This android app is essentially a very simple car loan calculator that took me about 2-3 days of my off time on weekdays to develop. The reason why I created this calculator when there are others out there is because so far the ones i’ve seen doesn’t seem to match up and why I say this is because the one I’ve created has these features:

- Simple and straightforward interface
- Allows you to input in the car purchase price, down payment amount, interest rate (decimals allowed) and select the installment months
- Screen is kept ON all the time while the calculator is visible
- Screen orientation is fixed to portrait
- Has an option to clear all the fields and start over again through android’s context menu
- Better looking background (well at least from my personal point of view)

New In v1.1:
- Improved overall layout
- Improved about dialog
- Added share button to context menu
- Fixed some bugs
- Ad-Supported (only when you are connected to internet)

New in v1.2
- Improved overall look
- Added reset button

Please comment on the app whether you like it or not or have some suggestions / issues encountered. Thank you!
