iPhone stopwatch for psychological assessment.

PsyTimer is an advanced stopwatch for iPhone that can be used for psychological assessments and similar timing tasks. It has been designed by an experienced neuropsychologist.

The elapsed time will feature on a digital display as well as on an analogue clock. This makes it easy to collect information during testing. All functions are easy to access, and a big Start-Stop button is located at the bottom of the display, making it easy to reach:

The iPhone will not dim or turn off as long as the stopwatch is active.

You may choose to have the main digital display to show the total number of seconds elapsed rather than minutes and seconds. The smaller digital display within the analogue clock face shows the other format (minutes and seconds if the larger display shows total seconds):

You can choose to have a time limit. A progress bar wil display the elapsed time if a time limit is chosen, so it is easy to check when time is almost up. The switches for Time limit, Repeat and Alarm sound is conveniently located on the primary display:

If you choose the repeat function, the stopwatch will be cycling an interval. This is convenient when using a test like the "d2" concentration test, where the assessor has to give a prompt every 20 seconds. A cycle count is displayed.

The digital display will change colour when the time limit has been reached. You can also choose for a sound signal to emit at this point (optional):

You will probably want to put your iPhone in "Flight Mode" when using the stopwatch in order to avoid calls, mails etc. during testing.

Thouching the small "i" button on the main display will reveal the options display. Here you may choose 1) whether to show total seconds on the larger digital stopwatch display, and 2) the time limits for the buttons:

When you select the time limits for the buttons, two rows of buttons are shown. The row with a selected button is the row shown on the stopwatch. The stopwatch saves the values for both rows. Thus, you may keep two sets of time limits fitting two different test batteries. During testing you may toggle quickly between the two sets of time limits using the A-B button located just below the row of time limit buttons (new in version 1.4).

PsyTimer is available on iTunes AppStore ($4.99). Please click here (requires iTunes).
