Excellent and useful! I wish I had a smart watch to put it on but it's good on my phone too. Occasionally the widget can glitch and turn invisible but it will come back. The outside clock face numbers are only black? Can't see them on my background and can't figure out how to change them. The widget palette is great, but I can imagine customization with background images of clock faces, different hand shapes, and/or color gradients to make it look really impressive!
