Some people may find it hard to figure out which apps to get for their iOS device. I have my favorite apps listed below that every iOS device should have. Check it out and let me know you favorite. GOOGLE (FREE) You can find Google through your mobile browser, but the app is a major time-saver. The voice search function is seamless. Ask it for specific Wikipedia entries, for instance, and it complies. Or just say "Starbucks" and the app uses the phones GPS to find the nearest location. A recent update put the "Goggles" service within the app, so you can snap a photo and let Google search for information on that object. And given Googles emphasis on mobile, the app will continue to improve. SOUNDHOUND ($5) Youve probably heard of Shazam, the app that identifies songs. SoundHound is faster, and it offers a broader range of ancillary features. You can hum a tune into the phone and itll find the song, look up lyrics and run YouTube videos of song performances. The $5 version lets you identify an unlimited number of songs. Users of the free version get five tags monthly. HIPSTAMATIC ($2) Scores of photography titles are in the App Store. Many are terrific, but not one matches Hipstamatics blend of simplicity, serendipity and art. At heart, the app is a filter that will unpredictably saturate, blur or discolor your images, among other things. The results are always surprising and often stunning. Add packs of lenses and film effects for $1 apiece. KEYNOTE ($10) Keynote, the powerful presentation application for Mac, has been completely redesigned for iPad. It makes creating a world-class presentation, complete with animated charts and transitions, as simple as touching and tapping. It has everything you need to create amazing presentations, including beautiful Apple-designed themes, custom graphic styles, and stunning animations and effects. Start quickly with a theme and add the slides you need with just a few taps, selecting any of eight slide masters. You can also open a Keynote 09 or Microsoft PowerPoint file.. ANGRY BIRDS ($1) A runaway favorite among the iPhone crowd, the app tests your ability to break down the barricades that protect green pigs. The weapon: flightless birds, launched by catapult. No wonder theyre angry. The game is easy to learn, yet challenging to play, with witty touches throughout. You can try a limited free version, but if you do, good luck resisting the paid version, with more than 800 possible scenes. STAR WALK ($3) Point your phone toward the heavens and this app identifies all you see constellations, planets, individual stars in brilliant clarity. If you pivot in another direction, the app follows. Its an astonishing app thats great to pull out during dinner parties, beach walks or sleepless nights in bed. You neednt have a clear view of the sky to experience the starry night. QUICKOFFICE MOBILE SUITE ($5) The next time someone e-mails you a Word, Excel or Powerpoint document, Quickoffice will open it and allow you to make quick edits from your iPhone. (Otherwise, you can open, but not edit, Microsoft Office files.) You can also create documents with the app, but it is far less useful for that purpose. Rather, Quickoffice offers a way to complete small work tasks easily while you are on the move. GARAGEBAND ($5) GarageBand turns your iPad into a collection of Touch Instruments and a full-featured recording studio so you can make music anywhere you go. Use Multi-Touch gestures to play pianos, organs, guitars, drums, and basses on your iPad. They sound and play like their counterparts, but let you do things you could never do on a real instrument. Enjoy a full range of Smart Instruments that make you sound like a pro even if youve never played a note before. Plug an electric guitar into your iPad and play through classic amps and stompbox effects. Use the built-in microphone or a guitar to record, or capture any performance. Then mix up to eight tracks to create a song you can share..
