Constantin 2.12 Steadier drift view, new detail screens, and a website Hi everyone, I’ve just published Constantin 2.12, a new version of my SuuntoPlus app for monitoring movement-speed and heart-rate drift during workouts. What’s new in 2.12 This release focuses on making the app clearer, smoother, and more stable during real workouts. Three switchable views Three views are back, but this time without the need of reloading the template: Drift — combined movement-speed and heart-rate trend Pace / Speed / NGP — movement-speed detail view Heart Rate — HR detail view The upper button switches between them: short press: next view long press: previous view All views share the same collected trend data, so switching views does not reset the chart. Smoother and more representative trend chart Trend values are now averaged over each recording interval during up to 10 minutes (four bucket, each 2:30 min average + “now” refreshed every 3 seconds). The chart now reaches further back and gives a broader view of how effort is changing over time. Better behavior when data briefly drops If GPS/speed data drops briefly, the chart should hold its history instead of clearing. When you stop moving without pausing the activity, the movement-speed trend holds the last valid sample while heart rate can continue updating. Shared scale for pace and heart rate drift In the combined drift view, both lines now share one visual scale and meet at the same point on the right. This should make it easier to see whether movement speed and heart rate are drifting together or diverging. HR zone bar appears immediately The heart-rate zone bar now appears as soon as an HR zone is active, without waiting for the trend chart to fill. More stable alongside navigation and other SuuntoPlus apps A lot of work in this release went into making the app behave more calmly under load, especially when used together with route navigation or other SuuntoPlus apps. Website with details I also published a small website with more details, screenshots, and explanation of how the app works: https://constantin.szmigiel.design/ Feedback is very welcome, especially from people testing it during longer workouts, route navigation, or together with other SuuntoPlus apps.

@sky-runner Tested today and multiple normal routes were synced during same activity. SV2 and Android, but some firmware and app versions ahead for testing. At least some hope…

@Stavrogin Personally I find this to be one of the big issues with Suunto, a watch that I am otherwise quite happy with. My understanding is that ”guides” are developed by partners from templates provided by Suunto. So if you want a change to the guide you have to talk to TP. Further the interval structure is embedded in the guide and downloaded as a package to the watch, but this structure is not available to other apps or data screens. Suunto has an API for upload of guides and FIT files, you can find documentation online. But this API is only open to partners like TP. Technically I think there are a number of things that should be done… Decouple the training structure from the guides Make the structure available through the Suunto os to othet apps and data screens Allow upload of FIT workout files directly via the Suunto app Wether Suunto will ever do this is probably more of a business decision.

Ldive A lot of us have had problems with the app and bluetooth sync, Somehow it looks related to language settings on the Nautic and phone, i’m putting all in english and had problems with my phone when in Dutch. After setting all on english, sync works flawless. So make sure they match. Start sync and the app should give you a green checkmark almost instantly when the Nautic is near and switched on.

@Woodster said: Let me know how I can send over diagnostics It is explained in the opening post of the thread?

@rémiP Same situation for me. My guess is that updating the app itself and/or the descriptive texts for the Suunto Plus appstore doesn’t require any moderation - while updating banners and/or the screen does. No idea why.

I’ve introduced a new setting for user weight. While reading from the watch user weight value appeared to work, it was causing issues when starting the SuuntoPlus app with any non-default rider position.

@Pigeon101 i had the same problem. but its like they say. just tap on the message and it disapears.

@duffman19 as someone who works with motors all the time, this is kinda difficult to stay away from magnets.

I have a Polar H9 (beside the strap is the same as a H10, just cheaper) which consumed batteries like creasy, but with the latest firmware update is fixed. I also have a Polar OH1+, which is an optical sensor you wear on your upper arm (or attach it to your swimming goggles). It’s an older model, but the sensor is the same as the new verity sense, just cheaper (although the verity sense has some extra functions, you might or might not need). Overall, optical sensors on watches never worked for me, but the OH1+ works pretty good. It is rechargeable, which I think is a advantage. Most of the time I find it slightly more comfortable than a chest strap, although, since your arm moves while running, there might be some need for readjusting the position

@Calando said: @LapaS Correct, for a guarantee-replaced device you get no new guarantee (just the remaining time - 1y guarantee, if you get a replacement after 8 months, the replacement will have 4 months of guarantee). Try another HR strap - two of my colleagues are using the Polar H10 and never faced any problems (they have Polar and Garmin watches). My H10 also still works perfectly with my Race 2 (see above). Another advantage of the H10 - replacement straps are more than 30% cheaper than the Suunto ones. In the meantime, I am unfortunately pretty much convinced that @sindavide was correct in his post above. I asked Suunto about warranty and since my original sensor was bought under a year ago they said warranty should cover the replacement device. So the device is now going to Suunto repair. Anyway my wife had a Polar H10 sensor lying around that had not been used for a while. I bought a new strap for that. At first the sensor was not connecting to anything (phone, watch) but then I saw a discussion on H10 issues where someone suggested putting a small piece of cardboard under the battery (clearly the battery was not touching the connectors). After this connection worked perfectly. Also tested one workout with H10 & Suunto Vertical. Connection worked perfectly throughout the whole session. It would still be good to have also the Suunto sensor working since I need that for workouts where I can’t use a watch.

I have now some more realistic numbers. I did a reset last week on Monday and then charged it up to 100%. Lowest setting for the screen, always connected to the mobile and some 4 hours activity with Stryd Pod and Polar H10 Some notifications, always on HR & O2 sensor, sleep tracking and the usual stuff. Sleep mode from 10pm to 6am. Today now, after exact 9 days I still have 37% battery life. That’s very OK for me as this will result in 14 days with activity and nearly all features except always on display. I had a Fenix 8 47mm before and the latest firmware there gave me some 9-10 days estimation after charging, but in real life with activities it dropped to about 7-8 days If now some of the already posted bugs (mainly the BT issue with powermeters on stopping, Wahoo Kickr Speed is not shown/recorded, sometimes HR lock and drops with wrist sensor) are fixed, I am VERY happy

@thailon I made one for my race. Haven’t tried it, but could fit for Vertical as well: https://www.thingiverse.com/thing:7108194

@milburnb said: just trying to find a strap that fits As I said above, looks like the original strap for your watch is: SS013706000

@vinc14 said: so where to put the watch? Garmin suggest putting it in your swimming cap. And stating on a footnote that the wrist based function won’t work in that case…

@domucki 1- no need to start an actitivy, but you have to be on the start screen, I’m doing dual recording with my watch and HH just because I want those Suunto badges

@larrybbaker Thank you a lot!

@Squirrel Thanks a lot for the clarification! That actually makes much more sense now. I’ll record my CTL, ATL, and TSB values for the next 2–3 days and compare them to see if the numbers match yesterday’s CTL − ATL. Thanks again!

@pavel.samokha Hmmm… on iOS i can’t select that. It is not possible to say: strava:yes, Facebook:no, WhatsApp:yes, and so on. That is not supporteted for the Suunto App. (iOS Info in Settings/Messages) Correct me if i am wrong.
