After a few months of reading to our son we couldn't remember what books we read and when, we realized that our personal library had hotspots, and we were going to need the option for variety when the time came to choose bedtime books.
This app gives my wife and I a rotation for our physical books based on the last time they were read and the frequency setting on each book. It also throws in other children's books on OpenLibrary to read to him. We've found some new favorites from this feature. Reading activity is logged as well. We've used it to track his 1000 Books Before Kindergarten progress.
Supabase stores a pool of OpenLibrary ebooks to randomly suggest to users. OpenLibrary's API is used as a book data source. Everything else stays local to your device.
TLDR: App that helps parents rotate through story books, suggests ebooks on OpenLibrary, tracks reading activity, data stays local.
