It is good

Iphone overheats
Pccoach33 on 5/24/2018
When video chatting on Duo for 10 minutes, my iPhone 8 overheated to the point of shutting down with a big red thermometer on the screen. I could barely touch it to turn it completely off. The ring tone is hard to hear when a call comes in. Otherwise, we like the video quality.
My review

I call my friends and sometimes they say the screen turn a weird color. Pink, purple, or green. But thus app I would still recommend.😃😃😃😃
Drains battery
lkjafowherpgiawrg on 5/24/2018
I really like the app except for: 1) drains my battery very quickly and by a huge percentage!! It’s pretty ridiculous & is hard to share my son with his grandparents with the app. 2) the small bubble of yourself doesn’t show the entirety of what the other party sees
rezplusmim on 5/24/2018
Great app. Great quality. I always used Androids with androids and iPhones with iPhones for video calling but now because of duo I can keep my iPhone and call my rest of my friends and family who use androids.
Great App

I only use it for FaceTiming people that don’t have apple phones but it works well
My review
kirallsten🔪🔪 on 5/23/2018
This is a great app and it’s goof for phones that can’t face time. Some times it’s a little glitchy but all phones do that, so it is fine. I gave your rating a 5 star because it is the only one I could find that is free and works good! So keep up the work! From, Kirsten allen

Poor bandwidth is no issue
raymwolfe on 5/22/2018
This thing is just simply phenomenal, it preforms with clear video and good sound even in the poorest of connections. What is this sorcery?

Duo coolio
ForTheCar101 on 5/22/2018
Great! Just one suggestion
nateh2222 on 5/22/2018
I love app! Its great! Just one suggestion: lets move the tiny circle to the top left (or right, although i would refer left) because no one’s self-facing camera is at the bottom. Or maybe we could have it so that you could move it around?

Something that I finally like from Google
aJessikababy on 5/21/2018
I really like this app this app allows me to talk to my very favourite favourite person who can’t call to Canada but with this wonderful app we get to interact with one another it would be nice if this app had the capability of being able to send messages inside this app but keep up the good work

Needs improvement
Zjr_82 on 5/21/2018
Duo is a pretty good alternative to Apple’s face time. However the quality of the calls are inconsistent. I’ve also had issues at times of knowing exactly how much of me & my background the person I’m speaking to can see. The other issue I ran into is the circle in which I can see myself is very small. I believe Duo should modify that.
Drains battery and causes phone to overheat.
WzrdRae on 5/20/2018
although the video and sound quality is acceptable, this app drains my phone battery and causes it to overheat even with no other apps open. i don’t like that when i’m receiving an incoming call that it pops up as a notification instead of an actual call. also, it took over the facetime setting on my phone. if i choose the facetime option on a contact, it immediately transfers it to a duo call. please fix this, especially the overheating part. it’s really annoying and my phone never overheats.

Batfart on 5/17/2018
I really love this app because I can call my friends that don’t have an IPhone like me but it is kinda annoying when it buffers and when someone’s phone dies you don’t even know it just says pause and you just sit there and yell their name
so goooood
Matt Matt LOL on 5/17/2018

YaGirlKP on 5/16/2018
This is the worst app ever! Tried calling my mom and friends and it keeps messing up! This doesn’t work at all! And it only lets the call go through for 1 sec and then hangs up. Don’t recommend anyone getting this!
رائع جداً

i love this app and it’s so easy to call people. plus it keeps your numbers organize by there first name and it’s just so great. I LOVE THIS APP!!!!!! If I had to pick facetime or duo I would choose duo because you can call people with samsung or Iphone or an LG . So that’s why I love duo!❤️

mmaederm on 5/14/2018
Duo is a great way to contact friends or family although it is a bit glitchy it will usually ask you if the quality was good or bad most of the time I say good it is an awesome app I highly recommend it
Video message
HTWells on 5/14/2018
The quality of the video is good. The issue is that we are not able to send a message without calling.
