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.

Fix the darn app already
So many bugs in each version/update! Now I can even add a 2016 Porsche cause it doesn't recognize it!!
Its great when it works.. But it does rarely do its job
More bugs than a Motel 6!! And every update adds more of them. Have the app on the 6plus. Everytime i want to record the app crashes in the middle or just when i want to turn it off after the run. Im first time at sonoma with ZERO footage after trying to record for a full track day. It crashes and restarts the whole phone way too often. I cant erase videos because it crashed immediatly if i go in the housekeeping screen. It also crashes right after overlapping a video "succesfully".. If the app wouldnt be all that buggy it would be great.
The #1 accessory you can get to go faster on the track!!
I kid you not- as a weekend track addict (I try and do about 6-8 weekends a year) I find Harry's Lap Timer to be the best investment I have made that has made me improve my times! Being able to capture consistent data points, sector/lap times and being able to overlay video (with MultiCam support of GoPro!) allows one to see where they are doing well and where one can improve.
My favorite things about the app:
* support for OBDII sensors
* support for external GPS
* support for multi cameras (iPhone, iPad and GoPro cameras)
* in-device support for overlaying multiple videos, data points from sensors on to track map
* ability to set a Reference lap and compare all other laps to it
Only a fellow track addict can develop such an app - and it shows how well it's been written!
Best app out there for a weekend racer
To say this app is anything less awesome is insane. In my opinion this has been the best purchase I have made from the App Store. The app itself has helped me to become a better driver at autocross events as well as hpde events at the local race track. It allows you to overlay data from sensors you have plugged into your car or phone that help create videos that blows my friends and family away. I highly recommend this app to any weekend racers out there. You will not regret it.
The best timing app or AutoX and track days, and helped me win my first race by keeping me on pace for 20 laps
Great functionality, UX needs work
By Andrew Khoury
Fantastic app, very accurate lap times, and great telemetry data. The UX is pretty clunky and could use a design overhall.
Best track app!
I reviewed other versions of this app in the past, and this review is going to be more of the same praise. Harry's GPS Lap Timer provides as comprehensive a solution as the iphone can handle, performing much of the same functionality as the vastly more expensive dedicated timing solutions, requires virtually no setup at the track, and just flat works!
Used the Petrolhead version at Indy Motor Speedway this past weekend (my 7th event this summer), and impressed my garage-mates with the timing and video the app produced.
Additionally, I had a question over the weekend that I posed to Harry; he responded very quickly, and I was up and running for the next session. Brilliant app and fantastic customer service!
I just made my purchase and have not used it yet. I have heard great things already and am excited to give it a go. I had some questions and was able to get answers back quickly via Facebook. Thanks again for all the help Harry!
The most frustrating app I have ever used
Let's see: Awful interface, very unstable, exceptionally difficult to use, inaccurate, full of bugs, overly complex, expensive. These are some adjective that describe the app. Only one tutorial that is available online that is both outdated and useless.
Great idea for an app awful execution
5 stars, great app
I'm really enjoying getting to use Harry's. Lots of features and ability. I strongly recommend this app to anyone who enjoys track time.
Easy to use and an excellent way to take a second look at what you did on the track!
By 05 STi
I was looking forward to this app helping me to improve my times on Streets of Willow. After 3 sessions of running I gave up, the app never worked! A guy at the track said it works sometimes. Very disappointed! Wish I could get my $ back.
