Polar has initiated the rollout of its latest software update, Polar OS 5, to its current-generation sports watches, marking a significant step towards enhancing user experience. The update is being deployed to five prominent models: the Polar Vantage M3, Vantage V3, Grit X2, Grit X2 Pro, and Ignite 3.
The new firmware does not introduce any groundbreaking sports profiles but instead focuses on ‘quality-of-life’ improvements aimed at refining the daily user interface. Among the most noteworthy changes is the introduction of a system-wide dark mode for maps, providing more comfortable viewing during night runs or low-light navigation.
Key Features of Polar OS 5
The update also brings an improved “Night Mode” that dims the display and maintains a minimalist look when Do Not Disturb is active, preventing blinding flashes when checking the time in the wee hours. This development follows user feedback and demands for a more user-friendly interface.
Refining the Interface
The update introduces several long-requested features that enhance the watch’s functionality:
- Multiple Alarms: Users can now set and manage multiple alarms directly from the watch.
- Charging Clock: The watch displays the current time while connected to its charger, a small yet significant convenience.
- SpO2 Trends: A new on-device graph illustrates blood oxygen saturation history over a seven-day period.
- RPE Grading: After a workout, the watch prompts users to rate their perceived exertion on a 1–10 scale.
On the topic of perceived exertion, Polar highlights that these ratings are integrated into its Flow ecosystem, providing more subjective context to the watch’s data-driven training load recommendations. This integration represents a step forward in personalizing user experience based on individual feedback.
Polar’s Competitive Landscape
The announcement comes as Polar seeks to mature its software offerings, historically excelling in heart rate science but lagging behind competitors like Garmin, Apple, and Google in terms of UI polish. The addition of features like the charging clock and multiple alarms may seem minor, but they significantly enhance the watch’s viability as a 24/7 companion rather than just a training tool.
“Small touches like these make the watch much more viable as a 24/7 companion,” notes a technology analyst familiar with the industry trends.
According to sources, the update is currently being distributed in stages via the Polar Flow mobile app, allowing users to gradually experience these enhancements.
Looking Ahead
Polar OS 5 could well prove to be a pivotal moment for the brand’s software evolution. The move represents a sensible update that aligns with user demands and technological advancements. As the brand continues to bridge the gap with its competitors, further updates are anticipated throughout 2026, promising to bring additional refinements and features.
Meanwhile, users and industry experts alike are hopeful that these updates will continue to enhance the usability and functionality of Polar’s sports watches, making them a more integral part of daily life for fitness enthusiasts and casual users alike.
As the rollout progresses, Polar’s commitment to user-centric design and functionality improvements will be closely watched, potentially setting new standards in the sports watch segment.
