Hydration reminder calls set by Claude

Drinking enough water is one of those intentions that evaporates the moment work gets busy. A short call that says 'time for a glass of water' cuts through in a way a silent app badge never does. With ReminderIt connected to Claude, you can space a few of these through the day and adjust them by talking, while keeping a sensible eye on how many calls you are using.

Interval or fixed times

There are two natural ways to spread hydration prompts. An interval keeps a steady gap, which suits a workday where you lose track of time. Fixed times pin the calls to moments you will remember them by, such as mid-morning, after lunch and mid-afternoon.

Claude maps both onto ReminderIt. A steady gap uses interval_days for day-level spacing, while several times a day are simply several reminders, each with its own time. It confirms your IANA time zone so the calls follow your actual clock.

Setting three spaced calls

A clean, quota-friendly pattern is three calls on weekdays. Say: "Set three daily reminder calls on weekdays, Europe/London, at 10am, 1pm and 4pm, each saying 'Time for a glass of water.'" Claude runs create_reminder three times, with crons of 0 10 * * 1-5, 0 13 * * 1-5 and 0 16 * * 1-5.

Ask "What's scheduled today?" and it runs list_upcoming so you can see all three lined up. If one time clashes with a standing meeting, update_reminder nudges just that call.

Keeping it within quota

This is the part worth thinking about before you get carried away. Every call counts against a pooled monthly allowance: Free gives you 5 calls a month, Pro gives you 70. Hydration is tempting to over-schedule, so do the sum first.

Three calls a day, five days a week, is roughly 60 calls a month, which fits comfortably inside Pro but would exhaust a Free plan in a single day. On Free, one well-placed daily prompt is the realistic choice; on Pro you have room for a proper spread.

Checking your usage as you go

You do not have to guess where you stand. Ask "How many calls have I used this month?" and Claude runs get_usage to report your remaining allowance. If you are burning through it faster than expected, thin out the schedule by asking it to delete or pause a couple of the calls.

Because inbound WhatsApp chat to manage reminders is free and unmetered, you can also tidy the schedule that way without spending a single call.

A cue, not a nag

The aim is a gentle rhythm, not a phone that rings all day. Each call is one-way: it says its line and rings off, so it never interrupts you for longer than a few seconds. If you miss one, ReminderIt can send it as a WhatsApp message instead.
