Portable syn calculator

#1
Is there a specific formula you can use on any normal calculator when you're out and about shoping to work out syn values? I've tried looking at the javascript code of the calculator on the website but the actual calculation isn't visible. I'd like to be able to check syn values of things in the supermarket instead of getting home and realising I can't have what I've bought!

Unfortunately not! The SW calculator workings are strictly guarded!

You could buy a food directory and take it with you, or why not make a list in advance and check everything before you go?

The only rough rule of thumb you can use is that if the food item contains no free foods (so things like chocolate, biscuits, etc) then 20 kcals = 1 syn (ish).

Hope that helps.

Have any of you thought of emailing SW with your suggestions? If you don't ask, you don't get - and they might be able to convert it to a mobile friendly site without too much trouble...

On my old phone, which wasn't flash like a blackberry or an iphone, just your run of the mill Sony Erricsson (easily the best brand), I could get onto the SW site without any problems...
