iPhone
Time your 0-60, quarter mile and top speed with just your phone. New in 2.0: your full garage, personal bests, and in-depth run analysis.
MEASURE YOUR CAR'S ACCELERATION — WITHOUT EXPENSIVE GPS TRACKERS!
With STAR, anyone can measure how quickly their car accelerates. Time how long your car takes to reach a certain speed, or how long it takes to cover a set distance such as the quarter mile — all using nothing but your phone.
Configure your runs safely at a standstill, and with rolling starts the app automatically detects the moment you pull away and begins measuring for you. You can even run multiple measurements at the same time.
Every result is stored locally on your iPhone so you can revisit it later — no data is ever transmitted to us. Each run comes with analysis tools like graphs, top and average speed, a map of the route you drove, and more.
—— FEATURES AT A GLANCE ——
• YOUR GARAGE: Add every car you drive — complete with a photo and details like make, model, year, drivetrain, power, and weight. STAR tracks each car's runs and records separately.
• STATS & PERSONAL BESTS: See each car's best 0–60, top speed, quarter mile, averages, and run counts at a glance — and watch how every new run stacks up against your personal best.
• UNLIMITED MEASUREMENTS: Want to time the quarter mile and 0–60 in the same run? No problem — configure as many measurements as you like at once, and STAR handles the rest.
• DIFFERENT MEASUREMENT MODES: Speed-based or drag race (distance) — choose the modes that fit the run you want to make.
• ROLLING STARTS: Set everything up safely while stationary and let the app do the work — your measurement begins automatically the instant you start driving.
• IN-DEPTH ANALYSIS: Every run is saved locally and can be explored afterwards with a speed graph, top and average speed, route details, and more.
• ROUTE MAP: The route you drove is saved with each run, so you can revisit it later on a map.
• HISTORY, ORGANIZED: Browse all your runs in the archive and filter by car to find exactly what you're looking for. Delete any run you no longer need.
• LIVE SPEED & GPS INFO: Keep your current and top speed in view throughout every run, and check your live GPS satellite count to confirm a strong signal before you launch.
• DARK MODE: Driving at night? STAR follows your iPhone's appearance settings and includes a dark mode with true blacks — easy on your eyes and your battery.
• PRIVATE BY DESIGN: All of your data stays on your iPhone. Nothing is sent to us.
