Bought at the last minute for a track day Might work ok in a car but certainly not on a motorcycle as this doesn t work from inside a pocket     Total waste of money Pierre SF

App seems to have a lot of functionality but it s not exactly plug n play I can t fiddle with it while on the track so it gets frustrating when it s not working as expected             Lots features but needs to be easier to use MaliceRancher

I recently purchased this laptimer rookie I m a novice racer just looking to make improvements in my street car mk5 gti this is perfect for what I want It tracks your lap times as well as a track map to see your g s in the turns It s a great app The folks are great with support as well                     Laptimer Will Christian

Worked great at a recent track day Recorded lots of good data and times Def worth it                 Must buy for saving times Felliph3

I bought the rookie version I used it for lap times Works great Will mount it properly in sept at vir and use some more of its features                     Rookie version Bossssssssssss

Great that I have been using since the good old PalmOS days Runs fine on a 4 S but needs external GPS on a 3S Love the external gadgets 5Hz GPS OBD and camera feeds                     App Fab FPR2010

Still one if the best apps I have ever purchased Continually updated refreshed                     Best Joonyaboy

I ve been using this app with the Tom Tom mount through several releases Absolutely phenomenal With the new iphone 5 and improved processor I m hoping the video can be made continuous otherwise wonderful tool                     Outstanding Buki5

We are not a big dollar team weekend warriors all the the puts a ton of technology in your hands There is a lot to go through there is a ton of features if you want to spend a lot of money for a single function device have at it Thank you for making a great tool at a great price I can now pick my jaw off the ground this app is Awesome                     Wow Moose Dancer

Although a little confusing to figure out at first I m amazed at all the information it relays to me Very helpful at the track plus cool to find the best way to school Harry also updates the app quite often making it better and easier to use every time Definitely worth the 4 99 Thanks Harry                     Excellent App Jerry Tunney

Total waste of 8 99 Didn t work for a SINGLE LAP in a full day at the Thunderhill track I attempted to get my money back but was stiff armed by the developer Harry and denied by Apple Be forewarned apparently the app doesn t work is not a vaild reason for getting a refund Really I feel ike I ve been robbed by both Harry and Apple Don t bother with this one     doesn silicontraption

This is a great application to use for track day data gathering I ve been able to use it to shave time off my laps and to help diagnose problems I ve had with my car For the most accurate results you cannot rely on the internal GPS The TomTom mount is quite good There are others listed on the Lap Timer web site which also work quite well according to the author I haven t tried them but I have no reason to doubt I ve actually ordered one of them since my TomTom mount isn t working but haven t tried it yet Finally if you ever have any questions about using the application or even enhancement ideas the author is very responsive I ve always had an answer within a day and in one case where a new track configuration was being introduced he was up early in the morning getting the new config set and ready to use There s even a forum specifically for the application Harry keep up the great work                     Great Data Logger savowood

I just used this for the first time at Summit Point and it was great The lap times were within 1 10th of a second and often within a few 1 100 of a second compared to the transponder Worked great every time and did not use data and the battery did not even go down very fast Amazing App Used with an iPhone 4 no Tom Tom kit                     Great App Brent19

Another track buddy told me about Harry s Lap Timer and just looking at it while sitting still in the car I couldn t figure it out But I thought for 5 99 it may at least give me a rough estimate of my lap times until I get a real timing and data system I started reading the help pages and got more and more amazed as I read I got to the video part and thought why did I not buy the Pro version So I upgraded right then and made a date with the track a few weeks later Standalone products that do all this go into the thousands of dollars Yes HLT isn t as flexible as the standalones but it s literally 1 100th the cost At the track this app is right at home There was already a map for VIR so I just downloaded the track map turned it on and away I went I bought a tomtom iPhone car kit but it didn t have the iPhone 4 adapter so my first day was using the internal assisted gps only And really it wasn t that bad considering there isn t much cell signal anywhere near the track Some laps were better than others signal wise and it didn t provide a good baseline due the inconsistency but that was expected That night I bought the Pro version for my old 3GS and took it out the next day plugged into the tomtom Perfect reception and consistent timings I need to figure out what software to do the data analysis in now The built in analysis pack is good but the screen on the iPhone is tiny for all that data I do like the lap time and comparison to a reference lap analysis I haven t tried all the modes yet but what I have used classic timer video speedometer analysis has been worth many many times more than the 15 bucks for the pro version Considering this is one guy developing this app it s totally 5 stars I have a few wish list items for subsequent releases choose how many laps are recorded on video before saving to phone allow for background video recording and the classic timer foreground I don t need to see the video while I m driving I do need the timer up add a line from the center to the moving dot on the friction circle have the option of time in comparison to your best time for the entire lap not just a sector allow for one button press and record gps overlaid video without creating a lap for impromptu mountain drives I have all kinds of ideas Harald if you need someone to test just let me know Thanks for creating this incredible app                     What s not to love about this app Tcpsoft

