Polar has started rolling out Polar OS 5, the next major firmware update for its range of GPS sports watches, bringing a host of usability and training improvements.

The update, arriving on models including the Vantage V3, Vantage M3, Grit X2 / Grit X2 Pro and Ignite 3, introduces features that address both everyday watch use and deeper training metrics.

There’s now a dark map mode for low-light runs, smoother pinch-to-zoom controls, and improved route previews to show the direction of your route before you start.

Mapping remains unsupported on models without onboard maps, like the Ignite 3.

Workout summaries during paused sessions now show expanded data, including distance, heart rate (average and max), speed, and calories burned.

New features, at a glance

Polar OS 5 also adds RPE (Rate of Perceived Exertion) scoring directly on the watch, letting athletes rate their effort on a 0–10 scale post-workout, a feature long popular in Polar Flow.

A seven-day SpO₂ trend graph is also included on compatible watches.

The update also addresses repeated iOS notification bugs, improves 3D speed accuracy for hilly routes, and adds the current time to the charging screen.

Polar is rolling out the new operating system to all eligible watches now. Make sure the wearable is connected to the Flow app.

Once connected, and if an update is available, the app will automatically prompt you.

Keep the watch close to your phone and follow the on-screen instructions. Don’t close the app or let the battery die while the update is in progress.
