While not having the colours of ToDoist, I would suggest you give OmniFocus 4 a go (but be warned, it does have both a learning curve and a set up time cost as you add initial projects and tags).

I like my productivity porn, I’ve tried most (Mac, Web and iPhone) personal task list tools over the years, but OmniFocus is the one I come back to.

Capture is easy (quick capture menu bar, email, Apple reminders, voice via Watch).

Review is easy (there is even a per project periodic review you can set).

Calendar (called Forecast)

Projects, tasks and subtasks

Customisable personal screens (Perspectives)

Locations (add a location tag and your watch will flag items to do there e.g. renew season ticket at the station, buy particular items at the shops, talk to your sister about UPF).
