Stream, cast, record and download Netflix, Hulu, Amazon and many more channels. Existing subscriptions to services such as Netflix are required, although there are some free channels. Geoblocking needs to bypassed to access most of the content.
Honestly not much. This is just a web based screen recorder for online services.
You can pirate everything you need in much better quality.
If you wanted to be a little more legit you can screen record netflix and all the other services yourself.
As far as I can see you are paying $20 so you can record 720p Netflix, which you can do yourself.
It is one solution to be able to access Netflix and others in Kodi. I tried it but wasn't great.
It's very problematic. I have had it a few months. One day it works perfectly (despite max resolution of 720p), and the next day it's pure crap. I can no longer access my Amazon Prime Video (US) account and as I now have 2-stage verification on all my Amazon accounts, PlayOn.Tv cannot appear to be able to handle this. I have advised their (PlayOn) support of this a week ago and to date no response. I cannot cast to my Chromecast devices but it continue to try and miracast to my now defunct WD TV device. The settings are limited and I can't fix this. On some days I can access my media from my Android smartphone and tablet and the next day I can't. Whenever something fails, I receive an error code but no translation on what the code means. Their web-site provides no clues either. Finally, the software does not advise or update automatically. You need to visit the web-site periodically for updates and download and install manually (so last decade!). Fortunately I only paid USD19.99 for this piece of crap and so my financial outlay is limited to this as it is not worth any more than that. The only benefit I have had so far has been an ability to record for free old back catalogue movie titles which don't come up on Netflix or Amazon, else it is not worth a bother.
In short, their software needs a serious audit and update, and while they are at it they should refine their support.
What is use case? Support for a lot of streaming services has stopped over time and every other day support for existing service breaks down. Highest resolution it can record in is 720p. Too many issues and I don't see any value in it.
