Pretty but not the most functional imho (although that's probably not the point):

We seem to be obsessed with time related apps, considering this app and our Rise Alarm Clock. Timeless is an experiment in creating time visualizations. We will be evolving the app with new, distinct visualization themes—ones that perhaps change with environments or between time zones, etc. The next obvious way to extend the product is with watch faces for Apple Watch, once that opens up. Thank you for the feedback!

I downloaded and used. It's beautiful but it took me a while to actually register the date, calendar and time. Beautiful interface.

This clock is beautiful, but it takes time to know what time without read the text.
