Just the reminders app. Also, I use water llama app for hydration. One symptom of my adhd is I get neither hungry nor thirsty like normal people so hydration is key.

yes i have a 1.5 liter bottle and i have to empty it till end of work. its allways on my desk. its so hard to do stuff i am not directly interacting with atm.

I’m not the one you asked, but I rely heavily on the Apple’s Reminders app.
