The fact that there isn't any app that does the same thing doesn't necessarily means that there's an opportunity, on the opposite, it likely means that there is no market for it. Yours it's a niche interest and the app would thus have a niche market, which means you won't make money out of it. If you're okay with it and money isn't what you're looking for, then by any means create your own app.

The fact that it is a niche market doesn't necessarily mean you won't make money out of it. On the contrary if you can work out a good way to monetize it, niche markets can be the most lucrative.

If Amazon allows affiliate links to TV shows/movies, the OP could provide a link to the episode/movie where the quote originates.

Not looking to make any money out of it at the moment! Just something that people can use and appreciate.
