RaceChrono

Awesome app. Great for anyone looking to see how they can get faster

Very nice.

Brilliant app! I use it in conjunction with a Garmin Glo in my race car. It provides valuable information when testing setup changes! The interface is easy and everything just works the way it should. I love the fact that the data can be exported to Circuit Tools for analysis later on. The only thing I find lacking is the fact that there is no way of selecting more than one session at a time to export directly to Dropbox or email. Some sort of session backup system to a linked Dropbox account would be welcomed as well. I use Dashware to overlay the data on my onboard videos which makes the videos a lot more exciting. Thanks for a great product!

Brilliant. Great way to get some data logging out of a historic single seater. I did find it was a lot more accurate when I cable tied the phone to the steering wheel vs just leaving it in my race suite pocket, guess 3 layers of fireproofing does mess with the GPS. Will be buying the full version at some point soon.

Great app. Would be good to get a version that can work with the Samsung gear s3. Much better than carrying the phone around in the car while on track.

Please add some interface for edit files information, colours, etc

Only thing I can't find if possible is to change start time for session. When racing it logs the warm up lap as your start, also would be good to allow the clock to start as soon as you move x meters. On my points from using it as a race logger.

Details, great library, accuracy

Great for trackdays!

The data analysis tools and presentation in this app are better than anything you would spend $100s on for pro level software. It's simply outstanding. The timing app is very good - I wish it was customizable in terms of layout.

I got a big fast car and this app manages to still keep up with me even if no one else manages too. I can now sell my son to colombians. Thnx for dis

Love this app i use it on my trackdays and its perfect. I upgraded to pro and even better and great customer support

Very good. Very good value for money. Missing brake forces and speed for each individual wheel as well as steering angle. But how to get to these non OBD channels?

Best lap timer app for free. Pretty accurate and very easy to use. I may upgrade to Pro version this season. I love it!

Using it for 3 years, top notch

App is good, Just want to know when will be able to look at the data on the internet ?

It's been a huge part of my growth in going around Killarney race track in Cape Town, South Africa. Enjoy the data straight after my session and later on I export and email the data to myself. Then I use Dashware to overlay the data with my synchronised video. Excellent!

Doesn't give imfo for vbox app for android. Does everyone sleep with apple?

There is a mistake between google maps track photo and racing lines(+-2meters). Sometimes the lines are passing out of the track.It should be a way to move the race chrono racing lines in Google photo to correct the gps error.

I've paid for the unlock but the video overlay dosnt work. I want a refund

Great apps for track day

This app is awesome, and I used it back in October when I went to VIR....BUT IT DELETED ALL MY STUFF RANDOMLY. I can't race for a while, but all my lap data for the 3 sessions I timed that day just randomly disappeared

Esta bien pensada y es facilí de usar y parametrizar tus circuitos. El desarrollador atiende las peticiones y contesta muy rápido los correos. Lástima q exportar sea opción de pago y el precio no es bajo.

Great app for the track.

I was skeptical, but it works pretty well.

Excellent app to give you stats on your track time. Still figuring out all it will do

Sprung for the pro version. I can use this app sync up to my GoPro and a cheap $20 OBD-II Bluetooth transmitter that I have and create awesome videos with detailed overlays (rpm, speed, intake temp, throttle position, etc.). You can also record from both a GoPro AND your front/rear smartphone camera simultaneously, and then overlay the two videos to do picture-in-picture. I've been playing around with it during normal driving but I can't wait to test it out at a track day this weekend!

Best track tool ever.

Even if u have a transponder, this app beat it hands down for its live timing.

Works well

Amazing

Greattt!!!

Τελειο!

I use this for lap timing mostly. The ease of use is great. I also pull logs from it to add/compare to multiple source logs and projects. As stated, an external GPS works much better than the device GPS.

Run free version on Samsung Galaxy S5 w/ Android 5.0. Have used for 2 track days. Worked great. Downloaded track(s) to phone. At start of session simply press START button while in pit and but phone in center console. Stop it when back in pit. RaceChrono "finds" the track I'm at by itself, nice. Very helpful info for comparing my driving performance lap-to-lap and even session-to-session. Easy to see where I slow too early or accelerate too late/slowly. Being able to see my driving line on the map is cool. My only complaint is a limitation of the phone GPS, not RaceChrono. The 1MHz phone GPS is too slow to accurately measure position and speed at track speeds. Need to add an external Bluetooth 10MHz GPS receiver; about $150. Read RaceChrono forum for recommendations.

I've been using this software for years now and it is absolutely amazing!!!! I'm racing a 1000cc bike and the difference between this app and the track official lap timer is only 0.01s! My only hope is that they will add a lean angle recorder as well to make it 100% perfect! *I'm using it with Qstarz BT-Q818XT GPS receiver in order to get accurate lap times.

Doesn't work, never connects to a GPS and poor layout.

Used it for a few carting sessions and it works perfectly. I get my lap-times printed out from the track's timing system and they have only a few tenths diff from the ones I get from the app. Really impressive.

Just needs to ad time when going in straight line,it has distance by km and meters,so brilliant for checking exit speeds but no time when going in straight line.others wise very good.love using it.and was spot on with professional equipment a few times at race events.good work guys.much appreciated
