Introduction
App Variables are used to store commonly used parameters or settings in the application. Storing commonly used values in one place eases the migration and maintenance of the application developed. App variables can be retrieved by using the App Variable Hash Variable.
One can make use of the App Variable to store commonly used values in places like Email Tool, Database Update Tool, and so on. Doing so makes it easier to manage setting/configuration changes.

Cautions And Warnings
When importing apps into a new Joget platform, for example from development to production server, do update all the environment values you may have defined; IP addresses, domain name, database connection strings values, etc.
However, if it is an existing app in a production server, do be careful not to change any App variable counters that are link to your form's "ID Generator Fields". This may affect the running numbers in the form's new records.
If you are using the ID Generator Field as "id", meaning it is a primary key value, be careful not to override the App variable value when importing apps: do not click the "Show Advanced Options > Override App Variables" checkbox in Import App screen.
