Check out this simple app https://www.thescatterbrain.app where you only have one focused list of items you need to knock out now. For anything else, stick it in the icebox so you don't forget about it.
I built this for myself as most other todo and task management apps actually distract me and create a lot of noise.
I release updates and bug fixes on a daily basis.
I hope it can help you all too.
It would be nice to get some indication of what it looks like or specifically what it does before needing to sign up.
I confirm that, as I almost didn't subscribe.
A nice way to do it would be to allow people to use it as a guest and show something like "Don't lose your tasks, subscribe here"
