Helicon Remote allows you to control Canon or Nikon DSLR cameras remotely and automates focus (DoF) bracketing, exposure bracketing (HDR), and time-lapse photography. It can even combine all these methods together.
Helicon Remote allows to connect camera not only with a USB cable, but also via wi-fi. Please check the list of supported wi-fi cameras here.
Another very useful feature of Helicon Remote for mobile devices is geotagging - travel around and make the shots, meanwhile info on your current GPS coordinates and shooting direction will be included to the image metadata.
Hardware requirements: only Android devices with USB OTG (host mode) support will work with the app. USB OTG adapter is required for USB operation (not required for wireless operation). Run this app to determine whether your device has OTG support.
Note: Although Finder indicates no version number for this application, the developer refers to it as version 3.9.12.
