Most fitness-focused wearables try to check off many different tasks, from monitoring heart rates to counting steps to tracking sleep and more, but the Polar OH1 opts to master one function rather than doing decently at several. The newly released device measures heart rate and heart rate alone, using optical technology that provides the most accurate data possible.
Part of the benefit of such a specified product is that it can be impressively accurate while still saving consumers money. The Polar OH1 can save up to 200 hours of heart rate data from workouts, but it costs less that half the price of competing wearables that come with extra features. Plus, the device can couple with other Polar products through the company's app, so it can still contribute to a complete workout analysis.
