I started working on upgrading Octowatch to be compatible with Pebble API 3.x as well as the new round watches and I've got my work cut out for me. I'm very excited about the idea but I think it's going to be a considerable re-write, so it's probably not something I'm going to complete quickly.
The upside is that I want to incorporate a number of improvements that would have been hard to retrofit, so the next version should be considerably better. I want to add support for multiple printers, more feedback and timeline integration, to name a few.
If you've used Octowatch and have some features you'd like to see in the new version please pass them along.
