The UDisc Garmin app supports keeping score (strokes only), live updating distance to pin using the GPS in your Garmin device, and viewing tee order + a score summary.
The Connect IQ website has a list of currently compatible devices* - tap the Compatible Devices tab in the link above to see more.
*While the Instinct 2 and Instinct 2s are supported, your experience may be degraded due to low available memory. We do not recommend scoring for more than 4 players or more than 18 holes. These devices have some very strict memory limitations and the UDisc app may become unstable or even crash if the scorecard has more than 4 players or is scoring a layout that is longer than 18 holes, and it may or may not work as well as other devices.
