30 days into building a medication reminder app for my mom in her 70s.
I started with what looked like the obvious problem: she keeps forgetting her morning pills. Set a reminder, take the pill, mark it done. Easy.
It's not.

The real problem isn't reminders. It's uncertainty.
Habits like working out or journaling reward you with a sense of progress. You feel proud of a streak. You might even share it.
Medication is the opposite. Nobody is excited to say "I took my blood pressure pill today." It's something people have to do, but don't want to think about.
So the core motivation isn't achievement. It's *reducing uncertainty*.
---
The moment I understood this: my mom called me one morning.
"I can't remember if I already took my pill. Should I take it again, or skip it?"
She wasn't worried about missing the pill. She was worried about taking it twice.
That phone call killed half of my v1 design.

Once I started looking through that lens, the problem broke into time scales:
- **When the alarm rings:** "Which pill? How many?"
- **Later in the day:** "Did I take the morning dose? Or am I about to take it twice?"
- **This week:** "Have I been mostly on track?"
- **At the doctor's office:** "Have I been taking this regularly?"
What surprised me: the most important screen isn't the long-term report. It's *today*. People don't open a medication app for a dashboard. They open it to find out whether today is okay.

The family side of the product changed too. Adult children don't want more data about their parents — they want to know, from far away, whether mom or dad is okay today. One screen. One answer.
---
The reminder itself is still critical. If the alarm fails once, the user is right back in "I don't know if I took it." That's why I've spent more time on alarm reliability than on every other feature combined. Boring work, but it's the foundation.

My current product principle:
> I'm not trying to make people care more about medication. I'm trying to make medication require less mental effort.

For other indie builders working on health, caregiver, or productivity tools — when did you realize your users wanted certainty rather than data? What did you cut from the product because of that?
