Free app doesn't allow use for any calendar after 2015 – Week Numbers - LITE Review

The central function of the app is to insert an all day event into your calendar to show the week number. The free version of the app won't allow insertion into a 2016 or later calendar, just 2015. An in-app upgrade to the paid version claims to allow use in newer calendars, but the free version is useless after Dec 31 2015.
