TermWhat it means
ArrivalWhen you reach the destination, on the destination’s clock. Assumes you drive without stopping.
BriefingA short spoken summary of the drive, stretch by stretch. See The briefing.
CalmThe lowest rating: nothing in the forecast should affect the drive.
CautionThe middle rating: the weather slows you down — a wet road, or less far to see.
Clock changeA point on the drive where the local time changes: a time zone crossed, or summer time starting or ending.
ConditionsThe eight readings for a section: feels like, wind, gusting, chance of precipitation, precipitation, visibility, humidity and cloud cover.
DawnThe twilight before sunrise, from when the sun is 6° below the horizon.
DepartureWhen you leave, set in your device’s time zone. Every section is forecast from it.
DriveA start, a destination and a departure time, with the forecast along the road between them.
DrivesThe tab listing your saved drives. They are kept with your account and appear on every device where you sign in.
DuskThe twilight after sunset, until the sun is 6° below the horizon.
Elapsed timeTime counted from your departure, such as +02:35, instead of the clock.
ExploreThe map tab, where the plan form sits over the map. Called MAP on the web.
ExtremeThe highest rating: do not drive into this.
Founding membershipA record of when your account joined during the free period. Future pricing and early-user benefits are undecided.
HazardThe second-highest rating: the weather genuinely affects the drive.
LEARNThe sheet that explains a reading or a rating, opened by tapping it in a section.
Local timeThe time on the clock where a section is, with its zone, such as 14:05 MDT.
Low-light drivingTime the drive spends in night, dawn and dusk together, in Trip details.
MarkThe small rating beside a single reading when it crosses a threshold. It is not the section’s rating.
MildThe second-lowest rating: worth knowing, but it does not change the drive.
RadarRain and snow observed over the last hour, shown on the map. Not the forecast.
Saved on this deviceA change the device has kept but not yet sent to your account. It goes when the device is online.
SectionA numbered stretch of road with weather that reads alike, forecast for when you reach it. See Sections.
SeverityHow much a section’s weather affects the drive, in five ratings from Calm to Extreme.
StripThe bar at the top of the timeline: every section in order, in its rating’s colour.
StretchIn the briefing, neighbouring road with the same kind of weather. On the map, sections grouped when zoomed out.
TimelineThe list of the drive from departure to arrival: sections, light changes and clock changes.
Trip detailsThe summary of a drive: distance, driving time, arrival and low-light driving.
WorstThe rating of a drive’s worst section, which is the drive’s own rating.
