Book Bounce

Marketing Website (bedtimebookhelper.com)

Released on iOS and Android

0.4 Testflight 3/3/2026

One Saturday night, after asking my wife what books to read to our son for the 30 (days in a month) * 2.5 (months we’ve been reading bed time stories to our son) time, we decided a book rotation was necessary.

Thus, this book and reading tracking was born. I build this over a week with the heavy use of AI. On top of preventing reading the same book too many times, I wanted it to be a way to track our “1000 books before kindergarten” goal.

It has a Tinder-esque book selection UX, book likes and dislikes, and, consequently, a obviously algorithm for what to read tonight.

Users are able to add books to their library

Manually
- Take a picture of the cover, input title and author
Via Search
- Search via title or author for OpenLibrary entries
Barcode scan
- Point your phone at a view finder and this app will search the ISBN on OpenLibrary
- Great for bulk additions
