After searching for a long time for a watch face that displays recent heart rate activity I ended up creating my own. It's quite simple: steps, distance and HR displayed at the top, battery level in the bottom corner. Magic is in the background - HR activity graph updated every 30 seconds (so on one screen there's represented over 1h of recent HR activity).
Creating this watch face actually showed me, why there's not much other watch faces with graphs - Fitbit hardware is very limited when it comes to drawing things. A lot of data points and requirement of fetching heart rate constantly (even though I'm using batches, then using mean HR value for last 30 seconds), basically pushes hardware to its limits.
I'm currently working out some performance issues that are actually visible only after first run of the watch face (takes about minute to first show up after installing). Other than that I'm enjoying it myself and battery usage seems pretty good (about 3-4 days on one charge), delay after switching from other apps also seems fine on my Versa.
I'm not sure when exactly I'll have some time to work out performance issues that are blocking this watch face from publishing in public gallery, but if someone else waited for something similar and will enjoy this watch face just like me, there it is 🙂
