InstaSniper

InstaSniper is a useful app that lets you download any video hosted on Instagram in a quick and easy way. All you need to do is activate the app and start to browse Instagram as you would normally. The special thing about this app is that you don't have to access anything directly from it; instead, you can activate the app and then close it, letting it keep running even if you don't remember that it's there.

Once you download the app, the first thing you have to do is tap on the big red button to activate it. Once the button turns green, showing you that it's activated, you can close the app and forget about it as it works in the background. Then open the official Instagram app and use it as you normally would. Whenever you find a video that you like from one of the people you follow, all you have to do is tap on the three dots below the video and select the option 'copy URL.' After that, the download will begin.

Everything you save will be stored in the same folder with the name of the app, InstaSniper, without leaving a trace or notifying the user that their video has been downloaded by another person. Since there aren't any limitations, you can access videos as fast as Instagram will load them, and the download itself shouldn't take more than two seconds to finish.

When you're done using the app because you're not going to use Instagram for a while and you don't want to waste resources, all you have to do is slide the top panel down and tap the small green button that indicates that the app is still activated. When it opens, just tap the center button again to turn it red. And then, when you want to download something again, all you have to do is activate it again. It's that simple!
