Description

All in one extension to manage your schedules. You can define multiple alarms, use the stopwatch with as many "lap"s as required, or simply use the timer with pause and resume support. This extension uses the built-in API to set alarms hence the extension works even if the UI is hidden or your browser gets restarted. This extension offers alarm sound snoozing which snoozes the alarm sound 3 times with a 5-minute delay. The extension displays a high-priority desktop notification when either an alarm or a timer is fired, also it plays two different sounds to get the user-attention. As of version 0.1.3, the user can snooze each notification with a 5 to 10-minute delay. As of version 0.1.4, you can export and import your preferences

Nice set up, but the alarms do not always go off. No use if i don't get reminded. Sometimes it works, sometimes it doesn't.

This app does NOT spring forward one hour for every alarm I use last Sunday. Needs to be fixed.

it never worked, it would always have the pop-up pop up late! but i'm not sure if it's my computer or not.

Keeps setting date for a week ahead. Not very useful if there isn't a calendar function that allows you to choose the current date.

After the left click on the extension, then the click on "alarm, timer and stopwatch", i just end up in your website where i can do NOTHING to set up an actual alarm. I have to wake up in 3h, thanks for the f**** time wasted deleted

The only problem with this is after you set an alarm, it's not automatically on. You've to toggle the on switch. And if you forget to do so (like me) then you'll miss an alarm you never even realized wasn't turned on!

It works. I can't for the life of me understand why these countdown apps are ALLERGIC to multipler Timers but will show they're capable of it, like having multiple alarms possible at once. Add multiple Timers option, and I'd change this to 5 stars easily. Interface is lovely. Settings, very nice. Just doesn't do the ONE thing I needed it to.

There is a place for a description; but after you put one in; it doesn't show up in the batch of alarm choices so that's no help; and it doesn't show up when the alarm rings; letting you fend for yourself with your own memories as to why the alarm rang; EVEN THOUGH THERE'S A FACILITY TO HELP REMIND YOU WHY IT RANG..

I am struggling to figure out how to determine the difference between AM and PM.

It's not bad, but there is no option to edit an alarm after creating it. You have to make a new one and delete the old, a bit annoying
