2pi Pulse Halo Analog


A minimal + fast analog watchface that draws your heartrate history as a radial chart.</p><p></p><p>Data is beautiful. Turn your pulse data into personal art on your watchface. You’re the artist.</p><p>A reminder that time is not a straight line. But a dimension with no beginning and no end.</p><p>As the chart sweeps around the clock, new data erases old data. Nothing is forever & tomorrow’s a new adventure.</p>

What’s New

This watchface is fully functional and supports all the features forever. There is no trial period and no expiration date.</p><p>But, if you’d like to customize the colors, please leave a review and contact me for an unlock code (click Contact Developer or email me at [email protected]). It might take me some time to reply, but I will reply. Thank you for being patient. Donation is optional but very much appreciated -- it lets me know you value the engineering in a watch face that looks good, runs fast and sips very little battery:</p>

Very unconventional watch face - but fascinating :-) I‘ll try for some days - let's see how I can deal with it ;-) Will contact you to unlock colors, otherwise it’s difficult to distinguish the different numbers.

I love the watch face. I originally had difficulties with the colors. I reached out to the creator and he gave me an unlock code so I can edit the colors.
