LED Watch 3000 will work on watches running Wear OS, as well as ones running Android Wear.
It will not work on Samsung Gear watches running Tizen, which is almost all Samsung Gear watches. The sole exception is the Samsung Gear Live, which runs Android Wear.
I’m not a huge software shop, I’m just some dork with a laptop that writes code in some of his spare time.
LED Watch 3000 uses Keshikan’s “DSEG” 7- and 14-segment fonts.
LED Watch 3000 is free and open-source software available under the GNU General Public License, version 2.
