After a couple of months of development the new version of Times Tables for the iPhone and iPod Touch is now available in the app store. This version contains a lot of changes and new additions and has things that will be of interest to children and also to parents.
For the children there are highscores, sound effects, quick quizes, and perhaps more importantly a competition mode. For the parents there are multiple levels of difficulty for each of the tables, progression tracking of the tables and questions, and there are different types of quizes that provide timed and non-timed tests.
For more information see the Times Tables page here.
A minor update to Learn Time for the iPhone and iPod Touch is now available in the app store. In the previous version the 5th level was missing from the home screen and so the only way to get to it was to finish the 4th level first. This version also adds email and website links.
In the next version I plan on adding sound effects and hopefully also a different type of quiz.
The latest version of Roman Numerals has been approved and should be available on the app store. This version adds a must requested method for clearing the inputted numbers in one go and extends the Arabic to Roman numerals converter to generate larger numbers in an archaic format, for example, 1661 can be represented as (I) I) CLXI.
To use this new format just select the 2002 -> MMII tab and press the bottom left button with the ((I)) I)) symbol.
A new version of Learn Time for the iPhone and iPod Touch is available on the app store. This version adds more animations and also allows the starting level to be chosen. New levels are made available as the child progresses so that the harder levels are only available once the simpler questions have been answered correctly. More details can be found here.
Update: this version is now available. See this post for more details.
As promised, I am working on a new version of Roman Numerals. My main aims for this version are:
support for large numbers;
easy cleaning of inputted year.
There are multiple ways of writing larger numbers and I hope to be able to incorporate these into the future versions of the Roman Numerals program. For now I am focusing on the use of brackets (they are the letter C and the reverse letter C) to multiply the numbers, so that (I) is equivalent to 1,000, ((I)) is equivalent to 10,000, I)) is equivalent to 5,000, etc.
The following screenshots show some examples of these:
