Glide Apps work on all browsers, iOS, Android, tablets, and desktops.
All Glide Apps work on mobile devices. If your app is Pro then you can enable Tablet/Desktop mode in Settings/Appearance.
The checkbox for tablet mode when your app is Pro
If your app is a free app, users on Tablet & Desktop will see a Mobile Preview which they can interact with.
If you've enabled Tablet/Desktop layout, you don't need to do anything to re-configure your app. Glide Apps automatically change their layout, depending on the device that's viewing it. Apps will change from mobile to tablet/desktop when their portrait width is larger than 600px.
As well as the layout being simply bigger, Tablet/Desktop has some important additions.
In tablet/desktop, lists have a Master-Details layout. In other words, your list stays persistent on the left, and when you click on one of the list items – the details layout on the right changes.
