I think you may need to update your app. Vermont used to be the only state with constitutional carry but now several more states have eliminated licensing requirements,
From: http://www.gunlaws.com/ConstitutionalCarryIndex.htm
Vermont has had Constitutional Carry since the nation’s founding in 1791 —they never enacted any law banning the right to discreetly bear arms.
Montana enacted Constitutional Carry in 1991, for all areas outside city limits (99.4% of the state), and is working on the rest.
Alaska enacted Constitutional Carry in 2003.
Texas enacted Constitutional Carry “light” in 2007 as the “Motorist Protection Act,” freeing people to carry in their vehicles, and to and from their vehicles and their homes, land or business.
Arizona got full Constitutional Carry in 2010,and the sky has not fallen, despite desperate fears to the contrary.
Wyoming enacted Constitutional Carry for residents in 2011.
Arkansas passed HB1700 (Act 746) on August 16, 2013 to get Constitutional Carry.
Kansas pushed Constitutional Carry through with widespread support in 2015.
West Virginia had to override the Governor’s veto to pass the law in early March 2016.
Idaho pushed it through and got it signed later in March 2016.
Mississippi succeeded in enacting Consitutional Carry in April 2016.
Looks like the Ohio reciprocity map does need to be fixed in the app - the *list* of recognized states does include Vermont. Feedback e-mail sent.
