Comments on Harry's LapTimer Petrolhead for Android

★★★★★ Darren Lattin · Oct 18, 2016

Great app, awesome developer! Harry's is a highly accurate tool for recording lap times, analyzing data or just making really cool videos overlaid with on board telemetry. While setup at first appears complex, it's actually quite easy to get started using the in-app guide or online tutorials. I've even created, submitted and had approved a certified track set for my local motorsports complex. However, what sets Harry's Lap Timer apart is the responsiveness and helpfulness of the developer. Kudos to Harry!

★★★★★ Wilson Steele · Sep 7, 2015

Best in car timer & data system Absolutely amazing track day app. Preload tracks, and it does everything else even overlaying GPS data on video. Systems costing hundreds of dollars more don't even compare...

★★★★★ Martin Lynch · Oct 9, 2016

Excellent Track Day App Takes a little bit of reading to figure everything out but well worth the effort. Absolutely love this app - hands-free lap timing, lots of analytics, connects easily and consistently to my ODB2 device via Bluetooth. Visit the site first and learn lots in order to get the most out of it - you'll be glad you did. Excellent.

★★★★★ Pascal a · Dec 26, 2022

Very nice app to analyze your laps or show them to your friends.

★☆☆☆☆ Colin Kerwick · Sep 9, 2021

Waste of money and if I could get my money back I would if I have known sooner it wouldn't work when I was doing track days on my race bike I would never have downloaded this app

★☆☆☆☆ Nathan Putnam · May 28, 2017

Lot of money (including the upgrade) to find out it doesn't support gopro triggering and overlay on Android. Use Track Addict, it's free and works great!

★★☆☆☆ Double B · Jun 28, 2016

Couldn't get video to work s7 Way too complicated. WTF with video???? Not user-friendly or intuitive. $20 and lost memories down the drain for track day today. Ridiculous. DON'T WASTE YOUR MONEY ANDROID USERS.

★☆☆☆☆ Sean Hall · May 2, 2017

I really had high hopes for this app. I took it out to the streets of Willow last weekend. In both recording sessions the overlay data is totally wrong in fact when I first started using the app I'm sitting still pulling 50 mph and 1G. It seems to me this app was an overly ambitious project for one guy. I hope that the issues can be fixed, and I hope that there's better videos on how to set this thing up and get it working. For example, one wrong finger swipe and one of my sessions was deleted. No warning, nothing. In addition, the interface is totally unintuitive. I think overall the app needs a complete overhaul to make it simpler as the app seems to have evolved into something totally different from which it been intended and the GUI is not designed for what it is today.
