I like the idea of "chat is your to-do list, and your to-list is your chat", but you're website doesn't communicate this, I had to try it out to really get what the product was about.
It's annoying that I can't delete the first loops from Loopy.
I also think the app needs an easier way to navigate between loops, rather than relying on the back button.
I think the user list is not very privacy focussed, I remove it for a username search instead, rather than just listing everyone.
It looks really polished though and I think you have proved the fact that you can create a web app by yourself.
Have you made a pitch deck yet? I've done a bit of fundraising in the UK.
Good luck from a fellow northener!
