My laptop is always on 24/7 downloading content or uploading videos. Early flights mean I cannot oversleep. Though my phone has an alarm, it always fails to wake me up. Found this simple site that allows you to set an alarm.
Kukuklok is a website that offers a free online alarm clock ! Not exactly ground breaking, I know but I like it cause my laptop is way louder than a mobile phone.
The site is very simple, set a time, choose a tone for the alarm and set the alarm. Once the alarm has been started, it does not require an internet connection.
To turn off the alarm I have to wake up and open the laptop, so it hasnt failed me yet. Overall a simple app but deserved a mention cause I like it !!
