Set a recurring measurement reminder

You measure weekly, but only when you remember — which means three out of four weeks. You want the agent to nudge you on a fixed day so the cadence stays clean and the trend chart doesn't have gaps. You tell it the schedule once, it nags you the rest.

What the agent needs to hear

Behind your sentence, the agent works backwards to three pieces: what to measure (weight, specific perimeters, or both), the cadence (« weekly », « every two weeks », « monthly »), and the day and time (« Sunday morning », « Monday 7 am »).

« Remind me to measure waist every Sunday » carries all three — site, weekly cycle, anchor day. The agent shows the schedule on a preview card before saving, so you can see exactly which days will fire over the next month.

If the sentence is ambiguous (« remind me to measure » with no day), the agent asks for the missing anchor rather than guessing. Naming the time explicitly is what locks the nudge to a repeatable moment.

Cadence, time, and what gets nudged

Cadence has four shapes. Weekly is the most common — a fixed day each week. Biweekly locks to the same weekday every two weeks. Monthly fires once per month, anchored on a date or « first Sunday ». A custom interval (« every 10 days ») counts days and fires on the cycle.

Time defaults to morning fasted — the standard measurement condition, before breakfast and water. Override with a specific time when your routine asks for it (« 7 am », « after my Sunday run »). The agent uses the time to schedule the notification, not to enforce a window.

The nudge itself is a notification — it doesn’t auto-log anything. When you respond, you go through the regular log path (single-sentence weight or perimeter log). Multiple reminders run independently: a weekly weight reminder plus a biweekly perimeter reminder, no conflict.

Why scheduling beats remembering

The trend chart and longitudinal narrative read better when the log cadence is consistent. A weight series with logs every Sunday for 12 weeks is a clean line; the same series with three sporadic gaps reads as noise.

The reminder closes the gap between « I should weigh weekly » and actually doing it. The schedule does the remembering so the measurement happens on cadence, not on whim.

It also keeps measurement conditions consistent. A Sunday-morning reminder means you measure under the same conditions each time — which is what the trend reader needs to draw the curve honestly.

When the agent gets it wrong

The preview card carries the next two or three scheduled dates — read those before nodding. Three failure modes worth catching: the cadence parsed wrong (« every 14 days, not every 14 weeks » — the schedule will show the difference), the wrong measurement target (« weight only, not perimeters too »), or the time-of-day misread (« 7 am Sunday, not 7 pm »).

Each one is a single sentence to fix — name the difference and the agent re-renders the schedule.

What makes the reminder worth setting

Three things decide whether this reminder helps your trend chart: the cadence matches what you can actually sustain (weekly is the sweet spot for most; daily is over-measurement; monthly is too thin for short cuts), the time anchors a repeatable measurement condition (same time, same state — fasted morning is the standard for a reason), and the reminder is acted on, not dismissed (a reminder you ignore three weeks running is signal that the cadence is wrong, not that you need a louder nudge — adjust the schedule). A sustained cadence is the difference between a curve and a scatter plot.
