Alarm Clock


Free version limits

In the free version, you can create only one alarm (template or active) at a time. Remove the limitations to create an unlimited number of alarms.

localStorage


Active and saved alarms are stored in the browser via localStorage — meaning the data stays on this device and isn’t sent to the server. If you refresh the page, the alarm will continue without changes. If you close the tab and open it later, the alarm will recalculate the remaining time based on real time. If there are multiple alarms, the logic doesn’t change. But set alarms won’t be saved if you clear site/browser data or use incognito mode.
Description

Create an unlimited number of alarms with a full set of settings. One-time and repeating alarms, saved templates, melody selection, quick start — everything in the browser, no registration. Saved templates will always stay up to date regardless of the repeat mode — dates will shift automatically. For reliable operation, keep the tab open and disable aggressive power saving for the browser.
