Just started to use this app and it seams very similar to other building apps and works well. My only issue is that I need to use a desktop site to preview the app.

Good app, but still, it needs upgrades and improvements. It can produce basic app prototypes but lacks with advanced and complex apps, it's user-interface is also bad, not smooth, and ai also shows so many bugs and limits.
