Constantin: monitor effort drift against your session average

[Łukasz Szmigiel]

@Stavrogin thanks for extra info. A guide is de facto an S+ app. So you had Constantin + Guide (2 apps). But it shouldn’t crash the watch nevertheless. Suunto watches are pretty clever and if they see that there are no resources left, they will kill non essential apps, it’s hard to crash the watch and the latest version is simplified.

I’ll do some more digging into optimising the issue but the problem is that on S9PP when I’m using navigation and 2 S+ apps, current version doesn’t hit the limit. I’m surprised that the issues happen on V2 which is newer hardware.

Perhaps @suuntopartnerteam can shed some light on it?

But just to clarify - it didn’t crash at the beginning of the run but later, when you were cycling the screens, right?

[Stavrogin]

@Łukasz-Szmigiel That is correct. The freeze and reboot was triggered by cycling through screens. I feel like that was what happened with the HexHunter app as well.

[Łukasz Szmigiel]

@Stavrogin it seems to me that the UI is still too heavy and, perhaps, tries to do all the painting at once after the screen cycle. I’ll let you know after I release a new version with delayed rendering and we’ll see if it helps.

[Łukasz Szmigiel]

@Stavrogin new version should be available now in SA, you may want to give it a try. The code is ~25% smaller in general and there are some additional optimizations added to how the UI drawing is being handled. If that still crashes - I’m afraid I can’t do much without the support from Suunto or logs from V2 running the app

[Stavrogin]

@Łukasz-Szmigiel thanks and I will give it a try

@Stavrogin Did you enable or disable Always-On Display during activities?

[Elmiuel]

Hi everyone, I’ve also been testing Constantin because I’m interested in its setup. I have a V2 and initially started with 3 Suunto Guides (too many, several were faulty), then I switched to 2 Constantin guides and a 3rd grade training guide… also… the watch would freeze or the Constantin screen option would remain BLACK.
If you also use it in conjunction with ZoneSense, it also fails. I don’t think there’s compatibility yet with multiple systems (3 guides + activity and data watch) working outdoors… Suunto could refine these guide options, which are, in my opinion, quite interesting. Thanks, Luckas️

[Łukasz Szmigiel]

@Elmiuel thanks for your report. If you haven’t - check the current version (updated yesterday in the evening) - I’m getting reports that it’s more stable on V2.

When the particular SuuntoPlus app goes dark it means the watch unloaded it. You can confirm it by going to workout settings during the workout and checking active apps - the uploaded apps should be off.

[Stavrogin]

@Łukasz-Szmigiel I loaded it up and was able to start an activity. However when I hit the lap button Constantin disappeared the first time I tried. On the second attempt I was able to keep it on the screen. Looks like it might be fixed.

[Łukasz Szmigiel]

I’ve been able to release a few updates oriented around lowering the hardware load of the app and yet even today I’ve received a feedback that the app is rebooting the watch - and it’s always Vertical 2.

Are there any known issues or something that’s not specified in the documentation in relation to Vertical 2? @dimitrios-kanellopoulos , @suuntopartnerteam ?

Can I help somehow in debugging the issue by adding extra logging, etc.?

[Łukasz Szmigiel]

Constantin 2.02 is out

Quick update for anyone running Constantin, the steady-pacing SuuntoPlus app.

With the 2.x line everything now lives on a single workout screen — pace, heart rate, their trend lines, and your current heart-rate zone, all visible at once. No more switching views with the upper button.

Also, the trend chart zooms in tighter, so a slow drift in pace or heart rate is much easier to catch early — while big swings still fit on screen. If you tend to fade gradually, or your HR creeps up while your pace still looks fine, you’ll spot it sooner (although it may require more fine-tuning for slow drift).

Works on UI2 watches (Suunto 9 Peak Pro and newer). Feedback and bug reports very welcome. I hope that this time it’ll work smoothly with V2 as well.

Happy running!

@Łukasz-Szmigiel this is my favourite app and with me every base run.

Thank you!

[VoiGAS]

Sounds like a great app - unfortunately I don’t have a lot of flat tracks available… is live NGP also possible for the Pace value?

[Łukasz Szmigiel]

@VoiGAS I’m investigating it. Also speed for biking instead of pace. I mean - it’s possible, why not. The issue is if the platform will handle it all.

[Łukasz Szmigiel]

@althaea35 thanks, I made it to help me avoid pushing too hard on my runs. My migraine doesn’t like too high effort and hr. Glad to see it’s useful for others!

[Łukasz Szmigiel]

Welp. Here we go again. I’m investigating zapps being unloaded when Constantin 2.0+ is being used with ZoneSense. It seems that the S+ app can be either custom designed or have custom features but not both

[Łukasz Szmigiel]

It’s quite likely that 2.05 will finally be stable when running along ZS and navigation. I’ve uploaded it to Suunto platform but the file hasn’t been updated yet.

If you’re seeing a big, white dot on the screen instead of two-color arch - it’s 2.05 or newer.

How To Use
Start your workout

Hello
i have a route I do my Trailrunning,
i think it would better fit then the ghost runner.
but, have it installed but can’t find in my watch.

have a nice day
vinc

[Łukasz Szmigiel]

New version is in.

The good:
There’s speed as default, pace for running and ngp for trail running.

The bad:
Used along zonesense and navigation crashes the app (the watch unloads Constantin to free UI memory).

So… Let’s see how far I can optimise it. I suspect I’ll have to remove the HR arch and the white center point as a minimum to make it stable.

@Łukasz-Szmigiel Just wanted to test it this morning.
I use Runna for training plan generation and started a workout + Constantin which ended in a crash and reboot.
I just started the activity and wanted to toggle to Constantin.
1st page, standard overview (pace, distance, etc.), 2nd page map, 3rd page would have been either Constantin or the workout/ interval view. Not sure since the watch stalled and then rebooted.
