I created this because I wanted to read books more (and for free!) but can not choose the right one to read.
There are over 60,000 free e-books on Project Gutenberg, but it's a bit hard to choose the right one from such many books.
With BungoSearch, you can search books by the estimated time to read.
If you only have 5 minutes of spare time, just select "5mins" and you'll find the great short stories :)
All the books are ordered by the popularity in Project Gutenberg, so just pick the books from the top page of the search result, and you'll never be disappointed ;)
Hope this helps your reading life!
