## What is Lapster?

GPS lap timer for cars, motorcycles and karts — on any circuit, with or without a RaceBox.

Lapster turns your RaceBox into a complete lap timer and telemetry system. And if you don't own one yet, your iPhone can time your laps too.

RACEBOX — ALL THREE MODELS
RaceBox Mini S, RaceBox Micro and RaceBox Pro. Connect over Bluetooth or Wi-Fi, pull the sessions stored on the device, and every lap is timed, mapped and saved automatically.

NO RACEBOX? USE YOUR PHONE
Start a session with your iPhone's GPS and get real lap times on any circuit. Live map, predictive delta, lean angle, and a separate 0-100 acceleration mode with its own personal bests.

EVERY LAP, IN DETAIL
• Replay any lap on the map at 1x, 3x or 5x
• Speed, position and time for every corner
• Put your lap next to a friend's and see where the time went
• Sector splits, top speed, G-forces and lean angle

FOLLOW YOUR CREW
Home is a feed of the latest rides of the riders you follow, with their personal bests, comments and reactions. One search field finds riders, tracks, sessions and teams.

TRACKS
Official circuits with verified records, plus tracks you build yourself — drop the start/finish line and sectors straight onto the map. Every track keeps a leaderboard of the drivers and riders on it. Records and leaderboards are kept separately for cars, motorcycles and karts.

TRACK DAYS
Find track days, book your spot, and read reviews from drivers and riders who were actually there — with their photos and lap times attached.

SHARE IT
Send a lap or a whole session with a link, post a story, or export a poster for Instagram. Your profile keeps every stat and badge you have earned.

MESSAGES
Direct and group chats with other drivers and riders, including voice messages.

ALSO INSIDE
• Import your existing rides from the RaceBox app (CSV)
• Weather recorded automatically for every session
• Your garage: cars and bikes, with photos
• Available in 14 languages
• Lap times to the millisecond
• Import rides from AiM loggers (.xrk, .xrz) and Race Studio CSV

Free to use. Optional donations if you want to support development.

## Version history (last 5 releases)

### 1.5.0 — 2026-11-05

• Following feed. Home now shows the latest rides of the riders you follow and your own, day by day, with every personal best on its own card.
• Search everything. Riders, tracks, sessions and teams from one field: tap the magnifier, pull Home down a little, or press ⌘F.
• New track screen. Records, the riders leaderboard and your own sessions on one page.
• Vehicle classes. Records and rankings are kept separately for cars, motorcycles and karts.
• Devices tab. Add a RaceBox or start the phone tracker from the second tab. A borrowed tracker shows whose it is.
• Lap sectors. Sector times in the lap summary and the lap list, and live while you ride.
• Milliseconds. Every lap time now shows three digits after the point.
• Sort and filter. Sort sessions by fastest lap, filter them by track and search your whole history.
• AiM import. Open rides from AiM loggers (.xrk, .xrz) and Race Studio CSV exports.
• Drives. A ride that never closes a lap is kept as a drive, with distance, moving time and speeds.
• Posters. One studio for every poster: day, session, lap, progress and personal best.
• Pit board. The phone tracker shows huge numbers, and colour only where it means something.
• RaceBox Pro. Load Lapster tracks onto the device; nearby tracks are saved for circuits with no signal.
• Apple Watch. A big Lapster complication with your ride status and best lap.
• Notifications. More switches, quiet hours, and reactions grouped into one push.
• Fixes. RaceBox rides no longer split into several sessions, short lap fragments are merged, and lap times are taken at the exact moment you cross the line.

### 1.4.2 — 2026-10-19

• Your profile is a tab. The last tab is your own profile, and Settings open from the gear in its corner.
• Track records. A card on your profile opens your record lap for every track, and a record can be shared to your story as a poster.
• Messages. Reply to a message by swiping it or from its menu, and paste an image into the message box to send it as a photo.
• Track screen. The map runs to the top edge, the record card shows your best beside the record, and a track opens full screen from a session or lap.
• Ride Mandalika and Bangli. Pull down on the track page to open the game.
• What's new. Release notes now live in Settings, with a fire to tap.
• Team pages work like a rider profile, and timing sheets can be searched and filtered.
• Photo viewer. Tap to hide the controls, scrub with the thumbnail strip, and swipe past either end to wrap around.
• Lap screen. A button in the map controls turns it sideways without turning the phone.
• Apple Watch. Start and stop the RaceBox from your wrist, see the live ride, and play chat photos, videos and voice notes.
• Smoother and more responsive: 120 Hz on supported iPhones, and haptics answer saves, sends and syncs.
• Fixes. A connected RaceBox Pro stays in your devices list, Home opens without a spinner, a recording in progress survives a crash, the app no longer crashes when storage is full, and Home is no longer black when signed out.

### 1.4.1 — 2026-10-09

• Added personal PDF timing sheet imports: open a file in Lapster, select your name, and save your results to your profile.
• Expanded the iPad experience with dedicated layouts for corner analysis, lap comparison, teams, notifications, settings, track creation, and stories. Added keyboard shortcuts and trackpad support.

• Added support for start/finish crossing direction when detecting laps.
• Improved iPhone GPS recording, recovery of unfinished rides, and synchronization on unreliable connections.
• Improved RaceBox Pro Wi-Fi connectivity, session downloads, and connection recovery after interrupted transfers.
