A touch typing tutor.
It provides various kinds of lessons. The original lessons are from "typist" by D. J. Penney, 1991.

In Typist Version 3.0.0, dark mode for macOS 10.14 Mojave is added. Some functions are also added for Japanese exercises. Besides, a few errors in the text were corrected.

Version 3.0.0 can't run on Yosemite

I confirmed that Version 3.0.0 can not be executed in Yosemite (maybe, in other earlier OSes, too). I plan to prepare a modified version in a hurry.

If you want older version (2.4.0), you can download the version without the function of iCloud here.
First, delete existing Typist, and then install the package.

Privacy Policy
  Typist doesn't acquire personal information. (Except for the information sharing function of users that Apple provides as functions of iCloud)



 The Latest Version: 0.7.1 (Feb. 2018)
OS Versions: 10.10 Yosemite or Later.

AnswerSheetDIY is an application that reads the presence or absence of marks from bubble answer sheet images and can save the result as CSV or TSV format data. You can use the data for some spreadsheet applications.
When you want to do quizzes in some lesson or want to take a questionnaire, you can easily get the result without special card readers or special kind of sheets.
AnswerSheetDIY provides only two functions:
  (1) predefining the information on the bubble positions of the document, and
  (2) judging the presence or absence of the mark on the bubbles and outputting it as data.
Therefore, you have to prepare the original of the answer sheet by yourself.
A device dedicated to bubble answer sheets is unnecessary, but a printer and a scanner with an automatic document feeder are necessary.
A detailed manual is included and is available via Help.

Since it has no aggregation function, please do it by yourself by script language or spreadsheet.
