About this app
Time your laps. Measure acceleration. See where you can improve. RaceBuddy brings lap timing, drag results, performance analysis and video overlays together for closed-course driving.
LAP TIMING AND ANALYSIS
• Record lap times and sector splits on circuits worldwide.
• Follow live delta timing and compare laps to find where time is gained or lost.
• Review your racing line, speed and session history.
DRAG AND ACCELERATION
• Measure 0–60 mph, 0–100 km/h, quarter-mile and rolling acceleration.
• Review run graphs, slope and conditions alongside your results.
• Compare runs and follow DIFF time or predicted quarter-mile ET with PRO and compatible external GPS.
VIDEO WITH YOUR DATA
• Record driving video and export it with synchronized telemetry.
• Show speed, lap times, G-forces and track position.
• PRO adds custom layouts, portrait output and export up to 4K.
POWER AND ENGINE DATA
• Estimate power and torque from a GPS run with PRO. Results depend on measurement conditions and vehicle settings.
• Record supported OBD-II channels, such as RPM and throttle, with PRO and a compatible adapter.
• Keep vehicle profiles and compare your performance over time.
CHOOSE YOUR GPS SOURCE
RaceBuddy ONE, Dragy, Dragy Pro, RaceBox Mini, Mini S, Micro, RaceBox.cc and RaceHF are supported. An external GPS receiver is recommended for greater timing precision.
Phone Mode is also available using your phone’s GPS and sensors. Its timing precision is limited. DIFF time and predicted ET require compatible external GPS.
FREE AND PRO
Free includes Phone Mode, connection to RaceBuddy ONE, lap and drag timing, session history, VBO export and 1080p landscape video overlay export, subject to the GPS-source limitations above.
PRO adds third-party GPS connections, run and lap comparison, Power & Torque, OBD telemetry, advanced video layouts and export options, and custom track creation. A compatible GPS receiver or OBD adapter is required for the corresponding hardware features.
PRO is available as a monthly or yearly subscription, or a one-time Lifetime purchase. See the app for current offers and terms.
For closed-course use only: circuits, drag strips and autocross courses. Not for street racing.
