We’ve got iPhone apps on the brain (and in the mag) this month, and here’s another to add to our obsession. The classic kids’ magazine Highlights for Children is taking its popular feature, the Hidden Pictures Game, digital. Much like the original game, kids search for images embedded within illustrations. Unlike the analog version, however, the black-and-white pictures turn to color as each hidden item is uncovered, and a “hint” feature nudges players in the right direction. $1.99 buys a pack of eight puzzles. Let the obsession begin!

It’s a Saturday afternoon. You’ve just attended one of the many events happening around the city with your crew—which you undoubtedly got wind of via Time Out Kids—when the inevitable question arises: What’s next? If you’re facing such a quandary, the new iPhone app iKidNY has you covered. It’s premise is simple: To help NYC parents find what they’re looking for—be it a changing table, a restaurant or an activity. iKidNY can be purchased on iTunes for $2.99. Let us know what you think of it.

Halloween’s still a couple of weeks away, but your tech-savvy kids can get a jump on the creepy and the kooky. A new iPhone app called R.L. Stine’s Haunted House of Sound, which the mega-bestselling “Goosebumps” scribe emailed us personally about (really!), lets you insert more than 150 funny, gross or scary noises into five of the author’s spine-tingling stories. So it’s like “Mad Libs,” but with menacing growls and freaky tunes instead of  non-sequitur nouns and verbs. Bonus: You’ll find reviews of other new iPhone apps for restless fingers in the November issue of Time Out Kids.
