Track Addict may be a more recent player to the game, but it’s quickly caught up to be a serious contender in this market. Like other track-oriented apps, it brings lap timing, video, and various sorts of data (including OBDII) to help you toward breaking personal records. It offers many options for post-session analysis with your regular data graphs, but also statistics and driving line analysis. Available on both iOS and Android devices, it offers a free version as well as a Pro Edition at $8.99. The Pro Edition lifts limits on recordings and includes live telemetry through RaceRender live.
Standalone GPS Timers
This category stands as the most popular, as it fits the needs of most casual track day drivers as well as grassroots racers. These timers are built around the concept of simple form and function by pairing GPS and accelerometer capabilities with a compact display. They can work totally independent of other hardware, while some allow for expansion to take in ECU data or video. Their robust standalone form factors allow them to handle racing conditions and to easily be moved from car to car (very helpful for driving instructors). The GPS functionality allows the timer to monitor lap times, split times, and speed with great accuracy. Some of the available options improve upon this by utilizing a built-in accelerometer that logs g forces in all directions. Some of the more affordable options limit you to reviewing the data on the device itself, which is convenient but not quite as intuitive. The pricier timers let you download the logged data to a computer, where you can study the information in-depth, build graphs and scatter plots, and put together detailed lap comparisons to pinpoint areas of improvement.
This sort of hardware can set you back anywhere between $150 and $700, depending on what you’re looking for. Even in the simpler, stripped down timers, you have the advantage of strongly built systems that will happily take the abuse of track environments. If you want to add features beyond just lap times and predictive timing, you’ll quickly find yourself at the upper end of the price scale but not without good reason. At this end, you’ll find features like data analysis on your computer, customizable displays, expansion for custom sensors, and OBDII/CAN compatibility. This changes it from a simple timer to a data logger that measures forces, speeds, and potentially channels like steering angle, independent wheel speeds, RPM, gear, and anything else that the vehicle ECU can throw at it.
This category of timers and data systems carries the best bang for your buck if you’re at all serious about finding more speed. There is a bit more of a cost barrier than a simple app, but each option here is significantly easier to install and work with than a permanently installed logger.
Due to its high functionality and ease of use, AiM’s Solo and Solo DL timers were a major hit with track day drivers as well as racers. The latest iteration capitalizes on the Solo’s success with even more to offer. This system collects data from its internal GPS and accelerometer sensors, plus an external CAN/OBDII connection if you opt for the DL variant. With the help of quality-grade internals, the data is more reliable and accurate than ever. It offers all of the standard features like predictive lap timing, customizable lighting, and displays, a massive database of tracks with the ability to create new ones, external video options, and data logging to review on the device itself or on the powerful Race Studio Analysis software. It’s simple to use it on its own, but there’s a lot of room for customization and expansion if you want it to act more like a full-fledged data acquisition system. The standalone Solo 2 lap timer retails at $399, while the DL version with CAN/OBDII compatibility sells for $699.
