CMF Watch Pro Watchface SDK: Upcoming community initiative

RapidZapper · 2024-02-12T14:58:26+00:00

After months of work, I’m finally confident enough to say that we’re going to have Community-made Watchfaces. While most of the work over the last few week...

Interlastic

MarkG13 Since he isn’t replying rn, i can answer myself 😃

For both watches yes.

He hasn’t said anything about that yet, but I imagine it has all the features a normal watchface can have.

RapidZapper

Interlastic It should indeed have support for most features you can have on a watchface, lot of specifics I can’t detail yet but it should be really complete in the end

MarkG13

RapidZapper Thank you for your reply, I look forward to seeing what you are planning when it’s ready. If it will be possible to customise a watch face with the features you want it will mean I might not need to continue my quest to have the distance in miles or Kms restored to the app.

Also, thank you Interlastic for your earlier response, I appreciated it.

Will it work on Watch Pro 2?

RapidZapper

JoeDissolvo Yes

JoeDissolvo

RapidZapper heck yeah. Thats awesome.

RapidZapper it’s only a matter of finding a good way for users to install Community files.

Gadgetbrigde has an option for uploading files. Could you share information about the file structure of a watch face or even a watch face file?

RapidZapper

jak2k That’s an option i’m considering but it’s certainly not the best way for the average user to install these since you still need to get on some stuff that aren’t easy for everyone

Hey,
A quick update on the project progress.
Since my first post, Watch Pro 2 was released, and good news it should be compatible since it simply use an updated version of the watchface system used on Watch Pro 1.
Watch Pro 2 got some new features on the Watchface system and we’ll explore that part next year.
For now focus in on Watch Pro 1 with a lot of progress.

Our first Watchface made from scratch for Watch Pro 1

This Watchface is based on Mysticat, an original Watchface concept by @BrandonPaul for Pebble

It use some of the different mechanics we can now use like:
- Display elements during a certain interval (6 different cats will be shown at an interval of 10min)
- Display digital clock with our own font
- Display a static background
  
  This is very basic but an amazing PoC to test our capabilities and understanding of the watchface format.
Another major project is Watchface studio

While we weren’t able to deliver it this year as planned, we made some progress on a core part, the preview part, it’s a simulator that should be 1:1 to the Watch behavior once completed, it’s working on the web and use local elements like your PC time to preview a realtime configuration, you can also set custom values for the various element shown on your watchface to test it without having to send the watchface to the watch to get a preview.

As you can see above, this is a preview of the simulator, we’re still working on the details but it’s mostly ready at least for Watch Pro 1, Watch Pro 2 will be part of it later next year.

This tool is a core part to help define specs of the watchfaces for the upcoming edition tools.
How do we install watchfaces?
Well that’s the main problem we’re facing right now, while there is some alternative solution to install watchface, they involve Root/Adb log which isn’t an easy solution for everyone especially for those without a PC, we’re working on that topic and we’re trying to find a solution to get any CMF Watch owner in the Community either as a developer or as a user.

Feel free to ask any questions in the comments.
See you next year!

RapidZapper so cool to see mysticat in its natural habitat again!

RapidZapper How do we install watchfaces?

Hmm, so I don’t know if you want to install watchfaces by acting as the app, or modifying the cmf watch app to include more watchfaces. What you could (maybe) do, is give out a APK that injects / edits code in the cmf watch app.

Also, can you give us an Idea on how the creation of watchfaces feels?

Interlastic

RapidZapper made me think about something… Have you figured out how to use the color and function settings for the watchfaces?

RapidZapper

Interlastic Actually the app before Watch Pro 2 was easy to mod (js bundle) so that was the plan, since then it’s using bytecode which make things way more complicated so that’s out of scope for now, what we really need is just a “select file” option in the watchface library
As for watchface creation, that’s still tbd, for now it’s just me making everything with hex editor

Anonymous142

don’t get me wrong here I applaud the initiative but I also wonder how far it can go without actual official support from Nothing? in way of docs for the file format and other spec details without having to reverse engineer everything. It takes time to make and build the tooling and is there a danger it can be out of date should Nothing change something in an update. This was started when watch 1 came on the scene and now we have watch 2. For all we know we have watch 3 coming. Maybe if the current stuff was just chucked onto GitHub as is and community could help would get faster traction and adoption? Like say amazing work 🙏

RapidZapper

Anonymous142 We really just need a way to install the files, we got pretty much everything else

Interlastic

RapidZapper Are the existing watchfaces seperate files, or are they hardcoded?

SebiAi

RapidZapper I am not familiar at all with the ins and outs of the CMF Watch series so excuse me if this comment is not relevant but I still want to mention it.

Regarding the patching of the app: ReVanced has a pretty fleshed out system for patching apps including resources and such. Maybe you could piggy back of that?

Oxytocin✨

Hey…i’ll be happy to participate as a user if you want…🙂

Rahul

Great work, Thomas! It’s exciting to see this project coming together!

RapidZapper

SebiAi You still need to make the patch which is the part that’s now not really possible

RapidZapper

Interlastic not yet, seem to be certains color used as marker to be replaced, will have an extended look next year, focus is for a v1 for Watch Pro and basics for Watch Pro 2
