Todo mobile App

Is there any mobile todo app that anyone has developed?
I feel the need for a quick todo app on mobile many times just to add a basic description and assign it to someone as a manager or quickly refresh what is pending.
something very basic like google keep or notion.

If not can anyone point to a pwa boilerplate for erpnext? just a basic login, I think I should be able to manage the forms.

I’d be happy to create and share the same with the community.
