Clock to use when giving presentations When I give presentations, I have to keep an eye on the clock to make sure my speech does not take more than alloted time, or in the end to know whether I can take more questions.

Looking at my watch is inconvenient, I would prefer my Android phone's large screen to:


Just display the time (for example 14:28).
Not go into standby mode.
Hugest font possible, black on white, landscape.


Sounds trivial. Is there such an app?
Priority to free apps, biggest priority to open source apps.
Digital Clock does almost everything you ask. Ignore the rubbish picture from the page, it is a full-screen clock with white text on black and it's free.

To configure it as you need, launch the app, then open the settings (tap the screen to open the options then tap Settings) then set:


Clock->Screen timeout to unchecked.
Clock->Orientation to Landscape.
Time &amp; Date->Show date to unchecked.


You can also adjust the time format and colour if you wish. The time is about half the screen height, but I can easily read it on my phone from more than 20ft away so that may not be a problem.
