There's a specific gap in most journals that only becomes obvious at the appointment: the data is all there but the trajectory isn't visible without significant interpretation effort. The 'one thing changed' weekly marker is the fix. At the end of each weekly entry — after the dose log, the side-effect notes, the other fields — write one sentence answering the question: what is the single most notable thing that changed since last week?
It can be something that improved, something that got harder, something that shifted, or nothing — 'quiet week, no notable change' is a valid and useful entry. The sentence should be in plain English, in your own voice, capturing the change you'd actually mention to someone if they asked. Not a data summary.
A change detection. Three reasons this is worth adding to an existing routine. One — the appointment question your prescriber is most interested in is whether things are trending in the right direction, and that question is answered by change-over-time, not by any single week's absolute state.
The change-flag lines give you the trajectory answer in one read-through. Two — humans are poor at retrospective change detection across twelve weeks. What feels like a gradual, unremarkable improvement over three months is often a substantial shift that the patient has adjusted to and stopped noticing.

The change-flag lines catch the gradual shifts that the patient's adaptation mechanism has made invisible. Three — the change-flag line is also the input for a question worth asking at the appointment: 'this was the week where X changed, and I don't have context for whether that's expected at this stage.' The change-flag converts a passive observation into an active question. The mechanics: one sentence, end of the weekly entry, written at the same time as the rest of the data while the week's experience is still current.
The question to answer is 'compared to last week, what's different?' — not 'how was this week in absolute terms?' The distinction matters because change-detection is the frame and absolute state is secondary. Titra's weekly entry includes a change-flag field as an optional line at the bottom of each entry for exactly this reason — the field stays optional so it doesn't create friction on weeks when nothing notable changed, and it shows in the timeline view as the editorial layer above the raw data when you're preparing for an appointment.
