HR issues after update 2.50.28 – Great hardware, failing software?
-
Hi Everyone (and hopefully Suunto staff),
I’m posting this to bring attention to a critical issue I’ve encountered. For context, I have been using activity trackers for nearly 15 years and recently switched to Suunto after using various other smartwatches.Unfortunately, after updating to the newest OS (2.50.28), the heart rate tracking during workouts has become unreliable. As you can see in the attached screenshot, my pace remains constant, yet my HR spikes aggressively for no apparent reason.
Coming from a sales and marketing background, this reminds me of the “Blackberry” era—great hardware let down by inconsistent software. Suunto’s build quality is incredible, but the software feels unstable. I’ve only been with this brand for a month, but I am already considering switching back because of these issues. If a new user like me is frustrated enough to leave, I imagine many others feel the same.
Please take this note seriously. Without urgent improvements to the software department, I fear for the brand’s longevity. -
@louispar what kind of workout has this been? Has it been better (for these workouts) with the older software (pre 2.50)?

@louispar If you are serious about tracking HR during training I would use an HR belt. For me I do not trust any manufacturers OHR. Apple for me is the best but not good enough to rely on.

@2b2bff morning walk. And yes! It was better! Actually you can just refer to the graph that I have attached it’ll explain the inconsistency.

@Brad_Olwin I agree, but manufacturers still need to meet a baseline level of performance. Otherwise, we’re essentially paying for junk, don’t you think?"

For me the older version was often a random number generator. Therefore you need a “before” and an “after”

For serious tracking, I do this myself. But not for a walk, a hike or a bicycle commute…
