Al igual que Google se puede agarrar en todos lados y es muy útil para la gente que no tiene teléfono de manzana (que son carísimas) este se puede poner al igual que Google en cualquier teléfono inteligente. Me es muy útil y tiene excelente calidad

Great for hearing impaired because I can lip read. Thank you!

I love duo and the call quality is better than that of FaceTime from what I’ve experienced but it overheats my phone like no app I’ve ever used. Maybe this is just a me problems but whenever I use the app for any longer than 15 minutes my phone become boiling hot and sometimes disables use due to the temperature.
Satisfied customer!!
Annie Banie on 2/13/2018
The picture and sound quality has been great every time I’ve used Duo. I’m very satisfied with this app!
Pretty Good App
Laverne904 on 2/13/2018
Picture quality and voice is normally clear. It does eat battery and video sometimes freezes.
So much better than FB messenger
L.A.C.E818 on 2/13/2018
Love that it’s much more clearer than when I use FB messenger. Sometimes clearer when I even use FaceTime on my iPhone in certain spots. Good quality overall. Worth the download
Silkdress on 2/13/2018
Google Duo puts me closer to the ones I love. The clarity of picture and sound is amazing!!!!!

About video
Angelskietta on 2/11/2018
It was good quality but stilll sometimes blurring and freeze not bad. It was not like FaceTime because FaceTime got easy blurring and freeze, take a long problem. Duo was blurring and a little freeze but still can see clear a little blurring still good see little clear. It was worth. So need a little more improve but do not too much change okay. Just a little add more clear at all 👌🏽
Works well!
themom1982 on 2/11/2018
Duo works very well. Excellent video quality only my iPhone gets quite hot when using.
Almost perfect
D………. on 2/11/2018
i want to be able to see myself in the bubble completely while seeing other person like in the square on facetime and even better if was split screen like on skype. right now that little bubble doesnt show enough call/video quality is just a tad lower than facetime but pretty awesome. i wish there was a way to integrate into ios lockscreen so it looks more like a normal incoming call and not a notification. hope google gives us some of these updates. thx!
Still no update for volume control????
Purelife26 on 2/11/2018
It’s been months since the IOS 10 has hit and Duo doesn’t seem to work with it. I can’t adjust the volume during calls so it’s just loud as hell..
Good but...
Markena7 on 2/10/2018
Google duo is a good way to communicate with android users but you can’t adjust the volume! Everyone can hear your conversation unless you connect to Bluetooth or headphones... hopefully they fix this issue

Ringtone issues
Nelsole on 2/10/2018
I love this app but I’m very frustrated with the ringtone. I have missed more calls because I don’t hear it. You can change the volume or the ringtone in iPhone!
Sss 82 on 2/9/2018

godessofswag on 2/9/2018

Better than FaceTime
wethejordan on 2/9/2018
My mom recently switched to droid and we found this app to continue our video calls & they’re much better: - clearer call quality - better picture - better sound * needs support for iPhone X

Unable to mute
NotNewtonsApple on 2/8/2018
If I get a duo call, the phone starts vibrating and I cannot stop it. I’ve tried pressing the power button, volume buttons, nothing. I have to open the app and decline, which is really hard if you’re in a meeting or driving with the phone in your pockets. Fix it, will ya?
Getting better
Jenthebarber on 2/8/2018
Works good 80% of the time, sometimes picture is pixely and freezes.
Better then FaceTime
Tawfek on 2/7/2018
It has better reception and the picture quality is better then FaceTime.

Google Duo works like a charm. I downloaded it so that I could attempt a video chat with relatives, and having a previously failed attempt with a competing video-calling app, I was initially skeptical. But much to my (pleasant) surprise, it worked beautifully! If you're looking for a video-calling app that works, stop here. This is the one. Hey, 38k+ reviews for 4.5 stars can't go wrong.
Fix the volume controls!
HelloLondon:) on 2/6/2018
Why can’t I change the volume??? The buttons say they are changing but nothing happens. My boyfriend has a loud voice! Gah! Help a girl out, Google!
The best thing
Puncher34 on 2/6/2018
I love this app especially for communicating with Samsung/android
Good except...
Flaco Mosco on 2/5/2018
I love this app it’s really great but can you make a group video chat? I don’t think u can but other than that the app is amazing I love the high quality video and how easy it is to call someone! Better than FaceTime
Good thing about google duo

Wil 2210 on 2/5/2018
I love this app it’s a way to connect with others
Battery usage
KiyokoKira1 on 2/5/2018
This app drains my battery so fast to the point where I’m not able to finish a conversation with my friends. Me and my husband has been using this app for a year now and please get this issue fixed it frustrates us so much.
Nathaly281 on 2/4/2018
I love how this app works. It is extremely easy to use and it works for both audio or phone calls, which is great. However, it drains my iPhone’s battery extremely fast. During my most recent use, my phone went from 28 to 8 percent in a 5 min video call. This hasn’t been the first time it’s happened. I find myself needing continuous charging to use this app. It drains faster than Snapchat! Hope this can get fixed.
Mad about the screen quality
NiallsBunny69 on 2/4/2018
The best video & calling app!
Bardabe on 2/4/2018
I use to use WhatsApp to call my girlfriend when she’s working internationally and the quality was meh. Duo has been AWESOME haven’t had a single hiccup since we switched. I don’t know how we didn’t try it sooner. Great job google!!!
Emma Nyce on 2/3/2018
Duo is great but i wish if someone called u instead of getting a notification you phone rang loud i always have to normally call my friend and tell her to go on duo and then i call her because I doesn't ring unless ur on the app duo but when your not u just get a notification so i think u should make it so that it rings loud when ur not on the app but...
Pamieann on 2/3/2018
Great to talk to family with no dropping of calls and great clarity! Love it! Better than FaceTime!
So easy to call people!

This app is so cool it lets you call the non iPhone people
App drains my iPhone X
jleon0913 on 1/30/2018
Used this previously on my Samsung Galaxy S8 with no issues. Recently downloaded it onto my iPhone X and it burns through my battery. My phone overheats and battery drops over 30% in 10-15 minutes. Really unfortunate. And now the knock knock feature doesn’t work after the latest update. I used to at least be able to open the notification and click preview to see the knock knock feature when a call came through. Now when someone calls me on Duo it looks like a phone call coming through despite us both having the knock knock feature turned on. Kinda disappointing.
