And I did forget something: visibility.
Usually when I have something time sensitive, I get really paranoid to forget about it, so I look at my phone notes (which I try to title).
The stm planner is great because I can put it on my desk. Everything I need to ask someone, or if I need to remember to look at an image etc, also lands in my notes (which then go into my archive when done). I also often add the room names (bath/my room, etc). I will also write "look at planner". I also do that with to do lists I have written physically.
If I believe I might forget it, I'll put it on my keyboard.
Structured gives me alarms to notice it, which is nice. Since I struggle with time blindness, I tend to not forget looking at my monthly.
Tweek can also be nice for daily todo lists- I believe it does have alarms-, it has three separate lists for repeated tasks and a nice minimalist layout.
I also used Habitica once, which can also do weekly/byweekly/etc tasks and has reminders.
For things I might need sometimes, I have field notes. I don't put time critical stuff in it, unless my phone battery failed (hasn't happened yet).
Something I'd do if I had something frozen that goes bad in a few months would be putting a list on the freezer.
Putting a list on your door could also work.
Basically put stuff in view and I just (am paranoid about forgetting something and) trained myself to always look at my phone's notes.
