Best track phone app

[sambb]

Might be doing a track day soon at SMSP that doesn’t have timing. What’s the best iphone app that does splits etc ?

Have a look at the RaceChrono Pro app ($24) with a bluetooth GPS unit, something like a Garmin Glo ($100).

Cheers

I use the free version of racechrono at Winton just with my phone GPS and it's within a few 10ths of the track timing

Thanks guys. Out of racechrono, track addict etc it looks like the best one for me. It seems to do splits and let’s you know if you’re up or down etc. I only have an iPhone 6s so not sure how good the gps in it will be so I might just go ahead and get the glo 2 anyway. Initially I was bummed that they didn’t have timing but now I’m thinking for a first crack at the GP circuit it’ll probably be better having split times, progress in splits, best lap comparisons. Etc.
now I need to just choose which beam I’ll run, bleed brakes, redo oil cooler and finish the tune by the 19th!

the lap times are pretty close to the track timing to give a rough idea but if you're going to look at it seriously with splits etc. then I think Gary is right.. it would be best to have a bluetooth GPS. The map overlay of my laps show a lot of straight bits where the GPS lost resolution

One of my sessions shows an optimal time of 1:36 which I doubt very much

I've read a it about how the hones receiver will 'wander' depending on the satellite fix. Missed laps are apparently a result of the car 'wandering' outside of the width of the finish line. Apparently you can go in and spread the width of the splits and finish lines. Yeah I think the remote receiver is the way to go but I dont really have time to oreder one now before next monday unless I can find one at a retailer. The GLO 2's are a bit exy so I'll see if there's a cheaper option.

Best price I found is $139, it isn't too bad.

You could make one tho
