Polar

Polar Electro Oy (operating as Polar Global) is a Finnish sports and fitness technology company founded in 1977 and headquartered in Kempele, Finland. Polar invented the first wireless wearable heart rate monitor — the Sport Tester PE 2000 in 1982 — and remains one of the longest-standing brands in consumer heart rate sensing, GPS sports watches, and fitness wearables. The Polar device portfolio includes the H10 and H9 chest straps, the Verity Sense and OH1 optical sensors, the Polar 360 and Loop fitness bands, and the Vantage, Grit X, Pacer, Ignite, and Unite watch lines, along with a dedicated equine sensor line. Developers access Polar data through the Polar AccessLink API for consumer Polar Flow data, the Polar TeamPro API for team and player training sessions, and the open-source Polar BLE SDK for iOS and Android applications that stream live sensor data over Bluetooth Low Energy.
