My Android Apps - MIT App Inventor
The App Inventor is free and regularly updated, it's a block-based tool that allows you to create apps very easily and quickly. It's a good way to get into app creation for starters as it doesn't require lots of programming knowledge and takes care of many things for you like screen layout on different hardware. I'm going to start off this page with my currently available apps but I will expand and show other work in progress as and when I get the time.

This was the first app that I released for Android phones and is an simple app that simulates rolling up to 18 six sided dice. It rolls the dice based on either shaking the phone or pressing a button and shows the sum, average and distribution of the rolls.

This is a complete app although is a very simple one that could be expanded. I chose this as my first app to release due to it's simplicity and ease of programming but also that it could be useful for people that are avid roleplayers that may may need access to dice without having to carry lots of them around.
Given more time this could be expanded further to include other types of dice and more information on the roll but this will have to come later.

This app demonstrates a statistical problem regarding choosing a prize and being offered a swap based on further information that is named after a gameshow host. It counts how many times you have played the game and won/lost plus it splits these into how many times you stuck with your original prize and how many times you swapped.

This is a simple app/game that probably won't be updated in any large way. I enjoy maths and statistics and this app highlights a problem that many people don't always get right, the computational outputs from this verify the real answer that is often disputed.
The question is often posed as: "Consider you are on a gameshow and you have to pick one of three doors. Behind one door is the jackpot and there is nothing behind the other two. You choose a door but before you are given the prize that you have won the host of the gameshow opens one of the other doors and shows you that is nothing behind it. He then says do you want to keep your original door or swap to the other unopened one?"
Often it is assumed that sticking or swapping has no effect on the chance of you winning the jackpot but, providing this is a fair game and not a magic trick, swapping actually doubles your chance of winning. Your original choice was to pick one door out of three, so had a 1/3 chance of getting the jackpot, the host does not change this, even though you've seen one of the losing doors opened your chance of winning is still 1/3. You know that of the two doors that you haven't picked one of them definitely has nothing behind it (there is at most one jackpot) and the other one either has nothing or the jackpot. If the door that you have chosen is the jackpot door then the other two doors have nothing (this is a 1/3 chance), and if the door that you have picked has nothing then the other two doors are nothing and the jackpot (this is a 2/3 chance of happening). The host showing a door with nothing behind it doesn't change the fact that the two you didn't pick have a 2/3 chance of containing the jackpot so you really should swap.
