Hi all, solo/indie developer here, based in Japan. Garmin's own merchant system isn't open to JP-based developers yet, so I've been shipping paid features through a third-party processor (KiezelPay) instead. Wanted to share what I've built so far:
Aurum, a black-gold / rose-gold luxury watch face with 5 dial designs and metallic gradient rendering.
Cairn (free) and Cairn Pro (one-time $2.49 via KiezelPay), a hiking-focused data field: elevation, ascent, grade, VAM, and, on Pro, an on-device sunset countdown computed from GPS with no phone needed.
Overwatch, a watch face that automatically swaps layout based on context (activity in progress, sleep, etc).
All four are live now across roughly 30 devices (fenix 6/7/8, epix 2, Venu 3, Forerunner 265/955/965, and others). Links:

Happy to talk shop about the KiezelPay integration if anyone else is hitting the same JP-merchant-account wall, or about the DataField grid-rendering approach behind Cairn. Feedback welcome.
