The four market days that make up "ofu izu" (one week) in Igbo traditional calendar system are very significant in Igbo communities especially when fixing traditional events and cultural ceremonies. Any Calendar that can assist to determine the Igbo Market Day of a future date becomes handy and an important planning tool. To add fun to using this app, previous versions were developed to resemble the wall calendars we keep in our homes by displaying Igbo-themed beautiful photos.

Most notably, Igbo Riddles come in form of a game where users are challenged to provide answers to Igbo riddles; thereby propagating the Igbo Language and Culture.
