Just works like a timer and is good! Just works like a timer and is good, so they just work basically how you expect it to work and you can add the message which is pretty nice. Overall this is quite very simple but would be nice if they added some more either way it's good/fine so thanks! [Oh and yes it's helpful]

It worked very good and on time twice… It worked very good and on time twice back to back for me unlike those other online alarm clocks that had stopped working for me.

It works great I use it as a school… It works great I use it as a school alarm and also I am using this on a Chromebook and sometimes while the alarm is on the screen cuts off so now I am late for school and missed my test but with this alarm, you don't have to worry about ..... Great source of an alarm

A proper alarm. Alarm activated on the second it was supposed to and hurt like hell when I had on max volume and didn't turn it off.

this alarm works exactly as intended... unless your computer doesn't stay lit all night long this alarm works exactly as intended. unless your computer has some sort of sleep mode function, because the alarm stayed totally silent until i clicked my mouse two hours after I was suppose to wake up for school.
