Lap timing software for your mobile phone...

no idea how it works but some dudes on the web think its great.

As quoted:

Racechrono is a great bit of software for Nokia S60 devices, especially those with inbuilt GPS radios (N95). Check out the additional software which renders the data in to an avi that you can overlay on track video.

and
There is also an app for iPhone/Touch which will measure G's using the inbuilt the accelerometer.

Arron, the only lap timing you need to worry about is "Am I under 34s a lap"

[Arronduke]

yes might need to slow down....

I've got RaceChrono on my phone. Awesome piece of software. Lap timing, multiple split timing, it draws a map of your course, measures g forces, any type of time trial you want, can export all the info to a number of programs including excel and google maps. I honestly can't rave about it enough. Oh and it's free.

The Nokia N95 also has a built in accelerometer which will give you g force readings.

the old some dude on the internet said this is awesome ay??? Is anything not rated as awesome by someone????

as a cheap option to a basic lap timer its probably not a bad solution with much more function, but to a proper gps lap timer id be interested in its accuracy.

Find out for yourself here.

They claim 'Lap timing with a normal 1 Hz GPS and RaceChrono achieves +-0.25 seconds accuracy or better, and with 5 Hz GPS the accuracy will be better than +-0.15 seconds.'

They also have a forum there, never checked it out myself but if they are talking crap you'll find out there no doubt.

Get that super flash GPS dash and see if you can hook up a slow down light on the last slpit time if you look like going under 34. You could win the B grade for years on end and get yourself a reputation for being a super consistent rider.

Henk... now that sound great....

Hookk it up the the ignition to cut the motor for 2sec if the lap time looks to good.

Now how would I do that?

Still think my sticker Idea is the best option
Cheap
No batteries required
And if its gets damage just print another one !

This one is Henk's version

Trudes had a program on her iPhone. I personally have an XT Racing lap time, although i've never used it at buckets. Would be really really interesting to have them on the same bike @ the same time.
From my guessing i would still suspect that the GPS one wouldn't be as accurate as an IR timer like the XT. Maybe i should let her borrow my xt next time!

Whats the cheapest phone you can buy which can run this? I need a new phone!

The lap timer on my iphone is pretty good, but it does require a little initial setting up and re-mounting it to the bike every time (as well as the added worry of crashing and smashing up your phone), however...... it does seem to give fairly accurate times, and is good as it keeps a record of your laps, gives you maps of the lines you rode, g-forces and lean angles (now that's a hoot to look at..... "phooooooo, look at that, I was pulling .6 Gs!!" )
The app cost me about $15 I think.

Go to their website and click on the download tab, it lists all the phones there it works on.

Believe me I don't need anything telling me to go faster. Last 3 laps on Sunday it should have said either "For gods sake don't crash" or "HE'S RIGHT BEHIND YOU"
What a blast, three laps trying to get past and 3 laps hoping like hell he was going to stay there. I think Daniel was about 6 inches behind me across the finish line, if I had pushed any harder I would have been doing a spot of gardening when the chequered flag fell.

Henk
I had a go in the A grade's last points race
I started at the back of the grid ( trying to stay out of the way )
Got lapped near the end by Tim & Gavin
I was 10th out of 11
But good experance for next meeting
I should be a bit faster by the time Arron finishes his FXR and is bumped up to A grade.
