It crashed after watching for 20 min, it will continue to play sound while the app freezes. It will crash if you switch to another app. Now my app is crashed forever no matter how I try to reinstall it… course is expensive but I don’t understand why you don’t invest in building a better app :( ### 1/5 — Always crashes *2024-08-03* I have never successfully went past the login before. It just crashes. 0 start if I can ### 4/5 — It works *2024-05-12* The app works fine. No issues, class videos play smoothly. I’d prefer the app than the sketchy Koloso player they require you to install on PC. For iPad and mobile it seems to be alright. The content is good though since you’re learning from professional illustrators. Only 4 stars because on PC it’s very sketchy, I’m not downloading that on my PC. ### 3/5 — Great content, buggy app :( *2024-03-08* I have no problem with subtitles, already figured that out, but having the app (and browser) crashing all the time has gotten annoying. Right now I can’t even access the app which is a huge bummer. All Coloso needs is to run stabler! I’ve bought a handful of classes and they really are good! I just want to be able to watch them without it crashing or freezing up. ### 1/5 — Unable to use External Monitor *2024-03-04* External monitor support is something that is basic functionality in iPad and iPhone 15 over USB-C. Plugging in a USBC to HDMI adapter says recording software detected, close the app and try again. This is unacceptable. Every video streaming app allows external monitor support. ### 1/5 — Does work in Dubai and bad customer service *2024-03-02* The video player they use is dumb. It doesn’t work in Dubai and there are not even responding to my mails. I paid 16k INR to not have any of the videos accessible. I need help or I need my money back ### 1/5 — Terrible App *2024-02-07* For the amount of money you spend on a course, there is barely any guidance on what the best platforms are to use the app. You only learn about it when you get pigeonholed into using the app when you realize you can’t watch it on your iPad browser. Then when using the app, there is so much latency I don’t know how anyone manages to use this. My video always stutters and, in the last hour, wasn’t able to connect to the server about 10 times before I gave up. This is all the while I’m able to watch short-form video or listen to audiobooks just fine on the same wi-fi network. Save yourself the energy, just watch it on your computer. ### 1/5 — Disappointing *2024-01-24* So far I have found accessing content by Coloso more difficult than most. I didn’t want to install the separate Kollus player on my new M2 Mac as it would also require me to install Rosetta. The separate video player is required so I thought I’d try this iPhone app. New problem - the audio doesn’t work. Well, it only works if I use headphones. The app is glitchy too and randomly shuts off. This is all too tedious and disappointing. ### 4/5 — Its Alright *2024-01-06* Does the job fine for a video player, just wish i could do more in the app. If sound doesn’t work, try turning on ringer and switch the player mode to built in ios l. ### 1/5 — This app s*ck also some courses are low quality for 160Aud *2023-12-04* Don’t use it ## Frequently asked questions about Coloso ### What can I do with this app?
