WHY RACE LOG

A whole session in,
and all you’ve got is “felt okay”?

Drive on feel and progress comes down to luck; you make the same mistake in the same corner, lap after lap, never seeing it. Race Log turns every brake, every line, every throttle input into numbers you can actually read and act on.

ON FEEL

“T3 felt kind of off… I think?”

“The last few corners didn’t flow, but I can’t say where.” “Felt a bit quicker than last time… maybe?” “T3 was awkward again, I’ll sort it next time.”

× Don't know where the time went
× Not sure the brake points are right
× Progress is just guesswork
VS
ON DATA

Exactly how much
each corner costs you

“T11 lost 0.56s, T1 lost 0.48s, T8 lost 0.48s.” Ranked by what matters most, so you claw back the biggest corner first.

T11Turned in early, braked too hard+0.56s
T1Late back to throttle on exit+0.48s
T8Apex off by 0.5 m+0.48s

Race Log turns “felt okay” into
“T11 lost 0.56s, entry speed down 12 km/h.”

DATA + REPLAY · YOUR SESSION, MEASURED AND REWATCHED

Every lap as data you can read —
then replayed against the footage

Race Log turns your session into a full data report — lap times, sectors, corner-by-corner gains and losses. Then two video-replay modes lock that data to your on-track footage, so you see exactly where the time went.

REPORT · THE FULL PICTURE

A complete data report
for every session

Race Log mobile data report: best lap, sector splits, corner-by-corner time loss, deep-analysis modules

Best lap, sector splits, corner-by-corner time loss, friction circle — the whole session as numbers you can act on.

SYNC · THREE VIEWS IN LOCKSTEP

Video + racing line + speed trace,
in sync

Race Log three-view replay: video frame + racing line + speed trace playing together

Watch the footage and see the exact moment you lost time — all three views locked to the frame.

DUAL · SIDE-BY-SIDE VIDEO

Same corner, two laps,
stacked to see the gap

Race Log dual-video replay: same corner best lap vs current lap stacked

See which input separates your best lap from this one — the visual gap beats raw numbers.

The numbers tell you where; the video shows you why.

AUTO-DETECTED · 14 CORNERSRace Log real track top-down: T1-T14 numbering / S/F start-finish / 80km/h chip / 4-color sectors
GPS · THE ALGORITHM FINDS THE CORNERS

No preset maps,
no marking the start line,
the algorithm does the dirty work

No preset mapsThe algorithm reads the racing line and start line straight from GPS data — works at tracks you’ve never run.
No marking the start lineStart/finish is detected automatically and aligned with the track’s timing loop, so lap times match the official clock.
High-precision corner detectionEvery corner is split into entry / apex / exit, so time gains and losses are pinned to the phase, not just the lap.
