If you want to know when it’s time to go bed…
Here’s an application that adds a clock on your tablet.
(The button is also a web browser if you click on it.)
Available in 2 formats: 24h and 12h am/pm
That won’t be available on the Marketplace. Apparently, this app is too simple to be accepted. (An it was to be free.)
So now you know. it exists.
