For most folks, the built-in BlackBerry 10 video player works fine but for those who are looking to get a bit more features added into the video player there's Nutty Player. Although the app has been around for a while now, I only recently decided to give it a look in and I have to say I'm quite pleased with it considering it's available as a free download. While maintaining a lot of the features from the stock video player, Nutty Player takes your video watching experience on BlackBerry 10 to another level.
My favorite is the touch gestures they've included. While they do take some time to get used to using them, they make skipping through videos quite easy and the volume adjustment without having to touch any buttons is just plain awesome. Other features include the ability to add videos to a favorites list and a cool watched video video indicator that allows you to easily identify what you've watched already. It's not often I watch stored videos on my device but Nutty Player certainly helps when I do.
