I have tried using a calendar event with reminders and Google Tasks but they are not really the right tool for this. I have two medications that I take that are not on a consistent day. I take Aimovig for migraines, and I take it every 4 weeks (so this one the day is consistent but not the date). That way I get 13 doses in a year instead of 12. I also started testosterone recently and I take it every 10 days. This one is terrible for me to remember. Plus, it comes in 3 vials (injection), so when I take the last one I have 10 days to get a refill. But due to it being a controlled substance, I can't request a refill until 25 days (I think it is. I just know I can't do it immediately after doing the last injection). I also can't do the normal medicine refill request in MyChart because it's technically not a refill. They send 3 prescriptions with future dates to the pharmacy and each one is a new prescription and not a refill. I have to message the doctor in MyChart. They respond very quickly, but I sometimes forget until like the day of.

The calendar and Google Tasks don't work because let's say I forget and take it a day late. Both of those tools will remind me to take it again 9 days later instead of adjusting to 10.

I need an app that can let me setup my medicine schedule and get reminders that will adjust the next reminder if needed. I also want it to remind me to refill a prescription based off the last time I filled it. Does anyone have any good suggestions?
