The design is up to you, if you have the design abilities to make something look great, then it will look like that.
Wappler is not giving you something new as a design tool, but rather giving you easy GUI access to all of Bootstrap 4, Framework 7, and Font Awesome, which are the standard building blocks of most of the web.
I think I speak for a few people on here when I say that Wappler had an initial user base that was more the tech savvy crowd rather than the artistic / designer crowd, therefore many of the designs you see are from people like myself who are possibly better at the technical aspects of website creation and not exactly your top designers.
Wappler has an end goal of trying to bridge that gap, making the technical side of the development easier for people that are designers to achieve.
Wappler has many built in animation options directly accessible in the application, however we are talking more state animations, like on load, on scroll, etc.
If you wanted something in the realms of snapchat, which can make your face into a dog or a cat, and that is what you mean by animation, them I personally am not even nearly technically proficient enough to create something like that in Wappler or any other tool on the market for that matter. Snapchat would take a team of highly talented people to put something with that sort of facial recognition technology together. More like the technical minds of the people who made Wappler, not like the Wappler users.
You could create something like Instagram, or Facebook, from a functionality perspective, and design it to look however you like.
