If you have complex expressions or formulas, you may want to calculate a value and then store the result in a field on the app. If the app field has no other purpose other than storing a value in this way, then it is called a 'helper' field.
There are a couple of ways you can use helper fields:
•Put them on a special page on the app that only contains helper fields and is never seen by app users.
•Use them on a regular page but hide it using a Set State behavior command or by changing its State property to Hidden.
