Why I Built This

Medication Diary started from one difficulty I kept running into in the exam room — putting a day's changes into words turns out to be far harder than it sounds.

What is hard to put into words

"How have you been lately?" is not an easy question to answer precisely. What stays in memory is usually the hardest moment and the best moment, and everything in between blurs. The interval between the time a dose was taken and the time the body changed is exactly the kind of information that memory holds onto worst — and it's exactly the information that matters most.

A record changes the story. Even describing the same day, "the afternoon is hard" and "the curve doesn't rise as high after the third dose anymore" carry completely different amounts of information.

Principles behind the record

There are a few things I tried to hold onto while building Medication Diary.

  • Don't force a judgment. Instead of making you choose between "on" and "off," it asks only how things are right now, by degree.
  • Don't make the interpretation for you. The app doesn't decide what to do based on your records. Decisions about medication type, dose, and timing belong with your treating clinician.
  • Records stay yours. Records stay on your device, and you can export them at any time.
  • Don't invent what isn't there. The app never shows a curve or a prediction that isn't backed by an actual record.

What this website does

The app alone wasn't enough. The same two comments kept coming back — looking at a graph and not knowing what to look at, and hearing a word in the clinic and not knowing what it meant.

This site exists to fill that gap. It defines the terms used to describe medication fluctuation, explains what to look for in a curve with illustrations, and covers how to bring your records into a clinic visit.
