My mobile app has a screen which shows Emergency contacts for that user. Contacts can be 1 or more than 1. What is correct standard or practice to show screen title - Contact/s OR Contact(s).
The Gregg Reference Manual recognises plural endings in parentheses as being the defacto way of showing conditional plurals.
i.e. Contact(s) rather than Contact/s.
However, in your case there seems to be no benefit to putting the plural ending in parentheses, so simply using Contacts would have the same effect and be more readable.
