Repository files navigation


Application can remotly control Panasonic Lumix Cameras from Windows 10 devices (PC, Mobile, ... Xbox, Hololens!?)

Former name GMaster.

Application can do no more than original app from Panasonic for Android/iOS. While for now app does not support all remote features, supported features work in a better and faster way. And if something is wrong or not enough I can fix it much much faster than Panasonic in their app.

App is free and has no ad. You can install it from MS Store or from Project Release page
