Since it's so popular, many users have tried to find a way of downloading it on other operating systems although there's no such thing as an official version, as is the case of iPhone and Windows.
One of the most popular options on Android is Vidmate, which intends to rival with others of the likes of Tubemate, and it manages to do so thanks to its great functions: compatibility with different services, possibility to extract the audio and even a built-in app store to discover new tools for our mobile device.
Although there are millions of online videos available on YouTube, Vimeo, Dailymotion, and other streaming platforms that we can access whenever we want (provided that we've got an Internet connection), there are also loads of other programs to download them.
