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!) https://github.com/FlorianMuellerklein/OpensourceGPSDevice4AutoXDatalogger 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.

Bugs and requests
nRF Connect for Mobile
Reported bugs
4 issues- Can't read data from Bluetooth device
- Tries to ask for Bluetooth connection when Bluetooth is off. Asks to connect to devices when Bluetooth is off. Who knows what this app is doing in the background without permission?! What ever it is , it ain't good
- Tapping "tabs" doesn't work (nothing changes in the UI). To get some response from tapping UI controls typically requires (a) launching nRF Connect, (b) switching to another app, (c) switching back to nRF Connect. I've tried uninstalling and re-downloading. Same result. This used to be the bee's knees of BLE tools but it's only worth 1 star at the moment (v2.7.11).
- Cant go past the initial announcement. The app is unresponsive to the taps.
