Checking up on apps and how they use iOS system resources is handled automatically, but some iPhone owners want to know what's happening behind the scenes. AppSwiper provides a new way to visualize what apps are running at a glance, and to display the amount of RAM being used. If necessary, apps can be stopped with a simple button press.

For those with jailbroken devices, AppSwiper provides new functionality for $0.99 on the Cydia app store. Once installed, this tweak makes it possible to swipe up directly on a running app icon, which will display the amount of RAM taken up by the app. Tapping Kill immediately stops the app, freeing up system resources for other things. What's cool is that running apps are highlighted right on the home screen, by adding color behind the app name.

The iPhone has a variety of passcode features to help protect the device from prying eyes. Normally with a four-digit "simple" passcode, the iPhone unlocks as soon as the fourth number is entered. iOS users can set a complex passcode which includes letters, however when this is enabled an OK button appears. From then on, unlocking the device requires tapping an OK button after entering the password.

Now jailbroken iPhone users who use a complex passcode can skip the OK button with the free tweak AutoOk installed. Just as it's named, the tweak will automatically register the passcode OK button, making complex passcodes behave like simple passcode entry. As soon as the full password is entered the device will unlock.

We knew this was coming ever since Google acquired the Yelp of traffic apps, Waze, a few months ago. Google Maps users will now receive real time accident, construction and road closure reports from the Waze community, and Waze users will soon have access to Google Search and Street View.

Waze is a traffic and navigation service with over 50 million members. The Waze community uses its mobile app to keep each other informed about current traffic jams and road conditions.

"No one likes getting stuck in traffic," Google explained on its Maps blog. "That’s why the Waze and Google Maps teams are working together to harness the power of Google technology and the passion of the Waze community to make it easier to navigate your daily life."

Rumors of a gold iPhone have been floating around since June, but no one has been taking them seriously, until now. Citing "sources in a position to know," and other blogs such as iMore, the normally reliable John Paczkowski of AllThingsD, claims Apple will release an “elegant gold tone" iPhone in September. But why?

As iMore points out, the rumored iPhone 5S is only expected to receive a bump internally, not externally. Perhaps Apple is just trying to spice up what could potentially be perceived as another "boring" iPhone S model launch by adding a third color option. According to Paczkowski, Apple probably chose gold because it's "the easiest colors to anodize," and it is a "sought-after color option at the higher end of markets like China."

Over the last few years Tower Defense games have become watered down and uninspired. The genre has fallen victim to copycat developers who spend more time coming up with goofy concepts rather than tapping the format’s potential to create new, fun and challenging games. However, there have been two diamonds in the rough for Tower Defense fans: Kingdom Rush and Plants vs. Zombies. Both started as free flash games, and both have found well deserved success on iOS and Android devices, making them two of the most popular current Tower Defense games available today.

In 2013, Ironhide Studios released the long awaited sequel to Kingdom Rush, and PopCap (now owned by EA) released Plants vs. Zombies 2: It’s About Time. Both games quickly rose to the top of the App Store Charts soon after their release, and both were well received by fans and critics. But which game is the best Tower Defense game currently available for iOS devices?
