With The App Store Closed For The Holidays, Today's Best Apps Will Resume Dec. 29
CrowdSync by Foxspring Labs Inc (Free, 11.2 MB): Watch or rewatch live public events, such as concerts, in an observation booth-like experience. User submitted footage is grouped by date and location to offer an efficient multi-angle viewing opportunity. Videos are previewed in a quadrant grid where you can switch among them quickly and easily to view in fullscreen on-demand.
MusicDrive Pro - Share Your Music by ageye ($0.89, 6.7 MB): If you're always changing your mobile music collection, than this is the music player for you. Along with access to the iPod library, it's also possible to create, manage, and play alternate music collections. Transfer and manage music right from a PC or Mac using the management software and a Wi-Fi connection. In addition, audio files can be copied between iDevices via Bluetooth.
Universal:Drum and Beat by Mobobo (Free, 19.1 MB): This simple and somewhat whacky DJ app makes it easy to create some funky tunes on-the-go. The suite of apps includes a beat box, scratchpad, sampler, and sequencer. WIth these, you can do some mixing of the 100 samples or recordings via the microphone.
Have happy and safe holidays!
