How are you actually keeping track of your parent's meds and supplements without losing your mind?

Looking for real systems, not platitudes.

My mom takes 6 supplements plus 3 prescriptions and I've been the one running point on it for the past year. Pill organizer helps but only if I remember to look at it. Notes app is chaos. I tried two of the commercial med trackers and they both assume one user managing one set of meds, neither handled "track for myself AND for her, separately, with shared visibility."

So: what does your actual setup look like? Whiteboard on the fridge? Calendar reminders? Some app I haven't found? Something low-tech I'm overcomplicating?

Really trying to figure out what works long-term, not what looks good for a week.
