Google Catalogs, MiniMash, The World and MoreCasey Chan8/19/11 6:00pmFiled to: Ipad apps of the weekappsIpadapps0EditPromoteShare to KinjaToggle Conversation toolsGo to permalink The World by National Geographic: It's a 'maps' app in the sense that the bulk of what you're looking at is maps. But it's also a spinning globe app that allows you to twirl around our little blue planet to your heart's desire (rich people: pick your next vacation!), a photos app that shows you astonishingly gorgeous pictures of places around the world (hey Algeria, you are booootiful) and a Flag book that shows you all the flags of countries around the world. The idea is to let you poke, prod and yes, spin the world around however you want. $4 Google Catalogs: Google Catalogs has signed up some younger retailers whose products can be browsed easily in the app, such as Urban Outfitters, Sephora, Macy's, Nordstrom, Williams-Sonoma and Pottery Barn. The app seems like a smart way to browse for items of interest, whether it be a specific search (such as a red jacket), or just by category. Free MiniMash: It takes what songs you have your iDevice, analyzes them, and lets you mash them together quick fast. Only the layout is way stripped down; it looks rather like if wanted to do a set on a Super Nintendo. All the heavy lifting is done in the background-tempo and pitch matching-so that you can create smooth transitions and mixes for most of what you throw at it. You can't scratch, but you do have some of the tools to do more creative, powerful things with your remixes. $2 TableDrum: TableDrum is a drumming app that lets you tap out beats without touching your iOS device. Instead of tapping your screen, you tap an object around you and the app will respond with a drum beat. The developers describe it as an augmented audio application that lets you sync the sound of an external object to a drumbeat. You can tap your finger, slam a door or bang some cans and sync these sounds to the app. $4 Hitchhiker's Guide to the Galaxy: It won't be out until early Fall but the app sounds amazing. It's basically going to be an interactive edition of the guide. Users can "learn all about the importance of towels, vogons, Milliways, the Babel Fish, a Pan Galactic Gargle Blaster, how to survive in space, and more". Helo TC: It's a real life helicopter (toy, of course) that can be controlled by your iOS device. You plug in a "flight deck" which is a headphone jack adapter that turns actions into infrared signals for the Helo TC to read. You can either use a virtual joystick to maneuver the Helo or control it by tilting your iPad forward, backward and side to side. The app is free but the helicopter costs 50 bucks. You can keep up with Casey Chan, the author of this post, on Twitter or Facebook.
