This Saturday, as I can not navigate. I decided to find app's kitesurf. I have liked these: You can search without spot's offshore winds and other parameters. It is based on WindGuru play.google.com/store/apps/details?id=com.zerouno.spot
This allows calculation of material parameters on kiteboarding
play.google.com/store/apps/details?id=org.bitpipeline.app.kitesurfbuddy
I have also found this app for iphone with cool spots for sports https://itunes.apple.com/de/app/splocs/id433281938?mt=8
i'd red thumb ya but apparently i've over cooked all my negative thumbs, so have to green thumb some posts 
i'll get back to you 
its easier to just take all your kites to the beach. look at the water and pump up your desired kite.... sounds simple huh!

Don't forget to pick up a handful of sand and throw it up and study it's drift and direction.
I've developed a formula to work out what kite to use. If any IT person can help develop an app we can make a mint:
light wind = big kite
moderate wind = medium kite
strong wind = small kite
very strong wind = very small kite
I thought it was more like:
Light wind = mow the lawn, wash the car, drink beer
Moderate wind = surf Seabreeze whilst waiting for the live wind readings to increase
Strong wind = medium kite
Very strong wind = small kite and fun by the bucket loads.
I have a better app formula:
Kite size = Weight divided by (Wind strength (knots) divided by 2.2).
Wind strength as having power but not being overpowered.
That is the mid wind range of the kite.
Round to the nearest number.
KS=W/(KNTS/2.2)
lol

Funny I've got he same problem so I just green thumbed you !

That is "O" for Awesome mate. I decided I like to be more powered than you so my variable is 2.6.
Kite size ?weight kg?wind speed knots
21? 82?10
14? 82?15
11? 82?20
9? 82?25
7? 82?30
6? 82?35

Erm - how tested is this - your formulae suggests that in 30knots at 90 kilos I should be on a 6.5 - that's pretty conservative!!!

He said to round up to the closest size.
30/2.2 = 13.64
90/13.64 = 6.59 = 7 metre
Sounds pretty much right to me!!!!

Light wind.. Mow the lawn.. bahahah.. 95% of over 50's in Perth
Very strong wind.. Get skull dragged becase you dont know how effectively use QR.

Yeh this works out on the money for me, nice one!
Although if you need a formula to pick you kite I'd be a little worried about kiting.. Also the old data principle of crap in crap out applies, it's only good if you know exactly how much wind there is and are honest about what you really weigh..

Great! If I want to kite in 1kn I just need a 198m2 kite! Just fired up the sewing machine. :-)

Actually you're onto something there. How about we turn that wind-speed app on the iphone/ipad into a more generalised one with the above categories and pictures, videos and wind charts to match popular brands of kites and boards? I am serious! And I know Obj-C and Xcode.
