Editors' Review for Anime Tube Unlimited
Anime Tube Unlimited has several thousand anime TV series with the best quality. It has multiple sources which allows it to boast a library of almost 10,000 titles which can be sorted by an extensive filtering system to looking for what you want from the things that would be otherwise irrelevant.
You don't have to worry about forgetting where you left off since the app remembers it for you even through uninstalls, because it stores everything on the cloud.
As for the video quality, this anime streaming tool will always deliver by default the best quality image available, varying anywhere from 480p to 1080p. If bandwidth is an issue, you can just manually select a lower quality setting, and Anime Tube Unlimited will remember it too.
