[Closed] small project planning software

Anybody got a recommendation for some project planning software/application. I am not a project manager, trained or otherwise. Probably something similar to microsoft planner (which I should have access to in a few months but the office 365 rollout is on hold currently) and I can't get that with my home 365 subscrition.

I just want something simple and visual to help (mainly myself) organise small projects, something I can put a few milestones and due dates on, split into sub tasks ect, without getting too overblown and getting into proper project planning methodology.
