If you are a power user that relies on the app, you should purchase the pro license. The pro license provides all of the features all the time.
A pro license provides the following benefits:
- Slideshows update with new photos and videos much more often. Note: Auto update is not available with Google Photos.
- Display EXIF/IPTC/XMP photo data in slideshows, such as title, location, and date taken. Note: Photo data is not available from Google Photos.
- Start app when the device starts on devices that allow this.
- Sleep the slideshow during specified hours.
- Rotate the slideshow for vertical TV screens.
- Unlock all app features forever.
- Be the first to receive new features.
Note that on Apple devices, some of the above features are not available.
