It’s super easy to create an auction and you the customization is just amazing. The finished listing look great and professional, just like the ones you create on GarageSale for mac. I’d say the app is worth the price and would recommend it for all the iPad users.

The User Interface: A cartographic interface is just beautiful and cute, there are several nice animations and overall the UI is just awesome and the Grid lens teams has done a great job with it. Its one of the most creative designs I have seen, and its really simple to use.

Taking Photos: There are a variety of customization possible. You can create grid or your own, change the grid color, border width etc. You can take photos by, either tapping each grid one by one, or, just tap the Shutter button and it will automatically capture each after a preset time interval, which you can change in the setting menu. (burst mode and manual shoot mode)

Editing: The app offers several filter that the makes the photos even more magical.

“Designed from the ground up, our 2.0 app brings what you want right to the front. The first thing you’ll notice is a new “home” screen.

Tap the “Edit” button and move your home screen options around, add new options or delete.”

As reported by sites like AnandTech, the folks at Chipworks discovered that Apple is using a different production process for its A5 processors. The company switched from using Samsung Semiconductor’s 45nm process to Samsung’s 32nm process, reducing the size of the chip by 41 percent.

The new iPad 2, referring to the $399 iPad, features a new 32nm process for the chip design. This made the chip nearly half the size, and made room for Apple to increase the size of the internals. However, the big gain in switching from 45nm to 32nm is speed and efficiency. Though the 32nm chip found in the new iPad 2 is smaller, and more efficient, it still scores similarly to the 45nm chip found in the old iPad 2. Scoring roughly the same in web browsing, graphics, and the Geekbench tests, which were conducted by Macworld. Many people won’t even notice a speed difference in day to day usage, even with the new chip design.

They also put the devices through battery tests, but the difference was so minuscule, that it didn’t really prove that the new chip was more power efficient. In some of the speed tests, the old iPad’s 45nm design beat the new design.

Yet Apple and third-party developers have set a new record: in 453 days since the original iPad came out on April 3, 2010, the App Store has more than 100,000 iPad-exclusive apps available.

It is no secret that the iPad development scene was fueled by the success of the iPhone and iPod touch. When the SDK was first released in 2008, thousands of developers began building and testing apps for the iPhone and iPod touch. With over 10 billion downloads, the AppStore is now becoming one of Apple’s prized possessions in terms of digital downloads.

With the current growth of the iPad, it would be no surprise to see a 200,000 app milestone soon. With Apple pushing automatic downloads, wireless sync, and iCloud, it is clear that Apple is trying to ensure an easy process of downloading, syncing and using apps.
