How large can my photo library be?

The free version supports 1000 media items; purchase a license to have this limit removed.

It has been tested on photo libraries with 300k media items (which takes up a few hundred gigabytes on Google Photos' storage) and works without a hiccup. While there is no specified upper limit to the number of media items a licensed copy of gScreen can work with, your mileage may vary if your library is significantly larger than this.

Please let us know if this describes you: we'd love to help you test the app against larger libraries.
