    Love this app its very simple even people who aren't used to smartphones can use it. My only problem with this app is it literally kills my battery. A short video chat will drop my battery 40% easily that needs to be fixed in an update. I'm using Nexus 6P with Android 8.0 Full Review

    I think it is a wonderful app, I like it better then Skype and ooVoo I even like it better than Hangouts. It glitched a few times but not all that bad like it would be on Skype or something. I did have trouble with it when I left the Wi-Fi area but after I switched it to my data it works perfectly. I'm really happy that I got this app Full Review

    It's okay I wish the ringer was a bit louder or you could at least change the sound cause I would change it to something that sounds a bit more louder Update1: okay this is starting to bug me I don't like the fact that Google duo is messing with my phone's call logs it keeps adding missing calls to my phone's logs, Google Duo should have its own separate log for calls and not mess with my phone's call log. Fix it now 😡 Update 2: half of the time it doesn't let me know when someone is calling on here Full Review

    Very daft to try to compete with facetime but not allow the account on more than 1 device. Dumb. Dumb. Dumb. I like to have tablet on and still be able to use the phone, but when I am out and about I do not take the tablet. Dumb dumb Edit: friend could not even answer the call at his end. Deleting. Pointless. I will stick with skype that works on multiple devices cross platform. Dumb. Dumb. Dumb. Way to compete google. Full Review

    I wish that I could initiate voice calls from allo, contacts etc. Also I wish that there was a desktop interface. Other than that, the call and video quality is top notch. UPDATE : All gripes have been addressed! This app is amazing. Clear Full Review

    Sadly until last month I was in love with Duo but these past weeks I have not been able to make a video or a voice call. It connects with the other person but before he or she can even answer it disconnects. I have a pixel XL and have no idea why this is happening. Please help so I can give an app that I loved so much 5-stars again Full Review

    I'm shocked at the ease and quality of Google Duo! I am constantly in need of long distance communication, and thus video chat is very necessary. This is far, far better than Skype, as my family and I haven't had a connection issue yet (as opposed to Skype, where we just had to become accustomed to glitches and freezing screens/audio). I would Highly recommend this phenomenal app! Full Review

    Skype always flakes out on me and my girlfriend, but Duo worked well cross platform (iPhone and Android) and with older phone models (iPhone 4). It did all of this in better quality than Skype on our new computers. Google did a good job putting this app together in an easy-to-use, but also efficient way. Full Review

    The reason this app is so awesome is it can take someone who doesn't know Electronics such as your grandma grandpa and all they have to do is install the program and it works almost just like regular phone calling. There's no chat programs no chat Windows it just a pure video chat application. You may need to install the program for them but it's basically as easy as using your contact and clicking on that to dial. Full Review

    Bad design, it's not integrated into Android contacts, or call app. The fact I have to go to open a separate app to call is stupid. I should be able to switch from phone call to video in a click through call app! Full Review

    I've seen it advertised numerous times so I figured I'd try it out. The quality is excellent not like other free video apps I've used before. I'm definitely recommending this to all my contacts, well most of them. Lol Full Review

    Really good video call app, generally no lags if you have a decent connection. Just make sure no background apps or updates are going on as it'll definitely affect the call quality. Other than that, really great app for everyone to video call. Highly recommended. Full Review

    Ive used Duo for the first time and it seem to work out pretty good. Other than the person on the other side not being able to hear to well but could also be that im soft spoken 🙊🙉🙈 Full Review

    Hangouts is better! Google should really just market, advertise and promote HANGOUTS and scrap duo as having too many apps that do the same thing is just confusing to most people! Full Review

    Its best app for video call very simple to use. Video quality is just awesome great even unbeatable but i thought audio quality isn't good and in audio calls its worse. So kindly fix that... kindly either integrate with hangouts or replace hangouts with duo... Full Review

    Very good video and audio. Volume of sound is also excellent. Picture display and coverage angle is also good. But when a regular phone call through servive provider comes, the duo goes to mute mode. Why ?? Full Review

    I love this app for the high quality video calls. My only real gripe is that if someone has a regular phone call coming through, the video call automatically drops with no warning. Full Review

    My opinion is duo is a good video calling app but sound is the main issue. It hangs in a few minutes. So take some necessary step about it. But i must say video quality is awesome Full Review

    Peter G Published date: October 19, 2017

    Just started using. Quality so far as of Oct 19th is very good. The ONLY advantage of having an iPhone is face time. Keeps you connected. But this is the best runner up by far. Better than Skype. Want to see Google tweak this app to make it more user friendly and accessible. Face time has a real challenge now. More I use Duo I'll update the review. Who's ever interested. Full Review

    I like it. I would've put 5 stars but the quality was kinda bad and I think it would be a good idea if it will work with iOS FaceTime Instead of having to invite them and make them download it Full Review

    My only qualm with Duo us that there are added effects on top of the raw video, making me look ugly in my real skin. Otherwise, it's the best video calling app. So simple. Full Review

    Great video. Sub-par audio while on video. Especially if in an environment with loud sounds. Way to rectify this is to connect Bluetooth or headset to focus the audio Full Review

    I have used a lot of video call platforms and Duo is quite simply the best. Modern layout, excellent call quality, and the least amount of dropped calls. Duo takes a licking and just keeps beating. Full Review

    Straightforward and easy to use app. Video quality is good and switching between cameras is fast and painless. Would like to see them break away from the phone number requirement and just rely on a Google account. Full Review

    Jake Lowell Published date: October 17, 2017

    I love the app, just wish it had the messaging included like with Hangouts. Make Google Allo and duo one, and then make it like iMessage but for google, build it into every android as a default messaging app and then people will just start using it. Great video quality though like A1. Full Review
