About this app

With the useful functions of Gema‘s Electrostatic App you control and monitor your Gema OptiStar 4.0 equipment in real time:

Application: All essential OptiStar 4.0 coating parameters are clearly visible on a Smart Device and can be directly adjusted and controlled. Designed for use with manual or automated Gema equipment.

System information and diagnostic data are easily retrievable and can be sent via e-mail. The automated firmware update keeps your OptiStar 4.0 up to date.


Service: Direct access to the user manuals of the system components as well as the Gema website.

Ratings and reviews

Does what it needs to do, but lacks some features. It would be awesome if one could record a day's worth of powder consumption across multiple jobs and export a big list at the end of the day. As it stands, powder operators need to interrupt their flow and export each job individually as they're completed.

The app must be needed to improve performance, every time I try to open app but it can't open, and show error.

app has bug and keeps crashing
