Why buy a cow if you can get milk for free? That's exactly what iOS device owners should be thinking before checking the cart out on the App Store. Apple and iOS app developers always have freebies in store no matter what. So if you can wait for them to go down the sale rack, that's great!

Here's a list of best premium apps of the day that have gone free. From the costlier US$28.99 Portfolio Armor to a travel safety app, here are the best free iOS apps you can get now:

Portfolio Armor (US$28.99)

Portfolio Armor helps you hedge your stocks and ETFs by showing you the optimal put options to give you the precise level of protection you want at the lowest cost. You enter your US-traded stock or ETF position, and the maximum downside risk you are willing to accept for it (your "threshold").

Portfolio Armor then uses its proprietary algorithm to instantly scan and analyze all of the available put option contracts for the stock or ETF, searching for the optimal put option contracts to most economically hedge the position.
