Reports of a biometric sensor in the upcoming iPhone 5S have been floating around for some time. However, with the release of iOS 7 beta 4 to developers 9to5Mac has posted new evidence that the fingerprint scanner is real. The code reveals a folder named "BiometricKitUI.axbundle" featuring the building blocks to run a biometric sensor.

According to sources, Apple has completed work on the user interface for such a feature, which would presumably unlock the device. Instead of typing a passcode, all that would be needed for a home button fingerprint scan is to press the button. The leaked strings indicate that during the setup process, a fingerprint graphic would change color when registered.

The stock iOS Clock app has several useful features, including alarms, a timer, world clock and stopwatch. The stopwatch function is great for clocking lap times, but there aren't any options to save these numbers once collected. Now thanks to the jailbreak tweak Stopwatch Pro, the iOS clock can be even more useful.

There are no settings to configure once Stopwatch Pro is downloaded and installed via Cydia. The tweak simply adds a Save button to the stopwatch, making it possible to save a time or a series of laps before resetting and losing the information. All of the saved times can be labeled in different sections to keep track of events and group related measurements.

After giving its developer center a major overhaul, Apple has finally released iOS 7 beta 4. Apple allegedly plans to release two more beta versions before releasing the gold master version in September, according to BGR. The new beta brings a ton of fixes and tweaks. You can see Apple’s lengthy iOS 7 beta 4 change log below.

Some new discoveries in beta 4 include minor evidence that Apple is adding a fingerprint sensor under the Home button, a less confusing Lock screen, notifications for completed uploads, and new Siri suggestions. Apple also released a beta version of iTunes 11.1 so developers can get an early look at iTunes Radio.

Tired of having to search Gmail, Google Drive or Dropbox individually while trying to locate an individual file? A new app by Peoplematics allows you to search for emails and files on your iPhone at the same time. Findit features a simple UI that is easy to use, but where it really shines is how you are able to search for items. The app allows you to search for a file or email by entering a person's name, a time or what type of file you're looking for. The time and type options are interesting features because you may not always remember the name of a file you're looking for, but you may remember when you downloaded it, or what type of file it is.

You can either begin a search by typing in a keyword, or by tapping one of the three search categories. For example, you can tap the "Search by time" option, then select a time frame, and then add a keyword to narrow your search. The UI is really simple to use, and the many search options plus filters allow you to easily narrow your searches down until you find what you're looking for. However, there are not many options once you locate the file.
