Version History New:

- Caution and pit laps are hidden and never counted: your 15-lap feature reads laps 1–15, on the session page, in Analyze and in corner splits. Switch them on to see them in yellow, and use the slider to set what counts as a caution. Works for RaceBox runs too.
- A cleaner session page that's easy to read in dark mode.
- Corner splits: export every lap's splits and speeds as a spreadsheet. Optimal is gone. 2.35.0 17h ago Fixes:

- Importing from a GoPro now checks that the GPS got a good lock before copying anything, so a recording with no usable GPS is caught on the phone instead of uploading with no laps.
- Opening a GoPro session that was deleted on another phone or the website now says it was deleted, instead of "Failed to load session". The trash can clears it from this phone.
- GoPro imports made from this version on drop off the list by themselves once their session is deleted elsewhere. 2.33.4 5d ago Corner splits
• Tap the track to place lines at corner entry, mid corner and exit. Every lap gets sector times, your best sectors are highlighted, and you see your optimal lap and your speed at each line.
• Lines are saved for the track, so every run there, RaceBox or GoPro, is split the same way. Road courses get numbered turns.

Laps at any track
• RaceBox runs get laps even at a track that's not on our list, in either direction. Make a new track right where you raced.
• A run with no laps (a drive, a test pass) shows a map, your speed and each run's time, distance and top speed.

GoPro sessions work like RaceBox runs
• Set the track, add corner splits, driver, run type, race event, setup, notes and weather, and export. Laps are timed from the track's start/finish line.
• Your runs are grouped by night at the track, and one filter works on both RaceBox and GoPro.
• Delete a GoPro session from its own page.

Fixes
• The app only offers to erase your RaceBox once everything on it is downloaded and saved.
• GoPro videos stay with their sessions after an update, and sessions are dated correctly even when the GPS was slow to lock.
• Clear help when the GoPro won't connect over Bluetooth. 2.31.1 6d ago Corner splits
• Tap the track to drop split lines at corner entry, mid corner and exit. They're saved for that track, so every run there, RaceBox or GoPro, is split the same way.
• See every lap's sector times with your best in each sector picked out, your optimal lap, and your speed at each line.
• Find it under your lap times, or tap the flag on the analyze screen.

GoPro
• Delete any GoPro session right from your runs: tap ⋯ and choose Delete. The recording stays on your camera if you want to import it again.
• Your onboard video now stays with its session when you update the app. Videos an earlier update lost track of come back on their own, as long as they're still on your phone.
• Sessions are dated correctly, even when the camera's GPS took a while to lock on.
• A recording with no laps tells you why in plain words.

Fixes
• The RaceBox no longer shows as connected while the app is talking to your GoPro.
• Disconnecting a RaceBox that has already dropped off no longer fails. 2.27.6 Oct 7 mport from GoPro
• Copy your laps straight off a GoPro with GPS. No SD card, no computer. DST times every lap and finds your track.
• Watch your onboard video right beside the telemetry. Play a lap and the map, speed and gap follow along.
• Slow it to ½× or ¼×, or jump to the same spot on your other lap to see exactly where the time went.
• The video stays on your phone. Remove it anytime to free up space.
Plus fixes and faster, smoother loading. 2.27.5 Sep 29 What's new:

- Import from GoPro: copy lap data straight off your GoPro (GPS on) from the Data Logger. The app uploads it on its own once you have signal, even on the drive home.
- GoPro sessions open in the same lap overview and analysis as your RaceBox runs.
- A cleaner Data Logger: RaceBox status and Record, Sync and Live data in one card; runs grouped by race night with your finish in its own column.
- Past runs stay on screen with Bluetooth off. 2.26.0 Sep 24 Lap analysis, rebuilt
• Your two best laps are compared automatically when you open a run
• New Time Lost chart shows where on the track each lap gains or gives up time
• Speed traces for both laps on the same distance axis
• Change either lap or swap them with a tap, right on screen
• Lap times now match your lap table everywhere

Run details
• Tag each run with driver, run type (heat, feature, qualifying and more), finish and result
• Link runs to race events, or create an event from a run
• Filter your run list by driver or run type
• Share or export a run straight from its overview

Choose your track
• Wrong or missing track? Tap the track name to pick the right one
• When the track has a start/finish line, your laps are re-timed from it

Setup photos
• Add up to 6 photos to any setup
• Photos stay with the setup they belong to, and deleting one always asks first

Cleaner, easier to read
• Redesigned menu
• Simpler setup sheet with clearer fields
• Dark mode fixes across the app, and the app now follows your phone's dark mode from launch
• Plus many smaller fixes 2.25.0 Sep 18 Bug fixes 2.24.4 Sep 12 RaceBox data logger fixes:

- The "Uploading Data" card no longer gets stuck on screen or shows an invalid percentage after reopening the app.
- Recordings the server can't accept stay safely on your phone and are retried on the next sync instead of retrying forever.
- Upload progress shows the real total, and the analysis step reports its status reliably. 2.24.3 Sep 4 New AI bug fixes! 2.24.2 Aug 31 Pocket Crew Chief just got a big upgrade:

- Share a saved setup with the Crew Chief and ask questions about your actual car. Tap the paperclip in the chat to pick one.
