The tracking habit that survives past month two is almost always the one that doesn't require its own decision about timing. When the log entry is a separate task — something you intend to do weekly, without a trigger — the question 'when should I log this?' has to be resolved every week, and on the weeks when the answer isn't obvious, the log gets skipped. Dose day eliminates the question.
The dose already happens on a fixed day. The log fires on the same day, attached to the same moment — the anchor is already in place, and the new habit inherits the anchor's reliability. The specific timing within dose day matters less than the consistency of the anchor: logging immediately before you dose means the previous week's experience is fresh and the dose hasn't yet shifted your reference point for how things feel; logging within an hour of the dose is the practical fallback for most weeks.
What matters is that the decision of when to log is made once — 'I log on dose day' — and then never made again. The habit doesn't require motivation on week eight because it doesn't feel like a separate commitment; it's a two-minute extension of a ritual that already happens every week. The practical mechanics are simple: set a weekly reminder on your dose day, fifteen minutes before your usual dose time, with a single prompt — 'log before you dose.' The reminder isn't necessary once the habit is established, but it carries the habit through the first six weeks while the anchor is still forming.

Titra's recurring reminder is set up in two taps — pick the day, pick the time, choose 'log before dose' as the prompt text, and the app handles the rest. The goal is to make dose day and log day the same day until the association is automatic.
