SuuntoPlus Community Apps: end of the hype…
-
Disclaimer: this is my personal take. I don’t know how widely it’s shared, feel free to share your thoughts.
I built a couple of apps to support my training by adding features not available in Suunto’s native screens.
But if they are not “certified,” they get deleted every time I sync the watch with the app, and for me that happens multiple times a day.So these apps become unusable, because they disappear every time, and reinstalling them requires going back to the PC, connecting the device, and rebuilding again.
It’s manageable at the beginning (the hype phase), but then it becomes a hassle and all motivation to develop apps fades away.
When will we be able to have our apps persist on the watch?
-
@Manuel-Extreme I mentioned this before as well. There should be a setting to make an S+ app, or a custom watchface persistent through syncs.
This might need support from the Suunto app, adding separate section to manage (view, settings, remove) these unpublished custom apps and watchfaces. -
@Manuel-Extreme
Can’t you just submit the apps to Apizone and download them from the app? Then also everyone else could use them if they are useful. -
@Pottu I am not authorized…

Once the app is pushed via the vscode it should persist and be visible in the Suunto App as custom with ability to delete it from there. That would make the development easier too.
-
I think best way to keep custom apps would be to import the plus apps into the Suunto phone app. Then transfer it to the watch. This way you would not need to pair PC and then app again after testing and the plus app could stay on the watch. I don‘t know if this will be possible…

@Manuel-Extreme , @squirrel , @łukasz-szmigiel , @chus1962 :
I captured the bluetooth packets and had an llm reproduce the protocol. Debugged for a bit and now the attached ANDROID apk can send all your custom apps at once to your watch after a sync has removed them. Works on my race, don’t see why it wouldn’t on others.
Instructions:
- pair your watch with your phone (duh)
- move your apps to your phone storage
- inside this app, select 1 watch app package at a time or have all of them in their own directory, which you can select as a whole
- ‘‘scan and connect’’ within this app
- the apps will appear on your watch
Hopefully this eases your life a bit
ofc suunto may at any point change their protocol, but I don’t think they will: app-debug.pptx (You need to rename the file to .apk, the forum only allows a limited number of extensions)Edit. if the app does not connect, make sure you aren’t connected to something else like VS Code for example. The app has few permissions and no internet connection btw

Edit 2. Here’s the repo if you wish to build it yourself. At the top you can see “tree”, which shows the root of the repository where you can find the pre-built binary.

@SyncBypass
great work for you and LLM.However I reported the issue and suggested how Suunto should solve it properly. Hopefully it will be done in the future.
But I cannot allow distributing executables on this forum since we cannot verify it’s safe. Also you just created your account, so I cannot trust it.
Either publish your app via Play Store or share source code on public repository and give a link to it.Take your time, but if you don’t do this by the end of the week I’ll delete your message.

@pavel.samokha Understandable. Will make a repo
