I seemed to have skimmed past this when creating my vault. How can I check what difficulty I am on after creating the vault?

Your vault list will show whether a vault is in Survival Mode or not.

Vault 219 in the screenshot has the "S" poker chip indicating Survival Mode.

As far as i'm aware there is no difficulty option in Fallout Shelter. Simply, the games difficulty slowly increases as you level up your vault dwellers and your vault.
