Awesome trackday timer

Great performance logger: TDG is more than I expected, it's not just another iPhone Laptimer, there's a lot more to it! There are some genuinely good features that helped me understand my on track metrics - braking/acceleration and improved my riding ability' it's really that good! The recent release added a feature that allows 'File imports' from 3rd Party accessories, since I'm not keen on mounting my iPhone on my bike, I set up the trip recording feature on the Dual XGPS160 (external GPS) after I finish my session, TDG syncs the imported .kml file from the Dual XGPS160 with the track Database, it finds the nearby track and any sector data! I get to see all my laps and sector times, Its a shame I can't upload to the leaderboard, yet! Highly recommended!

The best app ever!

Man I love this app, it's Genius (pardon the pun) I've never really been interested in chasing lap times, you only crash when you do. But these guys are on a mission to unlock the science of going faster, but doing so safety and deep level understanding. The main benefit for me was the GoPro integration ( I have 3 GoPro HERO5 cameras), it's faultless, simple and above all clever! When you add the google maps to the mix and vehicle telemetry, it's GENIUSSSSSSSSSSS!

Awesome app that I use with my GoPro seemlessly. Trackdays wouldn’t be the same without it! Proper geek worthy and gives you more data than you’ll ever need and plenty to impress your mates in the pub!
