Track Day is an all-in-one tool for measuring your vehicles performance at the track. Using track day you can measure your vehicles acceleration times, record lap times automatically, and display real time cornering, acceleration and braking g-force information.

With Track Day installed on your iPhone or iPod Touch, the only other things you will need for a day at the track is your car and your helmet!

Features highlights:
- Measurements and timings for your car's power and acceleration.

- Timed runs for a range of imperial and metric distances - 60 feet, quarter mile, 400 m, 1 km and many more.

- Timed runs for a a range of imperial and metric speeds. 0-40 mph, 0-60 mph, 0-60 km/h, 0-100 km/h and more!

- Ridiculously configureable testing. Choose only the measurements you care about. Want to measure both 60 ft and 1/4 mile, as well as 100 m and 400 m? No problems.

- Real-time graphical display of cornering, acceleration and braking g-forces. With day and night themes!

- Automatic lap timer utilizing Location Services (GPS) to detect completed laps (iPhone 3G required, sorry original iPhone/iPod Touch users!).

- All units of measurement are available in imperial or metric. Power can be displayed in kilowatts, horsepower or even metric horsepower (PS) for the JDM fanboys.

Customer Reviews

accurate but finicky

I bought this to use as a lap timer. I used it for two days at a PCA Driver's Ed at Barber Motorsports. The start point cannot be saved, and it cannot be made while moving. Moreover, on this track, which doubles back on itself, it would think I was at the start point after just a third of a lap. I resolved this by setting the start point at a point at one far end of the track. Since this could not be saved, i had to redo this process before each run. Once I figured this out, the lap timer worked well, accurately logging lap times. It is VERY helpful to look at a time while in the car- instant feedback as to what IS fast, vs. what FEELS fast. To get five stars, it's gps position accuracy needs to be much tighter, and it needs to save start points. Even so, it is by far the cheapest way to time laps while driving. If it would record g-forces over several laps and let you save or export the data for later review, it could replace data loggers that are very costly. As for the other functions, it seems about the same as dynolicious. Since they are about the same price, the inclusion of a lap timer makes this a no-brainer in comparison.

Not quite there yet

Problems with this program for $12:
1. No ability to save, store, recall data! The whole point of this software is to monitor data for interpretation of driving improvement. This should clearly be a function of a program at this price point.
2. The lap timer function needs the ability to set and remember/store a start point. It also lacks acuracy at high speeds. Also a listing of the difference between lap times would be nice.
Make some updates, and I'll revise this review. It sucked having to use a manual lap timer because of these faults.

Almost there . . .

2 suggestions for that 5th star:
1) The lap timer should lock onto GPS when you select the lap timer function, and actually start timer when you hit Begin.
2) Some way to store the cornering/braking/etc. data for later review.
