Hi and Welcome!
Be sure to read over these Do’s and Don’ts -
Read and subscribe to Adalo’s performance updates (it’s been quiet for a while, but when there’s an update, it’ll show here).
Also just need to realize that no-code tech like this is meant for precisely what you mentioned you love about it so far being; great to use and has an easy learning curve. Adalo is meant for as many people as possible to build as many types of apps as possible. Performance simply won’t be as fast as a fully-coded app designed for one purpose of one customer. That being said, they’re working on it as fast as possible on all fronts of performance. When I first joined over 18 months ago, a simple back button would literally take over a minute to work. I imagine 2022 is going to be chalked full of performance improvements.
