Stryd S+ app

[lexterm77]

@TyreseJ4

I got stryd model 26 firmware 2.1.29 and s9pp with 2.22.60, and suunto smart belt. S+ burner app. When i make a pause i get tons of dropouts, when no pause i get a few. Sometimes none. I pass under several 0.7 million volts power lines about 30 meters above my head.
Edit: stryd on right foot, watch on left arm.
I had dropouts since s9b, used foot stryd and foot stryd wind devices. I lost wind device replaced with a new one, still dropping, also used suunto 9p, s5p, s5. Droputs not visible on SA or runalyze, only stryd web site.

@lexterm77 Yeah that’s what I mean. The dropouts only show in the STRYD app.

@Brad_Olwin I use my watch on left arm and STRYD on left foot. Btw, here’s an article from STRYD in reference to this issue: https://support.stryd.com/hc/en-us/articles/360044464113-Stryd-power-drops-when-running-with-Suunto-watches They say Suunto is to blame. And when you compare results from Suunto and STRYD’s offline sync, it appears they are correct with their assessment.

I have also some dropouts on my power curve on Stryd app

Those are not big ones so I guess it doesn’t bias too much the analysis of the run. It is just not aesthetic

What would be the purpose of the S+ Stryd app ? Display Stryd metrics and zone using Suunto native power or Stryd one if coupled ?

[Egika]

@v-sacre the Stryd+ app has all Stryd metrics in one dedicated screen, like ground contact, vertical oscillation, power, etc

[herlas]

Not sure how the final S+ STRYD app will work, but it seems to me like those STRYD metrics are not something I look forward to visualizing during the workout, rather only for post analysis. To me, STRYD structured workouts are something I’ll be more hype to have on my watch and they have plenty

@herlas

I would very much like running economy on s+ app than ground contact time, springiness of my steps etc.
thats what I used to use in MC on A3P.

RE [kg/N] = Speed [m/s] / Power [W/kg]

Now that error bars are much lower on stryd it would actually mean something. I would also like vector components for vertical forward and lateral forces separated.

[herlas]

@lexterm77 I’ve seen that metric on runs synced to Runalyze, they also have the efficiency index EI = Speed [m/min] / Power [W].

I like those for post analysis and tracking the value trend over time, not sure how useful they’re on the fly run I’m surviving my next 5K

Let’s see how things are implemented, but as stated, hope STRYD structured workouts do come to Suunto one day.

@herlas

I want RE during the run, not after. During a warmup at flat constant power. Then RE it would tell me if I should take a longer run or take it easy and do recovery run.

[herlas]

@lexterm77 that’s cool. Stryd doesn’t currently have such metric, hopefully there’ll be a end-user S+ editor of sorts

[isazi]

@herlas so the official S+ Stryd app will not have metrics that Stryd doesn’t have, but Speed/Power is already possible to compute right now. I can test the idea and tell Suunto there is some interest in this.

[lexterm77]

@isazi

Or have s+ app where we can enter our own equations and play with them

[herlas]

@isazi right, having STRYD metrics on S+ screen is fine and people have requested, but IMHO for me I use/check them for post analysis and that I already do on powercenter, rather than on the fly. Do you know if there’s another benefit from the STRYD S+ app? Like i.e. minimizing the 7 sec gap to receive power on our Suunto?

Things like STRYD structured workouts or enabling the new running profiles from the new STRYD sounds too tempting to have on our Suunto watch

Either way, will still be happy to see the integration happen when the STRYD S+ comes out

[isazi]

@herlas I think the advantage for users will be seeing some metrics in real time, and have them also saved in SA for analysis.

I will implement the efficiency S+ app during Christmas holidays just for fun.

[DMytro]

@isazi just to clarify, you have an acces to API, but regular users don’t? As there any chance to get an acces if we contact support or sb else? No need for a fancy interface, raw code will do just fine.

[isazi]

@DMytro not sure if the plan is to open access to users, or just third-party companies working with Suunto. I have access to the development environment (like others, also on this forum) mostly for testing, but I can develop apps (I developed few basic ones for fun).

[DMytro]

@isazi no fair!

[taziden]

@DMytro Indeed. I’m starting a public protest in my town! Dev tools for *

[DMytro]

@taziden wait for me, I’m printing a banner.

[isazi]

What can I say is that we started with S+ apps being part of the firmware and only Suunto being able to develop them, to now where they are developed with a VSCode extension available to third-party partners of Suunto. Maybe Suunto will open this to other users at some point, but you know that this requires effort and resources on Suunto’s side, so it may take time.
