Momentum Score could be Polar’s next training metric

Polar may be working on another way to tell you how your training is going. The Finnish company has filed a European trademark for something called Momentum Score, suggesting a potential new fitness metric.

The trademark application was submitted on October 16, 2026, under number 019436943. It is currently under examination by the European Union Intellectual Property Office.

The filing covers software for collecting and analysing biometric data, physiological signals and exercise parameters. It also includes exercise coaching, training instructions and applications related to fitness and wellbeing. Which is pretty broad.

What could Momentum Score actually measure?

Your guess is as good as ours at this stage. Momentum Score could be about keeping active day after day, tracking whether your fitness is improving, or simply showing how well you’re sticking to your exercise routine.

It might also have more to do with everyday movement than serious training. With Polar now selling the screenless Loop, a score that encourages people to move more, sit less and build better habits wouldn’t be a huge surprise.

Then again, perhaps Polar is thinking of something broader. Momentum Score could combine sleep, activity and recovery data to give you an idea of whether things are generally heading in the right direction. Or it might be a motivational feature that rewards consistency rather than pushing people to exercise harder.

There are quite a few directions Polar could take this. The problem is that the trademark gives us absolutely nothing about how the score would work or what it would actually measure. So, for now, we’re left guessing.

Another piece of Polar’s software plans

Polar has several other developments in the pipeline.

We previously discovered references to the Polar H12 inside the Polar Flow app. Subsequent app discoveries revealed additional connectivity details for the upcoming chest strap, including support for broadcasting heart rate to four Bluetooth devices simultaneously.

Polar also filed a European trademark for the H12 name on October 12, just four days before Momentum Score. That doesn’t mean the two are connected, and there’s currently no evidence suggesting the new metric would be exclusive to the sensor.

Adding another score would only make sense if it told users something they weren’t already getting from existing metrics. Whether Polar has found a useful new angle remains to be seen.
