Welcome to dotappdevelopers.com!
See below my list of current published apps. Below these you can access the .apk files for my old apps - the ones I have taken off the market because they were not receiving any attention.
CAQ is my Android app which lets you create your own quiz - and then retake it as many times as you want. The CAQ FAQ can be found here
The PC version can be found here
This is the application that unlocks the full version features for CAQ. For the installation process see here. This applications page on Google Play can be found here. Finally, you can see a list of unlocked features here.
Cold War Quiz is very similar to Spanish Quiz in terms of it's layout and features. Cold War Quiz focuses exclusively on the Cold War tensions between 1945 and 1990. Cold War quiz has approximately 250 questions as of the moment - but I am always open to suggestions for more questions to be added. For more information see the Cold War Quiz page.
This is a simple app that has taken a 5000 word long list of common Spanish vocabulary words from the web, and asks you them in a random order. You can find it's page on Google Play here
As of the moment, I have only taken one application off the market. This is a simple counter application which can be downloaded from here. If you wish to have the source code for this application, I can send it to you via email.(see the contact page). Please do not report bugs for this application -- it is no longer under any form of development and any problems will have to be ignored.
