I'm a co-founder at Fewlaps, a mobile software company and I am a Garmin user too.
I've used a lot of watch faces, and we decided to create my own one and upload it to Garmin connect.
It has had good acceptance, and more than 3K downloads in less than 5 days, incredible!
A lot of users has asked for a dark theme, so 4 days after the first version, we've just published an update with the dark theme
