S Planner change clock settings

[Angelica2]

When I started to use S Planner it showed the option am and pm when I was setting an appointment now I have to put everything into the 24th clock format. How do I change it back?

Are all your time prompts displayed that way or only on S Planner? If it's everywhere, it should be on the Time & Date settings of your phone.

What phone do you have? I'm looking at my Note 3 and Note 10.1 2014 and the S Planner still lets me input in the AM/PM format... And I don't see any setting to change that, either.
