Just wondering if anyone has tried any of the smart phone lap timer aps? If so what have you found to be the best? Lastly how do they work, the last thing you want it to have to use it like a stopwatch? Cheers

Harry's Lap Timer is the best.

Agreed. Really need the GPS cradle for the car to 1) hold the phone and 2) boost GPS signal / accuracy. I was pretty suprised at what it could do. That said I've updated to AIM solo for this season.

Me too.

Does harry's lap timer have set tracks or can it GPS a track and allow you to set the start finish??

HLT works well for my needs. Supposed to be getting an update this spring to allow continuous video instead of every other lap. This will be nice. Can't be beat for what it does considering what it costs, IMO.

I have Harry's Lap timer in my iPhone.

It always presents faster lap times than my Traqmate, and my AMB Transponder. It is amazing for bragging rights, even more optimistic than a 997 GT3 RS speedometer.

Why people with $150k+ track day cars cannot afford a decent data acquisition system always lets me wondering.

I also have a AiM Solo DL and SmartyCam that I haven't use, very likely to replace my Traqmate.

Mine's less than $150k so that's why I use HLT.

I use HLT + the qiwi ODBC info sender for RPMS, etc

I am going to try HLT does the video link up through Go Pro or is it off the phone??

HLT - so I am faster.

Mine's now worth less than 150k, so I use HLT

I will probably upgrade when I finally win a DE

Winning a DE is easy!!!

Start from the pit lane after the group is already on track, you will start from the back of the pack, and you will get plenty of point-by passing moving chicanes. Michelin slicks help as well, very likely you will get the most point-by in that session a win the DE.

I have compared HLT to a transponder on a few occasions and it is always very close (at worst 1-3 tenths off), often it is spot on, and never a consistent pattern of faster or slower.
