User Guide


This user guide for Asthma Logbook X describes its features and how to use them, and is recommended reading for all users before using the software.

Special Notices


It is strongly recommended that you regularly backup the application's preferences file com.Nesfield.AsthmaLogbookX.plist located in your Preferences folder within the Library folder of your login account; this file holds all of the logbook data.

See the Technical Notes for more information on how the data is stored.

For users migrating to a new localised language version of Asthma Logbook X:

The exisiting logbook data can be used with the localised language version. However, the time 'Period', e.g. 'Morning', will remain in the original language. A new period can be set by editing an event and clicking the black diamond to the right of the 'Period' drop-down list, this automatically selects the correct period for the recorded time.

If a lot of events have to updated the quickest method is to:
  1. select all the events and export them to a data file
  2. delete all events
  3. import the data file
This will set 'Period' to the new language during the import step.

In case there are any errors during usage: see the Technical Notes page.
