When I upgraded to my FR965, the watch face I had been using on my previous watch was not supported. That ended up being a good thing, because I found this watch face! This watch face is beautiful and well designed. The developer was quick to respond to the questions I had. I highly recommend this watch face!

The Watchface battery consumption is incredibly low. It looks great on my 6x pro solar. The developer immediately responds to suggestions and implements them. My absolute favorite and worth a beer ;-)

Thank you Klaus!

Unique dial. The addition of a notification counter has made it even more useful.

So far, an interesting watch face, but it would be nice to have a few more data to choose from. Very unusual graphics, I like it. When it comes to battery drain, this is a world record. Stock watch faces use more electricity than this. Really good job.

Thank you very much Sebastian! I got your email about adding step and notification counts. 1) Step count: if number of steps is 4 digits, it's okay. But for people who walk a lot and have 5-digit step counts or above, it could be too wide to be displayed nicely. Meanwhile, "daily steps / daily steps goal" is an available option for the bar scales above and below the time. 2) Notification count. This is something I'd like to add in addition to phone connection status. But I still haven't decided where is a good place to display this information. If you have any suggestions, please let me know! XD

Lovely watch face. Not much to improve. Perhaps different fonts for the time.

Thank you Aslam! To minimize memory usage and keep within the minimal/fast theme, system fonts are used. Custom fonts will increase memory for every font and every digit needed. But I agree with you, having more custom fonts will be fun! I will consider your suggestion.

Very interesting and beautiful dial! To make it more convenient to use, please add the time left until sunset / sunrise (instead of just sunset), stress (as a scale or numerical value next to the heart rate) and the ability to swap data (place the heart rate under the time, and the date and so on above the time). There is also a lack of a separator for 4 scales, which makes them difficult to read. Thank you very much!
