A01e is an application that allows you to connect up to eight Wifi-compatible cameras at the same time with the built-in camera, RICOH / PENTAX camera, Panasonic camera, Sony camera, Olympus camera, and Kodak PIX PRO camera. (Images from the built-in camera and Wifi compatible camera can be displayed at the same time and taken at the same time.)
You can also display the operation panel for changing the settings.
It also has a function to display pre-saved images as "examples" and support shooting from the same angle.

You can also store the images a little and display them with a slight delay.

A remote shutter (wired / wireless) can also be used for shooting.
