1. iHandy Carpenter
Five carpenter’s tools in a single application mean less sifting through an old toolbox to hang a picture. A digital plumb bob tells you if your walls are straight, while a bubble level helps keep things straight. Coolest feature: a digital ruler that measures items larger than your iPhone by using the mobile’s touch screen. Use the digital protractor when designing D.I.Y. pieces; when you’re done, pull out the surface level to make sure the desk you just built is on the straight and narrow. (For iPhone; $1.99)
2. Locavore
Why it’s cool: Eating local is smart for you and the environment. This app shows you the availability of 234 fruits and vegetables at any time of year and where to find them. Features include: detecting what U.S. state you’re in, local food in season now and what’s available soon, farmer’s markets near you, links to Wikipedia and Epicurious (with recipes) and app updates on Twitter. Updates were cosmetic fix and bug that caused crashes (eek) for some California locations.

5. Leaf Doctor
The Leaf Doctor performs quantitative assessments for plant diseases on plant organs such as leaves. Users collect or submit photographs of diseased plant organs and calculate the percentage of diseased tissue. Through a user’s touching of the device screen, the algorithm employs user-specified values for up to eight colors of healthy tissues in the photograph. The color of each pixel is then evaluated for its distance from the healthy colors and assigned a status of either healthy or diseased. Users may slide a threshold bar until satisfied that diseased tissues are represented accurately before the percentage calculation. The assessment data and photographs may be sent by e-mail to any recipients. Instructions for using the app are provided on the About screen. The Leaf Doctor was produced by the University of Hawaii at Manoa, College of Tropical Agriculture and Human Resources.
