Couched Words is an easy way to organise and manage your Book Club.
At it's core it's a simple method to submit your reviews and book ratings to the Club.
But it also handles all the administration of the Book Club too - automated reminders for when Book Club is coming up (SMS and/or Push Notification), maps to the location, discussion points/questions for the current book, comments on the book, comments on the meeting and discussion, book suggestions for future books, create a menu for the meeting (who's bringing what dish), membership management, attendance records etc.
The customer is anyone who is a member of a Book Club. In my small rural township in Australia, there are more than 50 Book Clubs. Book Club members are often well educated and affluent, and a high proportion are owners of smartphones or tablets (iPads and Kindles). These people would pay for an app and/or service which takes the hassle out of organising dates, locations, menus etc. every fortnight or month.
