LessonSync

Core Functionality

• Drag‑and‑Drop Lesson Builder – Teachers can add text blocks, images, videos, quizzes, and external resources to a timeline with simple touch gestures.
• Live Student Check‑Ins – Students tap an icon during class to confirm understanding; the teacher sees a live bar graph of responses.
• Cross‑Device Sync – Plans saved in the cloud are instantly available on tablets, phones, or laptops.

Problem It Solves

Teachers often juggle multiple lesson plans across paper, PowerPoint, and spreadsheets. Updating a single version becomes cumbersome, especially when teaching remotely or in hybrid settings. LessonSync consolidates planning into one intuitive interface, eliminates version drift, and gives instant insight into student engagement without the need for additional hardware.

Technical Requirements

• React Native – Cross‑platform mobile UI with native performance.
• Expo SDK (optional) – Simplifies setup and OTA updates.
• Firebase Firestore & Auth – Real‑time database for sync and secure login.
• React Navigation – Easy navigation between screens.

Monetization Strategy

• Freemium Model – Basic lesson builder and student check‑in are free. Premium tier unlocks advanced analytics, template library, and custom branding.
• School Licenses – Bulk subscriptions with single sign‑on support for districts.
• In‑App Purchases – Students can buy optional quiz packs or extra storage.

Implementation Approach

1. Set up a new React Native project with Expo.
2. Create authentication screens using Firebase Auth.
3. Design the drag‑and‑drop builder: use react-native-draggable-flatlist for ordering blocks.
4. Store lesson data in Firestore; implement listeners for real‑time updates.
5. Build a student check‑in widget that writes responses to Firestore and displays aggregated results.
6. Add navigation, styling, and basic offline support.
7. Test on iOS and Android emulators, then publish beta builds via Expo.

Potential Challenges

• Drag‑and‑Drop UX – Ensuring smooth gestures on both phones and tablets may require custom touch handling.
• Real‑Time Latency – Large classes could cause Firestore write spikes; use batched writes or debounce updates.

Future Expansion

• AI‑Powered Content Suggestions – Generate lesson outlines from a topic keyword.
• Gamified Student Interaction – Badges and leaderboards for participation.
• Analytics Dashboard – Historical performance trends across subjects.
• Integration with LMSs – Export plans to Google Classroom, Canvas, or Schoology.
