The apple reminder app(s) work surprisingly well for many cases:

* macbook: at a desk or whenever/wherever it is accessible

* iphone: quick note pretty much anywhere like train ride

* apple watch: running, in the pool, during sauna session or in the gym weightlifting

* siri: while driving car or riding bike

These all end into a single inbox.

Unfortunately this requires full buy-in into the apple eco-system.
