DownTube allows you to download videos and store them in the gallery as an mp4 or to native music app for FREE.
Just copy the link of the video you want and paste it in the application. Hit search to find the video, choose whether you want it as a video or as audio and you are ready to go.
No more video managers filled with ads, download everything you need directly to your device and enjoy it without needing an internet connection.
No paid features at all, the app is completely free, you will have just an ad banner at the bottom of the screen and a full page ad when you download a video (you need something to do while the download is in progress).
Suggestions and feedback are highly appreciated.
