Adalo could be the easiest no-code app builder out there (as of 11-07-2022) which is the main reason why many people to start to use it.
There are some fundamental issues which makes me to suggest to check other builders. (I'm a paid user)
- Quite bad customer service
-There is the community but their forum is little neglected by the Adalo's team.
-Apps you will build will end up being very slow
I suggest you can invest time to learn another a little more complicated product (Draftbit, Appgyver for instance) since you will most likely end up rebuilding your app you developed with Adalo.
