Race Buddy vs The Bracket Racer

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 iPhone’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.

Know your number before you stage. The Bracket Racer predicts your car's next elapsed time from live track weather, then learns your car from every run you save — so your suggested dial-in gets sharper every meeting. Built for bracket racers, with live weather for major strips including Willowbank, Sydney Dragway, Perth Motorplex, The Bend, Warwick, Springmount, Calder Park, South Coast, Mildura and Hidden Valley — plus manual weather entry for anywhere else. HOW IT WORKS Save one baseline run — your ET, 60ft, MPH and the density altitude it was set in. From there the app corrects your prediction for the air you're actually racing in: density altitude, humidity, barometric pressure and headwind or tailwind down your strip's true heading. IT LEARNS YOUR CAR Every run you save teaches the predictor. It weighs runs from the same track and similar air more heavily, ignores the odd bad pass instead of averaging it in, and shows you exactly how much it has learned. Watch the accuracy build with your run history. MADE FOR RACE DAY - Live suggested dial-in, updating as the air changes - Density altitude trend — see the air improving or fading between rounds - Head/tailwind effect calculated for your track's actual direction - Full weather board: DA, correction factors, dew point, wet bulb, water grains, vapor pressure and more - Optional 60ft correction for track conditions - Run log organised by track and race day, with prediction-vs-actual accuracy at a glance - Supports quarter-mile classes and Junior Dragster eighth-mile No ads. No tracking. Your run data belongs to you, and you can export or delete it any time. From club brackets to championship rounds — spend less time guessing and more time cutting lights.
