The Polar Grit X smartwatch receives new features from the Grit X Pro with firmware 2.0.12 update
Polar announced the Grit X 2.0 software update for the Grit X smartwatch in October, but it has taken until now for the company to deliver it. Now called firmware 2.0.12, the update brings several new features and customisation options to the Grit X, which Polar released in April 2020.
Once updated to Grit X 2.0.12, the smartwatch can control music playback and volume from a connected smartphone, regardless of whether you are working out or not. Also, Polar has added 'Running Performance Test', which should help people 'know where [their] running performance is now' and set custom heart rate, speed and power zones. Linked to that, Polar has introduced improved route options, allowing you to switch between shorter and longer routes mid-run.
Additionally, Grit X 2.0.12 enables HR sensor mode, making it possible to use the Grit X as a heart rate sensor with gym equipment. Polar does not provide a list of compatible equipment, but the Grit X can transmit heart rate data via Bluetooth Low Energy. Moreover, the Grit X now supports a customisable quick settings menu. Similarly, you can personalise watch face views. You can download Grit X 2.0.12 through FlowSync and the Flow app. Polar explains all its changes with Grit X 2.0.12 in a blog post.
