History In 1975, there was no accurate way to measure heart rate during training, and the idea of a wireless, portable heart rate monitor was conceived on a cross-country skiing track in Finland. Polar was founded in 1977, and the company filed its first patent for wireless heart rate measurement three years later. Its founder Seppo Säynäjäkangas (1942–2018) was the inventor of the first wireless EKG heart rate monitor.Heart rate monitor In 1978, the company launched its first commercial product, the Tunturi Pulser.

In part due to its own history, and the affiliation with universities and the scientific community, Polar offers a research co-operation programme focused on supporting studies in exercise science.Polar's research co-operation guidelines: http://www.polar.com/en/about_polar/who_we_are/research/research_guidelinesSummary page of Polar research http://www.polar.com/en/about_polar/who_we_are/research
In November 2015, Polar released its first optical wrist-reading heart rate monitor, the A360.
In July 2018, Dutch newspaper De Correspondent revealed that Polar's fitness app shows users on the map, making it possible to find out their real names, profession and home addresses. In a reaction, Polar ended some of the online functionality of sharing routes on the map.

Financial performance and market position
In recent years, Polar Electro has faced substantial financial challenges amid a shifting global market for wearable technology. According to official business filings, the company's revenue for the fiscal year ending in late 2023 was approximately €110 million, marking a decline of about 1.8% from the previous year and a significant reduction from earlier peaks above €170 million in 2020. Despite maintaining substantial turnover, Polar reported a net loss of about €15 million for 2023, with an operating margin remaining negative at around -14.1%. The company experienced similar pressures in previous years, including an operating loss of €31 million and revenue of €112 million in 2022.
The contraction in revenue and profitability has been attributed to multiple factors, including high inventory levels among retailers, increased global competition, particularly from market leaders such as Garmin and other wearable brands, and overall weak consumer sentiment impacting the traditional heart rate monitor and sports watch segment.
While Polar Electro remains one of the few internationally recognized Finnish consumer electronics brands, its market position has become increasingly challenged. Compared to global competitors, the company has seen a notable loss of market share, particularly in North America, and has struggled to regain momentum despite investments in product development and a shift towards licensing its proprietary technology to partners. Nevertheless, the company has continued efforts to maintain market relevance, with management expressing the intention to leverage licensing revenues and further R&D investments to support future growth.
