"Lo que fue y no es..." is an iPhone app designed by developer Alex Mendez, falling under the Education & Reference category with a focus on Books. The app presents a real, sad, and intense love story that many couples might have experienced. It delves into a fate that is unchangeable once written, capturing the essence of what once was but is no longer.

The app offers an emotional narrative that may resonate with those who have gone through unfulfilled love, evoking nostalgic memories and potentially bringing tears to the eyes. Alongside the story, users can enjoy two engaging games: one to assemble the puzzle of the book cover and another to search for words from the story.
