Use ReminderIt with Claude on your phone

The best time to set a reminder is the moment you think of it, and that moment is usually when you are away from your desk. If you use Claude on your phone, ReminderIt fits neatly into that habit: a quick message on the move becomes a scheduled phone call.

The connector is tied to your account, not a single device, so once you have connected ReminderIt it works from Claude on your phone just as it does everywhere else.

One account, every device

ReminderIt connects to your account, so the reminders you set from your phone are the same ones you see on your laptop. Set a call from Claude mobile in the morning and review it from Claude on the web that afternoon — it is one shared schedule.

If you have already added the hosted connector on another device, you may just need to be signed in to Claude on your phone to use it there too.

Connecting on mobile

The setup mirrors the desktop flow. In Claude's connector settings, add a custom connector with the URL https://mcp.reminderit.com and sign in through the OAuth screen. No API key to copy, which is a real advantage on a phone where typing secrets is awkward.

Menu names vary between app versions, so look for "connectors" rather than a fixed path.

On-the-go examples

The value shows up in everyday moments. Leaving the pharmacy: "Remind me to take the new tablets at 8 tonight." Walking out of an appointment: "Set a call for six weeks today at 10am to book my follow-up." Standing on the platform: "Cancel tomorrow's 6:30 wake-up, I'm off work."

Each of these maps to a real tool — create_reminder for the first two, delete_reminder for the last — and Claude confirms the time zone so the call lands at the right local time. When it does, a WhatsApp message arrives too, with Done and Snooze.

Check in from anywhere

Because your usage lives on the account, you can keep tabs on it from your phone. Ask "how many calls have I used this month?" and Claude reads it back through get_usage — handy when you're pacing the 70 reminder calls every plan includes each month (WhatsApp reminders are unlimited).

You can also ask "what's coming up?" to glance at your schedule with list_upcoming before the day gets away from you. Not connected yet? The same sentences work sent straight to ReminderIt on WhatsApp at https://wa.me/14786061901.
