Disclaimer: I write down my business ideas that I can implement in a day or in the worst case less than a week. The principle is to figure out something simple but still useful. I may do or not do them in the future but I write them down to offload them from my head to make space for other ideas.

Idea: minimal todo app with re-occurring events.

Hire: someone who does not need all the fancy functionality.

Price: 1$/1€

Direct Competitors: https://todoist.com (but their free version works poorly nowadays), https://www.any.do/

Indirect Competitors: not aplicable

Why I think I can do it fast: it is really simple app

Blockers: no
