Paymentz is an easy and fast to use loan calculator. It can calculate:
* Payment
* Present Value
* Future Value
* Interest Rate
* Term
It can calculate any one of those items given the other four.  It's flexible enough to handle loan payments, investment returns, virtually any "time value of money" scenario.  Paymentz was designed to be as straightforward as possible for quick, handy calculations.

PerCentz Free (v. 1.02)

Fast and Easy Grading for Teachers

PerCentz quickly calculates a percentage score based on the total number of problems and the number right or wrong. It's for teachers who have a lot of worksheets, tests, or quizzes to grade and can't instantly calculate any percentage in their head, which, I think, includes almost all of us! It's designed to be as easy and fast to use as possible.

The free version is ad supported.  The full version has no ads.

MazeWorld Demo (v. 1.2)

(обновлено 2012-05-12)

Find your way through beautiful 3D mazes!  Choose from beginner mazes that you'll finish in less than a minute to very challenging, large mazes.  Collect money along the way to buy powerups and points.  Try for personal best times or (in the full version) overall best times.  There are many different mazes to solve (hundreds in the full version) for hours of fun.

Move around by simply swiping your finger on the screen or using the new Virtual Joystick controller.

Some older devices may have trouble with the high resolution 3D graphics in MazeWorld.  If you have an older device be sure to try this free Demo version before purchasing the full version.

Demo version is limited to beginner, easy, and medium mazes (five of each) and overall best times are not posted.  You can't buy leaderboard points either.  Full version has two more levels (hard and "crazy"!) and 100 mazes per level.  Full version also has no ads.

Permissions:
Internet/network state, to post scores and download additional graphics.
Phone storage, to save files to SD card if available.

G:Thirty (v. 1.04)

It's Game Thirty!

Welcome to the FREE Android app that helps you get people together!

New from J+J Software, G:Thirty (or G:30 as we like to call it) is a unique app that makes it easier than ever before to organize your event, party, pickup game, gig, sale, or whatever. Just enter where, when, and what, and hit Submit! Just like that, it's out there where everybody can find it. No hassle, no logins or passwords, none of the annoying overhead of other services.

Or, are you looking for something to do? Search the G:30 database of nearby activities that others have registered. Make your searches as broad or as specific as you want, and save your favorite searches to run automatically!

BTW if you're wondering about permissions:  Internet, because all the data's on a server; Location, so you don't have to type in where you are all the time, Phone State, because it uses your phone's hardware ID code to identify which activities are yours so you can edit them if you want.  That's all.
