for slow connections? Whatsapp voice calling does a better job if you want to actually have a conversation without being distracted by delays, cut outs and feedback loops. Full Review

    It still has it's kinks, blurriness, drains the battery quickly, poor sound quality. Yet, it is the equivalent of Face time but it gives access to video chat from different types of phones (i.e. iPhone to Android and in reverse) Full Review

    Android system gives me an incorrect error about lack of storage space when I use the power and down volume buttons to take a screenshot while using Duo. Does not give me an error message if I hold down the home button and have Google assistant take a screenshot with the "share screenshot" option.... also drains my Nexus 6p battery quickly. Even quick charging can't keep up with Duo during a video call... Full Review

    Awesome clarity in both picture and soundquality and so easy to use my 4 year old son figured it out without previous instructions. Would be fantastic to be able to use on a device without the need of a phone number except for the one tied to your Google account. Tablet/old phone for the kids etc Full Review

    Rating the app itself gets a five star for what it is intended to do. Google's messaging strategy, however, gets a one. Breaking the functions of Hangouts into three separate apps frustrates me as a user. I'd prefer that Google did a ground up rebuild of the functions that needed improving in Hangouts, like the video call reliability and quality. Full Review

    As much as my best friend and I wanted to wash our hands of Google and their band of mismatch group of messaging and video call apps, this is the best we've ever seen at maintaining good call quality. No matter what the circumstances it doesn't skip a beat. Full Review

    Doesn't work for tablets? But apple manages to make a Mac, iPhone and iPad all ring simultaneously with just your iPhone's number. Come on Google fix this please. Add the ability to be reached at multiple numbers or Gmail accounts and this would be perfect Full Review

    Hands down the best video app. Works across phone brands and even works on Apple phones (which my wife absolutely had to have). Allows us to keep in touch when I'm away for business. Thank you, Google, for developing this! Full Review

    One thing really nice about it is that I cannot change ringtone. I usually keep rings at single beep, but thanks to the team working on Google Duo, now I get a loud obnoxious ring during the meetings and quite a few times when I am sleeping and there is no way to change it. Rocket science, right? Full Review

    With Skype if both parties talk at once I find that the audio gets cut off. It makes for an unnatural conversation. With Duo you can talk over each other and the audio stays normal. Picture quality is good too. However I've only had one conversation on it so my experience is limited. Full Review

    Pratheepan Thevadasan Published date: January 13, 2018

    I think the app is good for video calls etc.. but it's not a replacement for Skype. Tying the account to a mobile handset limits it's full potential. It would be good if duo can be supported via web (not like WhatsApp web) and other platforms similar to Skype's reach. Although this goes against what duo is, if you do video chat with multiple people, and selective auto answer then this would be great for the elderly. Full Review
