With last night's ArcGIS Online update, ArcGIS Experience Builder introduces Express mode, designed to make app building easy, enabling you to quickly and efficiently make engaging apps. Choose from a variety of templates to begin creating a new app, then follow the streamlined workflow to complete your experience.
Use the mode toggle in the upper right to go from Express mode to Full mode and vice versa.
The app templates are similar to the Web AppBuilder classic templates.
