Trash App Constantly Crashes
     
by RobertLBeukema · April 13, 2020

I wish I would have never bought this camera. Good luck streaming live with it when the app constantly crashes.

Camera is great but app is currently garbage

I have had countless issues with this app. After sending borderline hateful emails to the company I received complicated instructions in broken English and was finally able to struggle through and get a single problem resolved. After a short break of filming I anxiously decided to record again. Now the app will not allow me to download clips yet again. Instead of buying anything from this company I’d recommend getting a GoPro. Easy to use, similar quality, 10000% less effort and frustration. YI stands for “You Idiots” that waste money on the product.

Looks like they fixed it for latest iOS!

About time

App hasn’t been updated in a year
     
by William Castro · May 10, 2021

Is a great camera to record 4K videos and if you’re not into livestream or controlling the camera with your phone, this might be a great option for you, unfortunately the app hasn’t been updated in more than a year, it seems that Xiaomi doesn’t care anymore about the app and the connectivity of the camera.

Useless App

Wifi won’t connect to iPhone app. I tried all available tips in the internet but nothing worked. They should take this app out from the App Store coz the developers don’t care anymore and don’t want to update it! I would avoid buying yi action camera from now on. They really thought ignoring this app issue won’t affect their sales! Well, I already sold mine and went back to GoPro!

Call the exterminator, this app has lots of bugs in it!
     
by Cafeboy77 · October 17, 2020

Although the Yi developers had some great innovative ideas for the action cam app, It has many bugs in it. It also freezes often especially when running 2.7 k or 4 k videos. Also camera to phone WiFi has a tendency to disconnect even within 5 ft of the camera. Several other bugs to list... not to mention you get Chinese character messages popping up sometimes. The user should be able to read only 1 language of choice. developers should’ve spent more time on testing the app and fixing bugs. They obviously did not hire top-notch programmers.

Thanks for fixing the iOS 13 issue 👍

Works great so far, thanks

Awful
     
by Antyluter · April 1, 2026

I haven't encountered such poorly designed apps in a long time. The video download speed is incredibly slow, and right at the end, when there's just a little bit left to download, it throws a time limit error. You end up having to download the whole thing again. This is just one of the problems, and there are hundreds more…
