The widget wasn't working, but then the creator figured out that the problem was a setting regarding battery optimisation. And now it works perfectly. So does this mean that it will be possible to add a second hand? Also, I would like to request an inverted-colour version, with white numbers on a black face.

This is a great app, i was interested in Decimal time, but can you include time in multiples of five ? 20 hours in a day, 50 minute in an hour and 50 seconds in a minute...would be really helpful if you include this format in the app

My favorite clock app. I install it on every android phone I buy. I can live without it, I just don't want to.
