Another possibility may be to use the second SD card in the K-3 or K-1 bodies, to store the app, rather than rely on a mobile link.
I added something to my post to clarify. A magic lantern solution would be perfect. I don't like a solution where you need an additional device to handle with your camera.
concerning post #8 The camera must be commanded to do the single pictures to get stacked - move focus get picture... -. Therefore I need commands for the api to do that. This must be implemented in firmware and I don't like to send hundreds of commands over a ''instable'' wifi, to do a task.
A magic lantern solution will have a type of macro to define start, end, number of steps, change per step and a possibility to trigger the series. This works standalone even in a harsh electronic environment. I can simply start it by a remote trigger. I've no problem to transmit the parameters by an app and start it by an app as an additional option - but the work should be done in camera only. The stacking can be done much, better on a computer. I don't want to transfer 40 to 50 raw pictures (2 GB Data) over a slow wlan connection to mobile and waiting hours for a result. I want the full capacity of raw development that is available on a fast computer. Stacking is in my opinion post processing, same as panorma-pictures (Hugin, PS CC).
In a lot of enviroments you've problems to have a stable wifi connection - I don't want loose a set of pictures because of wifi.
