Hi Kevin,
This is indeed quite a nice tool!
Pix4Dcapture is a flight planning app running with Android or iOS mobile devices (phone, tablet) at the moment.
It cannot be used with desktop devices or any devices running with Windows at the moment.
However, having a desktop version of Pix4Dcapture is a quite popular request among users. Your concerns have been shared with the developer’s team so that consider it in the future with higher priority.
best,
