@Christoph-Van-Laethem said in Styd update Sync Vertical 2: linking the Stryd is not always possible: it keeps asking for the crank length OMG, this is still not resolved? Good thing I abandoned the idea of getting Stryd.

@SamuelP Are you crazy??! Never ask for firmware updates! Some people take that very badly…

I am using vertical for cycling, and waiting for suunto bike computer…

Hi everyone, I am experiencing similar issues on my Suunto Race since a few weeks. The heart rate is often too low (so far only observed while running), sometimes there are sudden jumps after a while. When using an external heart rate sensor, it works. What you should do if you experience the same: Contact Suunto Support! Only then they will now about it. I did this and they told me they are currently not aware of such an issue, but will investigate. They also asked me to upload my log files via the mobile app and will check them. The more people report this, the higher chance that this gets fixed soon. You can find their support chat directly on www.suunto.com by clicking on ‘Support’ at the top and then using the chat on the bottom right.

@reijervanrijsbergen I’m having the exact same issue. It’s further complicated by GNSS jamming. I’ve noticed that once the heart rate signal is lost, it doesn’t always recover, even when the watch is worn directly on my wrist rather than over a jacket. Coros HRM + Suunto Race S.

@Nandodiver said in In Backcountry skiing it sucks!!!: @Brad_Olwin 220 minus age that’s the official method largely used for more than 30 years More recently in 2023 some endurance athletes start using the “Nes formula” 220 minus age: 220 - 60 = 160 bpm Nes formula: 211 - (0.64 × 60) = 211 - 38.4 ≈ 173 bpm Most of those formulas are poor, it does not matter how long they have been used. Typically the subjects the formulas are based on are sedentary or do not exercise much. Second, max HR is highly genetically determined and variable. For me the formulas give numbers that would severely negatively impact my training. Max HR should be determined by training if possible. There have been many posts here and I see on Apple forums where individuals are exercising for 60 min or more in Z5.

Suunto please look into this. Give an option to turn off buzz on connect maybe? I’m getting a bunch on my new PP9 and seem to have no reason for them. Supper wasn’t helpful

@ahstreak Bonjour je viens d acquérir une suunto run depuis vendredi dernier les cadrans y sont bien mais pas synchronisables. J ai dialogué hier avec un gars du support suunto il m a répondu que l application mobile avait des problèmes de synchronisation. J espère que cela va être resolu car ça commence mal pour moi avec ce produit . Je m interroge sur la fiabilité de cette application . Je souhaite que tout se passe pour le mieux ensuite car pour l instant je suis déçu du produit.

@nandodiver hi. i have two questions. does Suunto nautic s support 3D dive map sharing like in suunto Ocean? lastly, would you prefer it to the Garmin Descent G2? thanks

@pavel.samokha said in Sports Tracker on Apple Watch: app crashes when taking a break while following a route: I transmitted it to developers Thanks Pavel

@Squirrel Thank you! So I will charge it inside from now on.

Apologies if this isn’t the right topic to be posting this issue but it is certainly pertinent to the use of external HR sensors with the Suunto Run. Putting aside the issues i have had with the Coros armband which i have posted about in that specific topic i have also experienced issues when using a chest strap. The HR graph normally looks absolutely fine as expected but i am usually given a different max heart rate in the run summary. [image: 1772494841112-screenshot_2026-02-22-18-21-23-970_com.stt.android.suunto.jpg] [image: 1772494883386-screenshot_2026-02-22-18-21-44-133_com.stt.android.suunto.jpg] This example is from a run where i chucked in three sprints and as the graph shows my heart rate doesn’t go above 180 which is inline with what i expect for the effort. With a chest strap the Heart rate summary seems to always be different to the graph. What’s odd is when using a chest strap, which works perfectly with my other watches, i get this max heart rate discrepancy and the synced data in Strava will show a mix of the correct max heart rate which is reflected in the Suunto produced graph or it will show what i’m sure is the incorrect max heart figure as produced in the Suunto app summary. There seems to be something going on here with the relationship between watch and external sensors and how the data is all displayed within the app. Is this something seen before on Suunto or unique to how they process the data? My experience with Suunto only extends to the use of the Suunto Run having used Garmin for years.

@paolo-1 Use RunGap, it will upload all Apple Workouts or Strava to Suunto. You will have to pay a small fee and you can find RunGap in the App Store. In the future add SportsTracker app to your iPhone and Apple Watch and connect the Apple Watch. SportsTracker is developed by Suunto and will automatically sync Apple workouts and SportsTracker workouts on the Apple Watch to the Suunto app. SportsTracker and Suunto app share the same database.

More than two years after the latest post (which wasn’t answered) I just had the same issue. Bought the S9PP end of last years as it was in sale and I thought meanwhile all SW Bugs should have been fixed. Send logs to Suunto. How to rely in that watch for things like Everesting? During the last three months three soft-resets were necessary. My son bought it about four weeks ago and in last week he deserted it four times. As said a few posts above: this is annoying

I love this Watchface! Clean & Simple SUUNTO. It’s not just a watch, it’s an attitude. [image: 1772452582162-img_4369.jpeg]

@Philip A €100 watch can display many metrics, but that doesn’t mean the data quality is comparable. More numbers do not necessarily mean better measurement. We don’t know exactly which computational models Suunto uses on the Vertical 1. Sleep and HRV algorithms are strongly tied to the hardware, especially to the OHR sensor and signal quality. The Vertical 2 uses different hardware and a different optical heart rate sensor. It is plausible that any algorithmic evolutions are designed around the newer sensor and are not backward compatible with the Vertical 1. For this reason, realistically, it is difficult to expect major new implementations on the V1. Future developments are more likely to focus on the newer hardware platform. The price of the device is not the decisive factor. The hardware architecture is. EDIT: From the photos, the Suunto Ocean sensor appears to be the same as the one in the Vertical 1, and the Ocean does report deep, REM, and light sleep stages. So, in theory, the Vertical could inherit those features. That said, I may be oversimplifying. Even if the hardware looks similar, firmware architecture, signal processing, and model calibration can differ significantly between devices.

@sky-runner oh you are right! sorry, my bad, I thought there was an app for segments Hope you get some answers!
