Define
If you do a lot of reading, you’re learning English, or you just have a curious mind, Define is the perfect addition to your Android device. It’s an offline, device-wide word lookup tool that provides definitions, synonyms and different usages of any copied word through an unobtrusive pop-up window or notification. There are a choice of three dictionaries: Livio, Wordnet and Urban Dictionary, with the latter only working when you’re connected to the internet.
Khan Academy
Khan Academy began producing free and openly available videos and learning resources in 2006. They mostly cover math, physics and science, but offer limited coverage of other subjects, as well. All of Khan Academy's material is freely available on YouTube, but the newly launched Android app offers a quick and simple way to navigate and access its material, of which there is loads. It has more than 10,000 videos, as well as in-depth articles in fields such as arithmetic, algebra, geometry, trigonometry, statistics, calculus, biology, chemistry and physics. We highly recommend spending some time exploring and an afternoon or two learning with Khan Academy. It's free, accessible and fun!
Accomplish
There are plenty of scheduling and productivity apps on the market, but Accomplish's interface is clean, elegant and intuitive. It keeps things as simple as they should be, so you can organize your tasks and set reminders without fuss. You can add tasks, change their colors and then drag them into a day planner, where you can stretch or shrink the box to adjust the length of time you want to spend on the task. Accomplish also syncs with your Google Calendar, and is the most intuitive scheduler we've seen here at AndroidPIT. If you want a simple, pretty way to organize your day, this is it.

Bump
Bump was one of the first apps that blew everyone's minds. As long as you had two smartphones with Bump installed, you could instantly share contact information. Nowadays, you can also share photos, social network connections, and more. Although the music sharing feature is gone, Bump is still a suprisingly useful app to keep around if you're the type that needs to quickly trade contact information or photos with people.
