Description

Harry's LapTimer is the advanced tool for car enthusiast. It records all types of sensor data provided by your iPhone/iPod/iPad (or external sensors), combines them, and makes them available to optimize your drive. Over time, you will get insights on your car and in your driving, not known before.

LapTimer offers more than 1000 predefined tracks world wide. With its assistants, it is extremely easy to setup - just click your track and drive. It fully automates your lap timing using GPS, and presents the results to all kinds of media.

You are not limited to track driving only. For example, you may define your home and working locations as a 'track', collect statistics on different ways chosen, and analyze / optimize the time used every day.

Want to show your drive to your friends? LapTimer Petrolhead and above generates beautiful in car video recordings with all kinds of data overlaid, ready to be presented - e.g. on youtube. Even without video, recorded data can be analyzed using purpose designed views, making it easy to analyze and improve your driving performance.

Using online racing, you can use LapTimer in competition. LapTimer offers a Hall of Fame, allows watching you and your friends on track - all in real time. Compare your sector times, braking / acceleration points, and learn from each other.

You can start with your plain iPhone in the beginning and add external GPS and OBD II sensors later, step by step, and as you need it. LapTimer itself comes in three different editions: LapTimer Rookie is the entry level with all you need for lap timing; LapTimer Petrolhead is the advanced version including lots of video features, and LapTimer Grand Prix is the edition for professionals including Multi Cam recording, and advanced sensor and analytics functionality.

Please note that functionality depends on your device, the LapTimer edition chosen, and sometimes even external sensors added (like OBD II). Please visit our web page to get the full story. All edition can be upgraded later, all editions come with native iPhone and iPad support.

There are quite expensive stand alone solutions for track days available. Be smart and own the leading edge tool simply by using your iPhone and LapTimer. Besides the professional area, there is no known solution that offers more functionality than LapTimer does - across the market. As our ambition is to offer the best tool, LapTimer is enhanced continuously.

Great app. Here's how to use it.

I managed to figure out how to use the app in 5 minutes of playing with it. Easy instructions:

Calibration happens automatically. If you want you can force it to calibrate manually by hitting the wrench in the "Acceleration" page, but it's generally unnecessary.

To get automatic lap timing working:
1) Create your car and track at some point by hitting the wrench in the "Classic" or "Racer's" page. Select your car/track.
2) When you get to the starting grid for the first time on that track, hit the "More" page, then "POI List", then "+". This sets your current location as the start/finish line.
3) Hit Go on the "Classic" or "Racer's" page and start lapping!

4 stars only because Harry should be writing these instructions and not me. This app has far more features than any of the other track day apps out there; they're just harder to get to.

Very accurate

I spent three days at High Plains Raceway testing various laptiming software. Hands down this app wins. I used a Tom Tom mount and amazed everyone with the accuracy. My lap times on this app were within 1/100s of the transponder times! The ability to use NMEA data must have been key. I use the timer view to improve my times; the diff to ref lap is a very useful and advanced function. With this functionality one knows exactly how effective a new line was, immediately. The UI could do with some work because the font on the diff is too small. Use the iPhone accessibility menu to invert the colors for more contrast. This app works better than some dedicated loggers. Keep up the good work!

Great for DE track days

A friend at the track was using it, so I bought it on the spot and used it all day. A little tricky to setup a track the first time (if its not in the database). However, once the stop/start position was set and some interim "sector" points made, the app just worked great. Its really nice to be able to start it in the pits and stop it when lapping ends. I can't comment on accuracy, but the speeds shown are less than indicated on my speedo by 3-5 MPH, but its a BMW which are infamous for exagerating speed.

I haven't seen any information on if the iPhone 4 has better or more accurate GPS, but LapTimer is working on mine. My friend at the track was able to send me his Portland International Raceway map from his iPhone 3GS, but the waypoints were all bunched together in the wrong spot on my phone. Easily fixed by dragging them to the proper positions.

As with any app that uses GPS and sensors, the battery will go fast. Use a power source in the car.

Bottom line for me, this app is highly recommended for recording your lap times for HPDE days.
