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!

Brilliant overlay system for videos

Superb app ! Once you upload your videos it finds your lap times, best lap, best sector, sector gains and losses and it’s all in the overlay! And it’s simple to use. Plus the customer service is absolutely superb. They are always happy to help and give you great advice and figure Any problems out straight away. Makes the track days and race days even more exciting seeing the footage it’s a must download app for any motor heads out there, I use it for motorbikes but I’m sure it can be used for car trackdays as well

Absolutely Genius

This app is pure Genius! Namely, the Genius Tips, it’s the number one feature that sold it for me. It’s like having your own personal performance coach in your pocket, it’s better than your usual ‘Compare’ mode that you see in every other app, as you still have to figure out where your Gains & Losses are, boring! And above all, it’s easy to use.

Highly recommended, keep up the good work!

Developer Response ,

Excellent, we really appreciate all feedback.
