Insular (the degoogled open source version of Island) has a page comparing Island, Shelter and Insular

I don’t know if its updated, but you can pick the ones that fits your needs.
I picked Island because I thought I may have issues with my notifications if I had chosen Insular. (Plus, there was this bug I was talking about and thought that it would fix it. Installing Island wasnt the solution, but I had already spent a lot of time/days setting up my phone multiple times and didnt want to try it again, with the possibility of problematic notifications.)
Ayyy
If I’m alone I tend to walk in circles inside for like 0.5-1 hour or more thinking about stuff (with or without music). It’s soothing😌
I also pace when waiting bus etc.
(Even when I sit I pace some times.🫣 Leg goes up and down.)
