When Steve Jobs introduced the very first iPad, one of his big statements was that the 75 million iPhone users in the world already knew how to use it. Well, many of those users were suprised to discover that five of the built-in apps that they had grown to love on their iPhone were missing on their iPad. Namely, Clock, Voice Memos, Weather, Calculator and Stocks. Rumor has it Apple didn't think those apps would scale to look good on the bigger iPad screen. Since then, Apple has added a clock app with iOS 6, but the other four are still missing. Fortunately, many great developers have filled that void and proven that, not only can these apps look good on the iPad. They can look great.
