The best voice recorder, weather, calculator, and stocks app alternatives for the iPad mini and iPad 4

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.

Solving the case of the missing iPad apps: The best clock, voice recording, weather, calculator, and stock apps alternatives

Apple chose not to include clock, voice recording, weather, calculator, and stock apps, but luckily the App Store has great alternatives for each one!

Calcbot review: The best scientific calculator for the iPad

The Calculator app is one of those iPhone apps that didn't make it's way onto the iPad. It's a shame, because a lot of people, including students, travelers, and home book keepers would get a lot of use out of it. The most popular type of calculator is a scientific calculator -- it can do more than the basic operations (adding, subtracting, multiplying, and dividing), but isn't as different in approach as an RPN (reverse Polish notation) or as advanced as a graphing calculator or CAS (computer algebra system). So which iPad app is the best scientific calculator? Calcbot by Tapbots.

PCalc 2.3 now available for iPhone, iPad [Give away]

PCalc, one of our favorite iPhone and iPad calculator apps (see Leanna's PCalc review), has just hit version 2.3, and in celebration the developer has very kindly offered us a bunch of promo codes to give away. To you. But first things first:

This free update has many improvements, but the key one is taking advantage of the additional screen space on the iPad. You can now permanently show the paper tape, RPN stack, and memories onscreen in a new sidebar area. This was the number one requested feature from iPad users, and we're happy to be able to add it now.

The tape, stack, and memories have had a complete overhaul for the iPhone and iPod touch too, and are now easier to read across all devices, appropriately themed, and with enhanced email support.

PCalc is distributed as a universal app - one purchase will work on iPad, iPhone, and iPod touch. No need to buy a separate "HD" version. It requires an iPhone or an iPod touch running OS 3.0 or later, or an iPad running OS 3.2 or later.

Give away after the break!
