Online Alarm Clock

A free online alarm clock that runs in the browser, fires through your operating system's notification system, and can also message you on Telegram or email when the time comes.

Most browser alarms break the moment you close the tab. This one doesn't. Set a wake-up time, pick at least one delivery channel — Telegram, browser push, or email — and the reminder is scheduled server-side so it fires whether or not the page is still open. Optional in-tab sound plays a short bell when the time arrives, but the real load-bearing channel is push or Telegram. Browser push works on Android, macOS, Windows, and iOS PWAs. Telegram works everywhere there's a Telegram app — phone, desktop, watch — and arrives as a regular chat message you can swipe. Use the alarm to wake up, to leave for the airport, to remember a daily medication, or to time-box a deep-work block. The label you set becomes the notification text, so when you wake at 6:30 a.m. you see exactly why you set it: "morning run", "flight check-in", "insulin". The widget remembers the time you picked across reloads in the same tab. Want to wire alarms into chats, family contacts, or repeating schedules? The reminder hub layers escalation and recurrence on top of the same primitives.

FAQ

Will the alarm fire if I close the tab?
Yes — pick browser push or Telegram as a channel and the notification is delivered server-side. The in-tab sound only plays if the tab happens to be open.
Does this alarm work on iPhone?
Yes, with two paths. Telegram delivery works in any iOS Telegram app. Browser push works on iOS 16.4+ if you add RemindMeNow to your Home Screen and open it from there.
How do I make the sound louder?
Browser-tab audio is capped by the OS. For loud, lock-screen alarms use Telegram (a phone notification with sound) or browser push to a phone where you control the notification volume.
Can I set a recurring alarm?
The dedicated alarm widget fires once at the next occurrence. For daily / weekday-only / weekly repeats, use the reminder section which has full recurrence rules.
