Laptimer
Free Laptimer For Track Days
LapsHub is a free GPS laptimer. Mount your phone, pick Phone GPS, and time laps at catalog tracks. Your crew can follow live from the paddock.
Start the laptimer in three steps
Mount and pick Phone GPS
Suction-mount the phone high with a sky view. Skip the cup holder. Start the session in the paddock and wait for a GPS lock.
Drive the catalog track
Keep the laptimer running through the session. Follow organizer rules, including HPDE mode when timed display is not allowed.
How the LapsHub laptimer works
Open Drive, pick Phone GPS, and roll. Curated finish lines time laps immediately. Other catalog tracks can learn a finish line when you return to start.
Your crew follows live lap times while you drive. After you park, open history, compare, or coaching notes. Phone sessions stay in live-event views and your history, not public leaderboards.
Phone GPS laptimer
Time laps on catalog tracks with the phone you already carry. Free on iPhone and Android.
Live to your crew
Lap times and session progress stream to the paddock while you drive. Built for groups, not only solo logging.
Debrief after you park
Compare, coaching notes, and map marks stay in the same app as the laptimer.
Optional sharper GPS
Pair a RaceBox Mini, Mini S, or Micro for 25 Hz, or a Dragy Pro over BLE, without leaving LapsHub.
What a laptimer does
A laptimer, also written lap timer, records how long each circuit lap takes. A GPS laptimer detects the finish line from your position, so you do not need a trackside beacon to start.
LapsHub is a track day laptimer first: phone GPS timing, live crew views, and a debrief after you park. Pair a RaceBox or Dragy later when you want sharper GPS.
Laptimer vs Harry's LapTimer
Drivers who search laptimer often find Harry's LapTimer first. LapsHub is the free phone-first alternative: GPS timing, live crew, and coaching in one track day app.
