Details

Harry's LapTimer is the advanced tool for car enthusiast. It records all types of sensor data provided by your smartphone (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 800 predefined racing 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. 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? Recorded data can be analyzed using purpose designed views, making it easy to analyze and improve your driving performance. This includes several export formats including Google Earth.

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 smartphone in the beginning and add external GPS and OBD II sensors later, step by step, and as you need it. 

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. 

There are quite expensive stand alone solutions for track days available. Be smart and own the leading edge tool simply by using your Android smartphone. 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.

Please visit http://www.gps-laptimer.de for detailed information on versions, FAQs / documentation, in depth technology background information, online racing, and supported device configurations. Join our user community on http://www.gps-laptimer-forum.de to be involved in future development - all with first class support.

Please check http://www.gps-laptimer.de/Compatibility_Android.html for compatibility information and guidance on external sensors.

This is the Petrolhead Edition of Harry's LapTimer. The main differences compared to Rookie Edition are video recording in parallel to data recordings as well as full on device video overlaying. In addition, LapTimer Petrolhead features advanced analytics and online functions. 

Important: As a power app, LapTimer is quite demanding in terms of main memory and processing power. The Geekbench benchmark shows a good comparison of current devices and their processing performance. My tests using LapTimer v18 show you need a device scoring 1200 in the MultiCore benchmark to have fun. This means a device like Samsung's S III is kind of the lower end. Especially when recording and overlaying video, go as far up as possible.

In case you have purchased LapTimer Rookie already, please check the Add-ons view in your Rookie app for an InApp upgrade from Rookie to Petrolhead.
