All Android devices contain an accelerometer. Here we use it to implement an enhanced version of a game common 30 or 40 years ago.

In that game there was a ball that had to be maneuvered by tilting the board so that the ball rolled into a pocket on the board. In this version the ball is a smiley face, and the pocket is a revolving shape. 'Pocket' the face by tilting your device to make the face rest over the pocket for three seconds. Just making the ball pass over the pocket will not work! Unlike the original game, each time you succeed, you earn a point, the pocket moves, and you can try again - Earn as many points as you can in two minutes.

Three levels are available. Level one is a bit like the ball is moving through light oil. It takes time both to get it moving and again to slow it down. By level three the slightest tilt will make the ball move rapidly. Just like flying a plane, the trick is to maneuver your phone or tablet GENTLY!

This app has been tested on a Samsung Galaxy Tab. Please let us know how it works on other phones/devices - if it doesn't work well on your device please don't give us a bad review - instead let us know and we will try to fix it.

NB: From v1.1 of the app, the Adobe Flash AIR runtime must be at least v2.6 to work correctly - if you have an earlier version please upgrade it for free from the market.

Compound Interest Calculator (v. 1.5)

This app is free and does not send you a single ad! It doesn't store your IP address or any other information about you whatsoever.

This is a simple but useful compound interest calculator. Enter a principal (initial amount), an annual interest rate, and the number of years you can leave your investment to grow. If you can add an extra amount every year your investment will grow much faster!

Unlike many similar calculators, this one updates immediately as fields are changed - you don't have to press a 'calculate' button to get results.

When used for the first time after installation, you will be asked to select your currency symbol - currently, US dollar, UK pound, and European euro are supported.

This calculator requires the Adobe AIR Android runtime. If it is not already installed on your phone or tablet, you will be prompted to install it the first time you run the app.

From v1.4 the app can be moved to an external SD card conserving internal memory, often in short supply!

v1.5 added an unobtrusive copyright text.

Loan Repayment Calculator (v. 1.5)

This app is free and does not send you a single ad! It doesn't store your IP address or any other information about you whatsoever.

This calculator shows you how long it will take to repay a loan. Enter the initial loan amount, the annual interest rate (APR), and the amount to be repaid each month.

It will also tell you if your proposed monthly repayment will never repay the loan amount (because the interest charged exceeds the repayment).

One difference between this calculator and most others is that it updates immediately a field is changed, ie. you don't need to fill in all fields and then press a 'calculate' button.

The first time you run the app you will be asked to select your preferred currency symbol - currently US dollar, UK pound and European euro are supported.

From v1.2 it also tells you how much interest you will pay on your loan.

From v1.4 the app can be moved to the external SD card to conserve internal memory space.

NB: This app runs on top of the Adobe Android AIR runtime. If not already installed on your device, you will be prompted to install it when you first run this app. Adobe AIR is the standalone version of Adobe Flash Player that serves you rich multimedia content every time you browse the web.
