Phone Call Alarm Clock: How ReminderIt Works as Your Most Reliable Wake-Up
ReminderIt works as a phone call alarm clock — placing an outbound call at your chosen time so your phone rings like an incoming call, not a dismissible notification.

A phone call alarm clock isn't a physical device — it's a service that calls your phone at the time you set, making your phone ring like any incoming call. This approach turns your existing phone into a more reliable alarm: instead of an alarm app running on your device (subject to battery, DND, and habituation), the 'alarm' is an external call that arrives through the phone network, independent of your device's state.
How a phone call alarm clock differs from a regular alarm
A regular alarm clock (or alarm app) generates a sound from a device you control. The sound is local, the system is on your device, and any failure of your device or its settings means the alarm fails too. A phone call alarm clock — like ReminderIt — is a service that dials your number. The 'alarm' is an incoming call from an external system. Your phone rings the same way it rings for any call.
This matters because your phone rings for incoming calls even in contexts where alarm apps can fail: certain DND configurations allow calls through while blocking notifications, the social-response waking reflex is stronger for calls than alarm tones, and the call requires active engagement (answering) rather than passive dismissal (swiping).
Setting up ReminderIt as your alarm clock
Message ReminderIt on WhatsApp at https://wa.me/14786061901 and say it in plain words: "Call me every weekday at 6:30am — good morning, time to get up." No app to install and no sign-up form. Once set, it fires every morning at the specified time without any further action from you.
Unlike a physical alarm clock, you can change the time from anywhere — send a message like "move my wake-up call to 7am", or log in at reminderit.com from your laptop. Pause it for holidays. Add a one-off call for a different time on a specific day. All managed in a chat, without touching any alarm hardware.
The snooze function
When the call arrives, a WhatsApp message comes with it, carrying Done and Snooze buttons. Tapping Snooze is the equivalent of hitting the snooze button, but with an important difference: you have to pick up your phone, open the message and choose, which means you've already engaged with the alarm rather than swiping it away in your sleep.
For heavy sleepers, there's a built-in second chance: if you don't answer, ReminderIt calls once more about 5 minutes later. If you know you tend to snooze, set the call 15–20 minutes before you actually need to be up, and let that buffer work for you rather than against you.
