DSLR Remote App

Hellow r/Photography, so I just found out and downloaded the DSLR Remote App, and it works surprisingly good with my Nikon D5200 and Samsung S4. It has many modes, like you can shot with intervals, hdr, bulb etc. It also has many camera brands (all the main ones), and yo can use it with many phones. If your camera and phone are compatible, I don't think you should waste any money in a remote. I hope this helps somebody!
