Importar libros es un lio. La app no reconoce bien mis archivos PDF. Los subo y a veces desaparecen. HORRIBLE. La idea de predecir cosas antes de leer esta bien pero si no puedo ni meter mis libros para que sirve. Muy frustrante.

JewelsForecast is a mobile reading companion built around a single disciplined idea: write down what you expect from a book before you read it, then return to measure how accurate your thinking actually was. It's aimed at readers who want to understand not just what a text says, but how their own mind shapes the way they receive it. The app stores your library locally, guides sessions step by step, and keeps a record of completed thinking exercises over time. Inside you'll find a structured workflow, a personal book library, and settings tuned for extended reading sessions.
Inside the App
How It Works
JewelsForecast approaches reading as an exercise in self-examination. Before opening a book, users write predictions — hypotheses about what the text will argue, feel like, or reveal — and attach a confidence value to each one. After reading, those predictions are revisited and scored against the actual content. The point is not to get the plot right. The point is to notice where your assumptions were confident but wrong, or hesitant but accurate, and to ask why.
How a session works
A session runs across multiple steps — the interface shows progress as "Step 1 of 12" — and begins by attaching a book from your library. Books are stored locally on the device; the app supports TXT and PDF files, with EPUB metadata only. Each title in the library carries tags and a short icon, keeping the list scannable. From the book details screen, users can read an annotation and a first-pages preview before committing to a session. Sessions are logged and counted, and a streak tracker records consecutive days of activity.
What the interface looks like
The app runs on a dark theme with white text and orange accent elements throughout — progress indicators, active navigation tabs, toggle controls, and primary action buttons all share the same warm orange. Navigation is handled by a five-tab bar at the bottom: Home, Library, Insights, Archive, and Settings. The Settings screen lets users adjust font scale, toggle haptic feedback, and enable or disable soft sound effects. All data lives in local storage; there is no account system visible in the interface.
A visual parallel worth noting
The app's promotional screenshots place the reading interface against a backdrop borrowed from Joker's Jewels — a slot game built around spinning reels, cyan crystalline gems, golden coins, and a jester character in a red, blue, and yellow hat against a deep purple starfield. The contrast between that world and JewelsForecast is striking: one runs on color, speed, and visual spectacle; the other on deliberate text, structured steps, and measured reflection. The jewel imagery shares a name but almost nothing else with the app it promotes.
One genuine limitation
- The app has no visible screen reader optimizations. For users who rely on assistive technology, interactive elements — buttons, toggles, navigation tabs — may not be reliably announced, and no alternative text descriptions are present for visual content.
- There is no high contrast mode option in settings, which may create readability issues for some users given the dark purple backgrounds used in certain screens.
JewelsForecast is less about what you read and more about auditing the mental habits you bring to reading — a quiet, methodical tool for anyone who suspects their interpretations are shaped by more than the text itself.
