Constantin: monitor effort drift against your session average

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!

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?
-
@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.
-
@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!

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
-
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 workoutHello
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 -
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. -
@lessthanmore yeah I know. Check if you have today’s version on your device. It should be 21.06 and 2.08. It should be fixed.
