If you sleep through everything and need an alarm that forces you out of bed, Alarmy is built for that exact problem. If you want a free, no-install alarm for naps and desk wake-ups, Alarm.now is the simpler tool. They solve different versions of "I overslept."

Key points

  • Alarmy is a phone app that makes you do a task - Scan a barcode, solve math, take a photo - To shut the alarm off.
  • Alarm.now is a free browser alarm with no app and no account, but the tab must stay open and the device awake.
  • Pick Alarmy if you snooze through normal alarms and need a hard wake-up mission.
  • Pick Alarm.now for laptops, work computers, and quick naps where you don't want to install anything.
  • Be honest: a browser alarm can't wake a sleeping laptop, so it's not the best no-fail morning tool on its own.

What problem are you solving?

People who oversleep usually fall into two camps. Some need a wall between them and the snooze button - A reason to actually stand up. Others just forgot to set anything, or their phone was dead, and they want a fast backup.

Alarmy is for the first camp. It won't go quiet until you finish a "mission," like walking to the kitchen to scan a label or solving a few math problems. The idea is simple: by the time you've done the task, you're awake.

Alarm.now is for the second camp. Open a tab, set a time, done. It's great for catching a nap or a desk wake-up, and you can stack a few alarms as a safety net. Here's how to set multiple alarms at once for that.

Side-by-side comparison

Alarm.now Alarmy
Type Browser webpage Phone app
Cost Free Free with paid extras
Install / account None App + account
Wakes a sleeping phone No Yes
Forces a task to dismiss No Yes (its main feature)
Snooze Optional Limited on purpose
Works on any computer Yes No, phone only
Multiple alarms Yes Yes
Tracks your wake habits No Yes
Best for Naps, desk wake-ups, backups Chronic over-sleepers

The big gap is the "wake-up mission." That's Alarmy's whole point, and a browser alarm doesn't have it. So if you can silence a normal alarm in your sleep, Alarmy is built to stop you.

Where Alarm.now wins

There's plenty Alarm.now does that an app can't:

  • No install. Works on a locked-down work laptop where you can't add apps.
  • No account. You don't hand over an email or set up a profile.
  • Cross-platform. Same tool on Windows, Mac, Chromebook, or your phone's browser.
  • Quick backups. Set a wake-up and a second alarm a few minutes later. A single miss won't sink you.

You can manage the whole stack from the my alarms page. And it doubles as a timer or stopwatch when you need those.

The honest limits of a browser alarm

I won't oversell this. Alarm.now runs in a tab, so a few things have to be true for it to ring:

  • The tab stays open. Close it and the alarm is gone.
  • The device stays awake. A laptop that sleeps on battery kills the countdown.
  • The tab stays unmuted and the volume is up.

For a deep sleeper crashing into bed, those rules are a real weakness. A phone app like Alarmy rings on a locked, sleeping phone - A browser can't. If you still want to lean on a browser alarm overnight, read how to keep your browser alarm running overnight, and grab the deep-sleep tricks in waking up as a heavy sleeper.

Which should you pick?

If your real problem is hammering snooze and falling back asleep, get Alarmy or a similar mission-style app. The forced task is the feature you need, and a browser alarm can't copy it.

If you mostly need a fast, free alarm for naps, study sprints, or a backup at your desk - And you'll keep the screen on - Alarm.now is the lighter, friendlier choice. Many people use both: the app for the morning that can't fail, the browser for the rest of the day.

TL;DR

Alarmy is built for chronic over-sleepers because it forces you to finish a task to turn it off and rings on a sleeping phone. Alarm.now is a free, no-install browser alarm that's great for naps and desk wake-ups, as long as you keep the tab open and the device awake. For deep-sleep mornings, lean on a phone app; for quick everyday alarms, the browser is simpler.
