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 your monthly allowance: every plan includes 70 reminder calls a month, and the 7-day free trial includes 10. 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 inside the 70 but leaves little room for your other reminders. A good option is to make hydration prompts WhatsApp-only, since WhatsApp reminders are unlimited, and save calls for the reminders that really need your phone to ring. You can choose calls, WhatsApp or both for each reminder.

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.

You can also tidy the schedule by chatting with ReminderIt on WhatsApp ("list", "pause 2", "cancel 3") 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. A WhatsApp message with Done and Snooze arrives alongside it, and if you miss the call, ReminderIt tries once more about 5 minutes later.
