YeboLearn Mobile: Battle-Tested Worldwide

Executive Summary

Mobile isn't just a feature—it's how 80% of the world accesses YeboLearn. While PowerSchool forces schools to use desktop computers, YeboLearn delivers a complete school management platform that works flawlessly on any device:

Mobile-First Design Philosophy

Design Principles (Worldwide)

1. Emerging Markets Optimization (3G/4G)

• Data-conscious: Lazy loading images, compressed assets, minimal JavaScript
• Offline-first: Service workers cache everything, background sync when online
• Low-bandwidth: Works on 2G/3G (tested in rural Africa, proven in emerging markets)
• Small screens: Optimized for 4-6 inch screens ($50-150 Android phones)
• Battery-efficient: Minimal background processing, efficient rendering
• Storage-aware: Compressed cache, automatic cleanup, <50MB total storage

2. Developed Markets Excellence (Broadband)

• Fast performance: <1 second load times on 4G/5G/broadband
• Rich features: Full HD images, video, real-time collaboration (when bandwidth allows)
• Premium UX: Smooth animations, native-feeling interactions, haptic feedback
• Large screens: Optimized for iPhone Pro, Samsung Galaxy, tablets
• Desktop fallback: Responsive layouts scale beautifully to desktop when needed
• Advanced features: Push notifications, biometric auth, camera integration

3. Universal Design Principles

• Thumb-friendly navigation: Bottom navigation bar, large touch targets (44x44px)
• Single-hand operation: Critical actions within thumb reach
• Gesture support: Swipe, pull-to-refresh, long-press
• No hover states: Touch-first (no desktop hover dependencies)
• Responsive layouts: 320px (small phones) → 768px (tablets) → 1024px+ (desktop)

/* Breakpoints (Mobile-First) */
- Mobile: 320px - 768px (primary design target)
- Tablet: 768px - 1024px (secondary)
- Desktop: 1024px+ (bonus, scales up from mobile)

Mobile UI Components
