Bends and roadbook
Rallymeter Ultra reads the bends of the stage and calls them out with the right lead time for your speed, rally pace-note style. On screen, the roadbook icon and the list of what’s coming.
Import the stage from Google Maps, GPX or KML and Ultra detects the bends and grades them by severity, from flat to hairpin. 6, 9 or 12-level scale, invertible to match your team’s habit.
Bends close together are grouped into one note, “left 3 plus right 4”, with the distance to the next. Voice in your language, speech rate and callout style configurable.
Lead time is computed in seconds from your real speed, not from a fixed distance. At 40 km/h or 90 km/h the note arrives when it should.
Dangerous bends are repeated closer, at a higher pitch, with haptics. Danger threshold and bonus time are configurable.
Tulip-style bend icon oriented to the driving direction with a colour halo by severity, and a list of upcoming bends. Roadbook crossings appear with their sign, a pop-up warning and a second beep before you reach them.

Simulation mode drives the stage at the speed you choose, calling the bends and showing the roadbook, without leaving home. Perfect for tuning voice settings before the rally.
When bends are present, the early/late bar takes the place of the speedo: green within tolerance, blue when early, red when late. You never lose the average because you were looking at the bend.
Voice bends and the roadbook are also available as a standalone app, Apex Notes, for people who don’t do regularity: motorbike touring, track days, mountain driving. Sold separately from Rallymeter Ultra.
We are preparing the beta for iOS and Android. Drop us a line and we will let you know.
