JV Chrono LapTimer

JV Chrono is a GPS laptimer, OBD reader, video recording with overlays and analysis system for all types of events related to the motoring world or outdoor sports.

• Laptimer for loop and point-to-point tracks.
• External GPS and OBD II compatible.
• Video recording with overlays.
• Steering wheel and byke lean angle measurement.

Perfect for loop or point-to-point tracks ("LAPTIMER" mode), B roads (“OBD II" mode) and acceleration measurements ("DRAG RACE" mode).

Improve your driving skills during the session. The app shows your current position within the track (very useful when the track is unknown) with the areas where you have gained/lost time or gone faster/slower than the reference lap. Modify the racing line and immediately see if you have improved or not. Improve regularity thanks to the predictive lap time.

Analyze your laps and share your data with your friends. The app includes an advanced analysis tool to improve your driving and compare different laps, including laps from your friends. The app synchronizes automatically and plays the videos recorded during the session to analyze them together with the data. Export data to different formats including Google Earth or CSV to generate video overlays.

Focus on driving and avoid looking at the device’s screen. Lets the app play voice messages with the elapsed or delta time with the reference lap. Introduce notes with any text to be played when crossed to remember braking points or the racing line to follow. Perfect for bikers with a bluetooth headset.

Get the most out of your device's sensors. Measure the steering wheel angle to analyze understeer or oversteer, or get the byke lean angle.

Record video with overlays during the session without postprocessing. The app includes in the video the current speed, acceleration, track position or vehicle data obtained by OBD. Use the "REMOTE" mode to control another device like an action camera, recording from the most impressive point.

Only app that increases safety on track. It includes a proximity alert to detect other app users that are close to you in other to notify that you will overtake or being overtaken. Avoid accidents or lost time behind slower vehicles that haven’t seen you.

Connect a Bluetooth OBD ELM327 device and record vehicle data like rpm, accelerator command or engine temps. It includes a gear shift light and sound indicator and coolant/oil temp alerts. Analyze your heel and toe with the gear ratio parameter. Data is recorded at maximun rate, regardless of GPS rate.
