A well made full featured app Defnitely worth your money                     Mohammed Khoory

Doesn t work as described     Robert Lathrop

great app                     Andrew Reid

Like anything worthwhile it takes a little practice but once you do that this app works great I paired this app with an ODB2 Bluetooth and Garmin VIRB Support is excellent and quick                     Mark Centofante

Broken Can t grant GPS permission because of a screen overlay     Robert King

Just one question when I get a clip overlaid with export function why do the frame rate drops dramatically Is there any way to get better quality overlaid vdo that I can upload                 Pan P.

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 is was intended and the GUI is not designed for what it is today     Sean Hall

Great app have used it several times on many different tracks and it works really well The only thing I dislike is that there is no option for an account to keep all of your laps safe I ve had instances where I ve broken my phone and haven t been able to backup the laps resulting in a total loss of all previous laps It would be great if you had an option to create an account with auto backup of the laps                 ben o'connor

App shutdown 30 seconds into use at the track Overlay on both GoPro and phone cameras was non existent Currently in the process of attempting to obtain a refund     A Google user

Great for track days I use g force data to find where I could be faster                     bswat

Excellent data tool for the track rat Syncs with 10hz BT GPS well                     Marchi Lopez-Linus

The best for my track days with GoPro                     A Google user

Great app awesome developer Harry s is a highly accurate tool for recording lap times analysing data or just making really cool videos overlayed 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 LapTimer apart is the responsiveness and helpfullness of the developer Kudos to Harry                     Darren Lattin

The lap analysis features are better in other race apps I m looking for an app that can provide velocity and map position overlayed on a map and to be able to compare laps This app supports very little of what I need at the moment However video overlay works really well now after the new update             Update new version fixed freezing Edward Djrbashian

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                     Excellent Track Day App Martin Lynch

Have used Harry s GP at a few tracks in Florida and Georgia It works seamlessly and I have even interfaced with Vbox to take advantage of the 20hz gps However it s not necessary Excellent support Harry has responded to my dumb questions within hours                     Wouldn t hesitate to recommend Richard Demby

Clunky unintuitive and impossible to get the inputs properly synched It maybe is ok if works properly out of the box otherwise a horrible experience The config screens are anyone s nightmare You have heaps of little icons everywhere colour coded laps but without any explanation on what all that means And why do I have to click agree every time it starts Oh and it is way too expensive for the badly designed program it is I have wsted hours upon hours navigating the horrible interface avoid     Clunky unintuitive u0026 hard to use and expensive Istvan Horvath

The maim reason I went with this version of the app was because they promise of easy overlay with internal and external videos Unfortunately hardware encoding is not supported with my phone a OnePlus 3 Instead I m being forced to do software encoding and it takes more than 4hrs for a 20 min video It also doesn t support the raw video size from my AS200V Action Cam Then I need to convert it and compress it decreasing quality If it weren t for this I would give it 5 stars         Awesome logger bad for making videos A Google user

Accurate lap times it helps you analyze cornering speed Thus being a faster driver in the track                     Alaaeldin saleh

A great addition would be some kind of DragRace mode 201m 402m                 Really Good Paulo Groth

had a bad day at AMP with this didn t start properly when crossing finish line didn t want to film and do data it needs nashville superspeedway road course on it they re opening up again             bad day Tim Nygaard

Love it                     bassmn duc

The latest edition and updates have solved all of my issues No longer frustrated in Seattle using Android Thanks Harry I m glad I stuck with it I used it at the track this weekend and it was perfect                     Update Rick Shaw

This app is so much better than anything else out there and produces results a lot better than much more expensive solutions definitely worth every penny                     Unbelievably good James Fox

Very useful well conceived very well supported                     Excellent Peter Schwenn

This is my third year using it I love it Wish it was as android friendly as it is Apple friendly but works fine                     best bang for the buck Fred

I ve read and reread it Paid 20 for an app that is useless So disappointed Save the money by buying something that works I ve warned you     App description is inaccurate Marc Dillmore

Everything else is good             Video overlay doesn t work on android Dillon Brennan

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                     Best in car timer u0026 data system W Steele Racer

One thing i would recommend is the ability to add another phone or gopro like the ios version for android                     Steven Loosle
