The Filmcalculator program is developed with the aid of program/company called Appforge. This is why you need to have the 'Booster" application on the device to run the main program.
A few years ago, this was no issue: the booster was included in the program and would automatically install itself and run nicely in the background.
Unfortunately Appforge is changing its licenses year by year to make more money and put their name on display…..
 

We have decide to stop further development of the package that was supposed to incorporate Script/Sound/Camera programs.
There is not enough demand at the moment for Camera Report so we put it on hold.

The good news is that we lowered the price to $29 which makes it a bargain for almost 2 years of hard work on it.
