Hey @ThomasGugler thanks a lot for the offer 🙏. For now I’m not planning to open the source, but I really appreciate your interest and I’ll keep it in mind for the future 🙂

Hi @Inakiarroyo and thanks for the feedback, so you are saying the limits of the API cannot show a message on subintervals, something like this? Hopefully it is something David can look into.

I talked with @david while ago about this, and he mentioned the possibility of adding an endpoint to list chat\_id’s with unread messages… but it’s still not possible 😃. Maybe, @david, is this something that could be implemented?

I am busy adding some chat related endpoints to the public API. Should be deployed Sat AM.

- GET /api/v1/athlete/{id}/chats
- GET /api/v1/chats/{id}
- GET /api/v1/chats/{id}/messages
- PUT /v1/chats/{id}/messages/{msgId}/seen
- DELETE /v1/chats/{id}/messages/{msgId}
- POST /v1/chats/send-message

It would be great to have chat support in your app. I am also going to be adding chat related webhooks.

Hey @david, thanks a lot for your response and for the API additions 🙌. However, those endpoints seem to be related to the chat feature. What @Simon_O and I are referring to are the messages associated with an activity. As of now, the only endpoint I’ve seen defined (and am currently using) is: `GET /v1/activity/{id}/messages`

The messages associated with an activity each linked to a per activity chat with type=ACTIVITY.

The `GET /api/v1/athlete/{id}/chats` endpoint returns “List chats for the athlete, most recently active first” and “Only returns activity chats that have new\_msg\_count \> 0 or that have been updated recently”.

Hi. Just wondering if displaying distance/pace units based on intervals.icu was still in your roadmap. I tend to use miles for distance and pace which I’ve set up intervals.icu to use. Thanks.

Just started using intervals and found subintervals app.. Saying this as a programmer (game dev) very well done! I’m still poking around in it so I may have missed a way to do this.. But I would like to be able to upload activities (FIT) directly from my SuperCycle ride tracking. So that I can skip doing a phone=\>computer=\>intervals steps.

Gracias Iñaki, great job!

I’d like to ask you for a feature, maybe it’s easy to do it and helpful. Let me explain you, I use to include notes on my trainings with links to get deeper information, but I can see there is no way to click on the links or even copy.

it’s just a proposal, consider if it makes sense to you and if it could be possible.

thank you

Hey @Grafik_Robot, thank you so much for the feedback, I really appreciate it. If you have a moment to leave a review on the Apple App Store or Google Play Store, it would help me a lot.

I wasn’t aware of SuperCycle before, but it looks really nice. I’ll look into adding support for uploading FIT files directly so you can use subintervals → intervals more easily. I’ll work on integrating this - thanks again for the recommendation!
