I'm Calculator Plus - the perfect calculator for Android. I'm easy to use and beautifully designed to do things better than your phone or handheld calculator ever did.
I'm big, easy to read, and I love saving you time and effort. I remember everything you calculate, and let you review it anytime, making me perfect for shopping, doing homework, balancing checkbooks, or even helping with taxes. And if you need to quit and go do something else, I'll have it all waiting for you when you come back. You'll never need to type the same calculation twice again.
I'm attractive and effective and I make great use of your big, beautiful display:
- I show your calculations in clear, elegant type that's easy to read, with commas just where they should be
- You'll never lose track of where you are in a calculation - I show you exactly what's happening at all times
- I remember everything, so you can take a break, then come back later and pick up where you left off
- You can use backspace anytime to correct a simple mistake, instead of starting over
- Use memory to keep a running total you can actually see
- Swipe memory keys aside if you need more advanced math functions
- My percentage key shows exactly what it did, so you're not left confused
- My intuitive, lovable design makes it simple to do everyday calculations on your phone or tablet

The Google Code page for this game can be found at:
There is a beta version available for download from the project website if you're feeling somewhat adventurous. It will install alongside the market version so you won't lose this one by trying the beta.
Test it out and send any feedback (both good and bad). I'd like to eventually replace this version with the beta when it's completed.
*MIUI and Android 4.0+ users will need to set the Vertical Location to BOTTOM. Otherwise the drawer's bar will be behind the status bar and will not be accessible.
Pulling up/down on the left, middle, or right 1/4 of the status bar or bottom of the screen (depending on your setting) will display all of your installed apps. No need to go back to your homescreen to launch other apps!
It will even work when the status bar is not present (e.g. when an app is running in fullscreen). This may interfere with some games so you may want to stop the service before playing games if it causes problems.
There are settings to choose which apps to shown or hide in the pulldown and also settings to customize the appearance.
**NOTE: Because of a "feature" of the Android OS, the back and home buttons will not close the app drawer if it is opened within 5 seconds after pressing the home key on your device. Just be aware of that so you don't accidentally close apps behind the drawer.
