I hate it....A TOTAL WASTE OF MONEY....MISLEADING.....I have an iPhone 3G S , which should be compatible with this application....there isnt a Settings option as the screen prints above would suggest.... its innacurate in its recommendations....plus if you enter more than the the requirement that it does sugggest (which is not inline with the Canada food guide) it kills the tracking, which was already wrong in the first place....there are hardly any items listed under portions...its a waste of time, money and energy...GRRRR!