Not good at all hard to understand don t spend your money in this app you won t be happy     Laptimer Carlos 224

I haven t had an opportunity to use this on the track yet but it looks pretty nice The only disappointment I ve had so far is that it won t run in the background while I simultaneously sp record video on my iPhone 4                 Nice app Gernby

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                     Great for DE track days Zenbob1

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                     Very accurate Tenthumbd

One of the best apps in terms of using the full capability of the iPhone Just great You just need to learn how to use it check his website for more detail Once you figure it out it will blow your mind how cool it is I can t wait for more updates it keeps getting better and better Must have for any truck enthusiast                     This is not only useful but super cool Hdias4

This app is great for the track day enthusiast The ability to easily set up intermediate triggers using google maps is fantastic Once you know what you are doing with the app you will fall in love with it The PDF and google earth track map exports are awesome and allow you to share your hot laps with anyone I m looking toward to more timing views It would be great to have a view showing the gps reference gap current time and best time in huge numbers on the screen Keep up the good work Harald                     Loaded with features Tekyguy

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                 Great app Here s how to use it lapped_u

I am really impressed by this app as it fills a need for the right price I have wanted a GPS accelerometer logger for HPDE events for the last several years but have not been willing to fork up the 600 1000 this would cost Although this app does not give the same precision and reliable performance as such a dedicated unit it is functional enough to do what I want compare laptimes and analyze sectors where I can improve as well as provide data for later video overlay I looked at several other apps but they seemed more expensive and less functional that this one pros nice realtime accelerometer view useful GPS status information easy export of data in a usable format and nice viewing of individual laps cons still needs work in some areas for example I have not been able to get the accelerometer calibration to work as intended it never finishes the last two steps for the drive in a straight line and linear braking acceleration component Force calibration does not seem to do anything useful My workaround has been to position the phone uncalibrated using a swivel ball mount such that both axis are zero when level and at rest oriented pretty much vertically in portrait orientation and it would be good if the intermediate accelerometer data was used to augment the slow GPS update rate or at least was logged so that I could provide this correction myself It seems from the development plan on Harry s website that this is in the works so I am looking forward to the next update Keep up the good work                 great app but still needs some work kkiger

It is easy to turn off auto lock so that really isn t an issue however this is a terrible app There are no instructions and simply trying to figure out how to set up a track is hard Calibrating is a nightmare It s really no more useful than a stopwatch If you want a decent lap timer and data buy a traqmate     Not worth it Wastintime

This MAY be a powerful app but it is difficult to tell because there are no instructions on how to use it The website shows some neat screenshots but I have no idea how they were achieved While I do get some instant data I can t figure out how to get the track mapping and lap timing shown on the website The stilted English doesn t help I tried using it in my racecar once and only got wrong data I know my MG Midget doesn t go 212 MPH as much as might want it to I also could not figure out how to keep it running for any meaningful length of time as another review noted And why must I agree to the license EVERY TIME I launch the app I wish I could either get my 4 99 back or get some instructions that might unlock all the secrets that are hiding in this app     Useless without instructions The Stig Again

Good application has lots of nice features and is at a reasonabel price Don t expect a ton from the iPhone GPS system but it does well with auto lapping It s frustrating now in OS 3 0 that you can t disable auto lock I can t figure out how to keep this application alive without touching the screen every 5 minutes not easy while track driving Any ideas                 Good app jruben4

The app is very nice but the iPhone s GPS gets lost easily in corners my track maps look like spaghetti once I get into the corners Too bad because the app appears to have been well designed and implemented     iPhone GPS is not good enough Nirwana

I ve used this software on my Palm for a couple of years and now it s finally available for iPhone It s missing some of the Palm features but I m confident they will come This developer has always responded quickly to concerns and problems I have not seen any other software in the App Store that does what LapTimer does This is by far the best software for road racers on this platform Thanks for bringing this software to iPhone                 Great App Jakuta
