Offline science-trivia app
A 100% offline Android app for an educational title, with hundreds of life-science curiosities organized by section and a timed true/false quiz — for a publisher already running the app in production.
Problem
The material needed a mobile version that worked without internet anywhere, with all content and images already on the device, and that turned reading into something more interactive than plain text.
Solution
A Flutter app bundles 250 curiosities and their images into the installer itself, with no network permission at all: browsing across 17 sections, search and favorites (persisted with shared_preferences) all work the same with the device in airplane mode. A 10-question timed true/false quiz with a streak bonus, sound (audioplayers) and a best-score record adds a game layer on top of the content, with Provider managing each screen's state.
