I read a lot. I also forget a lot of what I read, which defeats the purpose. A reading log seemed like the obvious fix — except every reading app I tried was either too heavy (social features, shelves, followers) or too light (just a list).
So I built my own. The core feature: after you finish a book, it schedules review prompts at intervals based on the Fibonacci sequence — 1 day, 1 day, 2 days, 3 days, 5 days, 8 days, 13 days. Spaced repetition, golden-ratio style.
The UI is deliberately minimal. A list. A form. A review prompt when it's time. No covers, no stars, no social feed.
