Circuit Lap Timing and Delta Analysis
QRacing turns compatible Qstarz GT GPS recordings into lap-by-lap circuit analysis. Drivers can time sessions, review plotted performance charts, and compare lap, sector, and split deltas to see where pace was gained or lost. Automatic detection for supported circuits reduces setup work when a nearby track is available during repeated track-day runs.
The comparison workflow is useful after practice, qualifying, or track-day runs because it keeps multiple timing layers together instead of reducing a session to one best-lap number. Replaying the recorded data lets users study consistency across laps, recognize slower sectors, and carry specific improvement goals into the next outing.
Flexible Drag Race Measurement Modes
Drag-racing tools cover speed, distance, quarter-mile, and 0-speed-0 measurements, giving users several ways to define an acceleration or braking test. Common targets can include 0-100 km/h, 100-200 km/h, 100-0 km/h, 100 meters, or 400 meters, while custom criteria support a more specific vehicle setup or test plan.
These modes make QRacing practical for repeated performance checks rather than a single fixed benchmark. A driver can compare similar runs under the same measurement rule, examine changes after adjustments, and keep circuit timing separate from straight-line testing. That flexibility suits cars, motorcycles, and controlled motorsport sessions using compatible Qstarz hardware.
Video Recording with GPS Data Overlays
QRacing can record phone video while pairing the footage with logged racing data, creating a visual replay that carries timing and route information over the drive. This gives users a more readable way to connect what happened on track with lap times, speed changes, and the recorded line instead of reviewing numbers by themselves.
Saved sessions can be listed and played back later, so drivers can revisit a run without rebuilding the analysis each time. Video sharing also helps communicate a session to teammates or friends, while the data overlay preserves useful context. Because session backups exclude video, footage should be managed separately when it needs to be kept long term.
Track History, Profiles, and Session Management
QRacing keeps repeated use organized through historical session lists, track rankings, racer profiles, and garage management. These tools help separate drivers or vehicles, return to older records, and follow performance over time. Session data can also be exported in CSV format for users who want to review figures in a spreadsheet or maintain an external archive.
Version 3.3.4 adds backup and restore access through User Settings, providing another way to protect recorded session data when changing phones or maintaining a longer history. Backups do not include videos, but they can preserve the records that support comparisons, profile organization, and future analysis across circuit and drag-racing activities.
