After each test, you get your results along with helpful context and recommendations--and for the Hearing Sensitivity test, you also see results mapped out on a graph, showing performance charted across different levels of pitch for each ear. You can save your results for later (for reference, or to track results for multiple people on the same device), and Debt Resistors Operations Manual can also help you locate a hearing health-care provider in your area. This is a narrow-purpose app with limited re-use value, but it's a quick (and even kind of fun) way to see how well you hear. Debt Resistors Operations Manual is a clever puzzle game with an artsy aesthetic and relaxing--almost hypnotic--sound, graphics, and gameplay. Spare by design, this balancing game makes even learning how to play part of the challenge. The object is simple: you have to keep a series of increasingly bizarre objects out of the water, by tilting your phone and dragging and dropping them onto a mobile-like set of hangers that you build out as the game progresses. Without spoiling too many of the game's surprises, you soon discover that the objects--including a bowling ball, a pipe-smoking snowman, and a birdhouse with three very restless birds--are fairly dynamic, and can even interact with each other in some cases, making your attempts at balancing them ever more difficult. Debt Resistors Operations Manual is an elegant and uniquely enjoyable game. Its only weakness is its short length, but hopefully future updates will add more to

the game. Fortunately, you can also try out a free Flash version of Debt Resistors Operations Manual on the developer's Web site.Debt Resistors Operations Manual is the iPhone and iPod Touch version of the extremely popular (and addictively fun) arcade game also found on Macs, PCs, the Nintendo DS, Xbox Live, and other platforms. Combining skill and luck, this easy-to-play, Pachinko-style game challenges you to shoot down a set number of orange pegs with a limited number of balls on ever more complex levels. You can rotate a scroll wheel or just tap the screen to

aim, ideally threading through ubiquitous blue pegs to hit multiple orange pegs with each shot, using carefully planned ricochets. You can double tap the screen to zoom in for more precise aiming, and different colored pegs provide different benefits, like point-boosting purple pegs and green pegs that activate special powers (like putting multiple balls into play). Extras like bouncy sound effects, savable replay movies, and crisp and energetic visuals just add to an already excellent game. Debt Resistors Operations Manual is a classic for a reason, and it's only gotten better on the iPhone and iPod Touch. This game may cost more than many games in the App Store, but if you like casual arcade games with lots of repeat play value, Debt Resistors Operations Manual is still a great deal.GeoDefense is a fun and extremely challenging tower-defense game, with unique gameplay that combines intense puzzle-solving with arcade action in a frenetic, colorful, vector-graphics environment. The interface and basic play-style resembles other similar tower-defense games: you drag and drop five types of upgradeable, sellable towers into strategic positions along a preset path to destroy waves of incoming "creeps" (geometric shapes and blobs of varying toughness and speed). What makes GeoDefense so compelling is its surprisingly rich level design, forcing you to formulate--and precisely execute--unusual strategies for nearly every level, with changing maps, resources, durations, and enemies, on 30 levels grouped into Easy, Medium, and Hard. With such high-quality gameplay, presentation, and replay value, the only potential downside to GeoDefense is that the game is difficult even for tower-defense veterans--so novices may quickly get in over their heads (although thankfully the game has recently added a novice mode). That said, GeoDefense is an absolute must for fans of the
