Been a user for few years and it’s quite honestly one of the best lap timer solutions (and not just among mobile apps). Other professional setups will cost you over $1000 when you factor in hardware but this app will fine on its own give you nearly same level of data acquisition. Best of all is Harry’s dedication to the community. He personally responds to all troubleshooting requests despite the majority of questions being repeat asks already covered in his FAQ and provides regular feature updates to the software. Anyone complaining about user difficulty didn’t spend the 5 mins to read the user guide.

I’ve been tracking Porsche’s for years. I’ve had $1000 systems such as Traqmate but that’s no longer sold and windows only support is tough. Porsche Track Precision app is terrible but HLT is super reliable. I use an external BT GPS and a BLE ODB adapter. Overall you just can’t beat HLT for cost to realizability to being able to dig into data. My only wish is if I could find 991.2 GT3 custom PID info for brake pressure and ESC like the Porsche track precision app. Thank you Harry for continuing to improve an already amazing app. PS I use the Grand Prix in app upgrade, worth every penny.

I’m completely blown away by the features and functionality of this app, and the documented support. There are so many things you can do with it, an incredible array of supported accessory devices, and with all the complexity available there is documentation and online support that makes it easy to work with. Best value it track software out there.

Harry‘s Laptimer is a very capable performance analyzer. Video and GPS based analysis with that much flexibility is unparalleled on the iPhone. I recommend to visit his website for the excellent user‘s guide as the app can seem intimidating at first. Excellent support from the developer is also available through the forum there.

Honestly disappointed to see this many users accepting such a subpar product. The user interface is viscously difficult to navigate, and missing key ‘ease of use’ that you would expect with a track tool. Overall, between lost sessions & general frustration with the UI, spend your time/$$ investing in other more reliable timers such as RaceChrono or TrackAddict from HPtuners. There are too many other aspects that require attention on race days to get this fed up with what should be an easy to use app.
