Suggested tweaks to the UI
Using Kilometres for greater distances - approved
The current UI can increase the cognitive load for users. Using kilometres provides a more recognisable number when dealing with longer distances. For example, saying 2.34 km is easier to comprehend at a glance than 2,342 m
DECISION: Use 2.43 km not 2430 m
Once the user’s distance away from the LoA Destination reaches a certain point, typically anything under a kilometre, the unit of measurement can change to meters, allowing for more precise tracking.
