I don't have any time delay between pills, tho understand that some pills do have to be taken seperately.
What I've done is to set the pill bottles in the area where I eat my meals, since that's when I take my meds. I sit down to eat, I take my pills, everything's good, and I keep my doctor happy. 🙂
Occasionally I might forget, but that usually happens when I'm trying to do 3 other things while I'm eating.......and I usually remember a little while later.
Also, there's pill boxes with AM and PM if you need it, days of the week pill boxes, etc.
If a watch with an alarm feature doesn't work for you, there's also clock radios with dual alarm functions.
