## What is AutoX Data Logger?

Data logger for collecting and analyzing run data for autocross. Map the course, record your runs, then analyze your performance! The app is designed to be quick to use to quickly analyze data between runs and find time during the event. 

* Map the course, including the cones! 
* Record your runs with video (GoPro or internal camera), GPS, ODB2, and accelerometer data
* Analyze your runs with GPS traces, video, speed vs distance plots, and g-force plots
* Automatically start and stop recording for hands free data logging
* Export your data (csv, json, and VBO)
* Import runs from others
* iCloud data sync

The data collection is based on GPS/GNSS data and is compatible with various devices. Some of which connect directly to the app for the highest quality data collection. The solutions which provide the best quality (25hz or 10hz) data are:

* RaceBox Mini
* RaceBox Mini S
* RaceBox Micro 
* Dragy Pro
* Dragy Lite
* XGPS160
* Opensource DIY GPS modules (build for under $50!)

Alternatively, the app is compatible with any GPS device which pairs to the iOS settings. 

Video recording
* GoPro 5/6/7/8/9/10/11/12/13
* Internal iPhone Camera

Vehicle Data
* BLE ELM327 readers
* Veepeak ODBCheck Plus is the most tested and recommended device
* Custom sensors that broadcast byte packets on a BLE characteristics. Make whatever you want and broadcast it in a compatible way. 

Additionally, when using the internal iPhone GPS the app contains an optional sensor fusion algorithm to interpolate between the 1hz GPS updates that the internal sensor provides. Typically 1hz is too slow for motorsports applications but this may provide usable data with no additional hardware required.

## Key features

- Course mapping with cone placement
- Video, GPS, and accelerometer run recording
- GPS traces and speed/g-force plots
- Automatic start/stop recording
- Data export and import
- Optional sensor fusion for internal GPS

### 5/5 — A really good start!

*2025-07-08*

I box a Race box mini. The app RaceBox has is terrible. It’s like they’ve never done Autocross before. This app is leagues better just in the fact that you can set individual start/Fin points without needing to be driving at 3+mph! 

Suggestion for development: add G forces to analytics so when comparing two runs you can see which run had better G’s at certain corners. 

As well, the addition of a live delta comparison would be great.  (green light your going faster, red light you’re going slower)

### 5/5 — Excellent mapping a course. Makes this the best Autocross app.

*2025-06-09*

Finally got time off work to autocross. Got to use the app. I had an issue where I had not set the start cones properly so I had to manually start the timing.  I would just hit the record runs option as I started. Love the app the mapping of the cones is awesome.  I had to make the course today so I have put the cone layout into GoogleEarth so we can print out a course map for future use. 
The auto start feature makes this app super easy to use. 
Loving the app.

### 5/5 — The best Autox and track day app

*2025-05-11*

I use this every time I’m at the track. The dev is great and listens to feature requests. The app is great as is but I’m excited to see where it goes!

## Version history (last 5 releases)

### 1.36 — 2026-08-27

New Sensors!
* Support for Dragy Pro and Dragy Lite
* Support for custom sensors. Create anything you want, send byte packets, parse them in the app, then visualize the data. 

Changes
* VBO file creation now lets you choose which runs to use
* Max video export length is now 4 minutes
* Sensor info now reports GPS Hz, GPS battery, GoPro battery

### 1.35 — 2026-08-12

New
* Support for XGPS160 @ 10hz!
* Rudimentary circuit mode for the occasional track day.
* Landscape mode for chart analysis, allows for three data streams to be shown at once alongside the map.
* Finish lines are now required to be directional. Helps prevent false finish line crossings on tight courses. 

Improvements
* GoPro download queue so videos aren't lost if a new run starts before the previous one finished downloading.
* Improvements to internal IMU sensor accuracy
* Reduced CPU load for sensor fusion
* Some UI clean up
* Increased video export length to 150 seconds 
* Selectable data channels in advanced video mode

### 1.34 — 2026-06-25

This update is all about giving you more access and flexibility with the data. Support for iCloud syncing and VBO file exporting!

New
* iCloud syncing across devices. Record data on an iPhone and analyze the data on a larger screen with your iPad.
* VBO file exporting. Allowing you to analyze data on a desktop with the CircuitTools app or create custom video overlays with RaceRender. Exported VBO file contains instructions on how to export/rename videos manually. 

Changes
* Updates to the sensor fusion algorithm for better reliability .
* Adds some patience for speed based auto stopping.
* Decreased max video export length from 2 minutes to 90 seconds (prevents older iPhones from crashing on long video exports).
* Removes the setting flag for start/finish parsing. The app will now always attempt to parse runs if start/finish lines are present. It will save both parsed and unparsed data by default. 

Fixes
* Prevent ELM327 packet drops from interrupting entire data stream
* Video sync bug

### 1.33 — 2026-05-13

New
* Advanced video mode added. In the "Videos" tab turning phone into landscape orientation will enable this mode
