From where do I download apps and use as shown in YouTube videos

I can find lot of videos in youtube store, where can i find these pre built apps in Tablesprint. Any help here?

Youtube vieos are available under app store of our main dashboard when you click create…check the screenshot below…

you can also preview the app before creating it…check the screenshot below

once you create it will also show you the data sheets to be filled by your own data…previews may not show all sheets/views and apps…
