Here is a collection of software I've made. There are no huge applications like Word or Photoshop, but I believe they can improve your work and bring you more fun.

Some of these programs don't have English manuals (I'm sorry my English isn't good enough) but they all have English interfaces and they are based on the standard Mac interface (Human Interface Guideline), so once you start to use these softwares, you can find them very easy to handle/use without any guidance. Please feel free to download and try them.
