The Best Free Online Alarm Clock — Everything You Need in One Place

FreeAlarmTimer.com was built after testing every major online alarm clock — vclock, onlineclock.net, setalarmclock.net, timeanddate.com, alarmdj and more. Each one had something missing. None had all the features that someone who actually uses alarms daily would need. So we built this.

Upload Your Own Sound from Your Device

Every other free alarm clock forces you to pick from their small list of built-in sounds. Here, you can upload any audio file — MP3, WAV, OGG, M4A up to 20MB. Nasheed, motivational speech, your favorite song, or a voice recording. The file stays in your browser and is never sent to any server.

Math Challenge Mode

Forces you to solve a math problem before the alarm stops. Choose Easy (addition), Medium (multiplication), or Hard (multi-step). Your brain cannot solve math while still asleep — so this guarantees you actually wake up. Works extremely well for heavy sleepers.

Gradual Volume Wake-Up

Waking up to a sudden loud alarm is jarring. With gradual volume, the alarm starts quietly and slowly gets louder over 30 seconds — a gentler, more natural wake-up.

Works on Every Device Without Any App

This alarm clock runs entirely in your browser. No download, no installation, no signup. iPhone, Android, Windows, Mac — everything works the same way. All buttons are large enough to tap comfortably even when your eyes are barely open.
