I had a blast browsing through this full-color, 228-page book about the very best iPhone applications. I only knew about 25% of the titles recommended by author Josh Clark, who tested thousand of apps to pick his 200 favorite work and leisure related titles. Some of the apps are free (like TED, which lets you watch those amazing TED talks on your iPhone, and Mint, a personal finance snapshot application that pulls your data from your Mint.com account). Others cost money (like SoundCurtain, an ambient noise generator for $3.99, and Print&Share, which costs $6.99 and lets you print things on your iPhone to a printer).

When nature calls, it's SitOrSquat to the rescue. The database of public restrooms steers you to the closest porcelain oasis, including photos and ratings from a network of concerned citizens. That includes you: Update listings with photos, store hours, and ratings, or add new toilets as you explore your town's powder rooms. A blog of toilet humor provides bathroom reading, too. It's a full-service porta-potty for your mobile phone.
RESTROOM RADAR: SitOrSquat's map shows you the closest points of relief. Green and red icons indicate open and closed businesses (yellow means the database doesn't have that info). Select a business to see complete details, including photos, comments, and whether the facilities are clean ("sit") or dirty ("squat").
PILGRIM'S PROGRESS: The Search screen shows results in list view, including photos, ratings and distance from your current location. Type a new location in the search box to find restrooms for another place, or filter results for cleanliness, business type, or a remarkable number of "features" (changing tables, handicap access, seat covers).
