Deep Time Walk is an audio experience unlike any other in the App Store. It tells the story of the Earth from the very beginning and its progress is tied to yours. Simply calibrate the pedometer by entering your height. Then put on some headphones and start walking. Each meter traveled is equal to one million years of time, resulting in a 4.6 kilometer walk. During your walk you’ll learn about key concepts like evolution, plate tectonics, oxygenic photosynthesis, multicellular life, and more. A mobility-assist mode is available for those unable to walk.

Color Query puts you in the know. Just point your iPhone at a wall or other object and snap a photo. Color Query will analyze the photo to determine its name and properties like RGB, CMYK, HSB, and HEX. You’re also able to compare colors to five standard pallets, adjust colors, view variations, and save up to 15 samples.

Uncle Henry is back at it again. This time he needs you and your newly acquired archeology skills to help him track down the final enchanted book. To achieve your goal you’ll have to choose the correct paths, pickup clues, and solve puzzles. A built-in hint system will assist you when you’re stuck, and a dynamic map will ensure you won’t simply go running around in circles.

Tiny Dentist includes a vast number of colorful characters in need of dental help. Your child can scroll through all of the tools at the bottom of the screen and tap on the ones that want to use like an extractor, brush, bleach, x-ray, and braces. They can also snap pictures of their patient during or after the procedure.
