Harry's LapTimer Rookie

Anxiously awaiting petrolhead version. Excited

When I started using it I realized it's useless for data logging unless you have a fast GPS. If using a phone GPS all of the collected data will be coming in at a rate of 1hz which is not granular at all and makes it useless for analysis and video overlay. Other apps do not do this. I have emailed the developer asking for a refund, the initial response was very prompt, asking me for a transaction number. He replied saying google issues the refund. It's been over a month and no refund.

Incredible app and developer. Basically implimented every request of users. Amazing commitment. Deserves to be a millionaire.

Used the new update. Worked perfect on my Android S5

It's powerful but the UI is really confusing and hard to navigate.

Easy to use and great for improving one's personal best on the track.

I had to reinstall my phone- I can't see my upgrade to petrolhead I purchased through the app. How do I get my upgrade back??

Everything you need for track days

App didn't work! Says "No fix" didn't pick up GPS signal. So disappointed as I didn't get to find out my lap time. This app sucks.

Harry's lap-timer is the best track day timing app

Works better than the other solutions out there. Simple to use interface

Harry has wonderful customer service and actually looks into troubleshooting his app when things get funky and weird. I appreciate his efforts in such a wonderful app and the constant updates!! Thank you Harry!

Can't wait for next track n test day @ brands Hatch with "Arcee "

Incredible app and developer. Basically implimented every request of users. Amazing commitment. Deserves to be a millionaire.

Loving the new Harrys Laptimer v18 for android. Answered all our prayers with the new "Gap" View mode!

Simple to use, easily to load maps, accuracy is there. What can you still ask for? The next version if comes with Video Recording, I will still purchase. I have been using this apps since IOS all the way until Android. Will still stick with it.

Awesome app, clearly the best of its kind, but does use a fair bit of memory.

Brought it and used it yesterday for the first time at the race track. Used with Galaxy S4 and very happy with the results it put out. Would love to see the Petrolhead and Grand Prix edition out for it so I can get the full Harry's laptimer experience. Thankyou very much

Harry's lap timer has been on iOS for sometime, I've been waiting for the Android porting of this app for months, I can't wait to get out and use it, if it's anything like the iOS version it'll have been worth the wait.

Great app but when do we get the Petrolhead edition?

Not only does the app work flawlessly, but (unlike that other lap app) is actually supported by its creator. I used the beta and the support is fabulous. Harry's is THE laptimer for android.

This is a great lap timer for android with a lot of features and a very active developer. It works without a problem on my S4 with an OBDLink MX and a QStarz GPS. Great for the track, autocross or just timing your drives to work. Looking forward to the future versions so I can overlay telemetry onto my GoPro videos.

Thanks for this, a great addition to the play market, been waiting for sometime now to get this app on the Android platform, this is by far the best mobile based lap timer ever, with support to OBD II and external GPS, big variety of export options, and hopefully soon GoPro connectivity (like the iOS version have), your track days and even fun runs and cruising sessions will be a happier place, thanks for a great app that we looked forward to and envied iOS users on it for so long :)

Can't wait to use it. Thanks for porting it!

As everyone knows, Harry's Lap Timer has been a staple at any high performance driving event...that is if you were using iOS. In fact, I was considering buying a used, non-activated iPhone just for Harry's software. But thankfully, now I don't have to since it's available on Android. I've tried other Android lap timers in the past, but nothing offered a full solution that combined both lap timing and OBD sensor readings (note: you need an OBD reader for that part to work) in one slick, sophisticated package. Harry's Lap Timer is fill an important niche in the driving community that other apps haven't been able to match.

Harry's lap-timer is the best track day timing app

Bugs have been fixed. Still lacks full functionality of the iPhone versions and the interface in clunky. You will have to search the forums to find out how to do stuff, but I finally got ODBII and video overlay working. :)

Works best of any application I've downloaded. Maps are killer! A+

The only app to get for if track your car. The bonus; this is the most well supported software you will ever own. I have emailed Harry a number of times with questions or suggestions and he always responds promptly. I have seen update addressing an issue I had brought up days before. I've been in software development for 20 years and you rarely see this level of dedication.

This is the best! Such good video.

Since the android version became available this app has only improved. Now with petrol head it kicks all other apps of this type to the curb. I can run it on both my droid bionic and my Nexus 7. A must have for track days. Thanks Harry!

I've run most of the rest of the Android track timing apps and Harry's is the best.

Done the in app upgrade to petrol head, got a Google receipt, but the app remains on rookie, phone is a note 1, sorted now just pressed upgrade twice and 2nd time it upgraded

This app is amazing for honing driving skills and repeatability. I just opted for the Petrolhead Add-On and couldn't be happier, now after a few data collection runs I can try to capture my best laps with HD video. Fantastic!

The Best Lapping Day App in the Play Store! I own both the Android and iPhone versions of this app and while the iPhone version is more mature, the Android version is rapidly catching up and already the best and most accurate in the store. With the latest Petrolhead release, it has just gotten better, it is a shame I can't post a review on that app! Keep up the awesome work Harry, my Mercedes race car thanks you with my wallet! ;)

The best smartphone driving app available comes to Android! Thank you Harry.

Simple to use, easily to load maps, accuracy is there. What can you still ask for? The next version if comes with Video Recording, I will still purchase. I have been using this apps since IOS all the way until Android. Will still stick with it.

Anxiously awaiting petrolhead version. Excited

Such a good app! Trackmaster has been buggy for a long time, and has not been fixed. The Bluetooth GPS in Trackmaster is busted. In Harry's it is great. Samples the Garmin GLO at 8-10hz. Can't wait for the fully featured app to come out.

It is not made clear enough that the Android version of this app does not support video, unlike the Apple version. No video = no point. I didn't find out until after I paid for it. They claim to be adding video next year but you will have to pay even more money to upgrade.
