OTA updates use cases

• Bug hot fixes: don't wait App Store review (1-3 days)
• A/B testing features: different channels
• Configuration tweaks: no native update
• Content updates: copies, assets

OTA limitations

• Native code changes: require rebuild + store submit
• Bundle size: OTA limit (mobile data download)
• App Store guidelines: don't change app purpose

Africa use cases

• RN startups: Expo simplifies distribution
• Internal tools: economical EAS Build
• Critical OTAs: fast security fixes
• Multi-environment: preview / staging / prod profiles

Notable adoption

• Brex: business banking
• Coinbase: (partial)
• Discord: (partial)
• Burger King: ordering app
• Coursera: mobile learning
• Klarna: commerce

2026 alternatives

• Bare React Native: full control but heavy
• Microsoft App Center: post-Microsoft 2024 layoffs decline
• Codemagic: primarily Flutter + RN
• Fastlane: CI/CD scripts but setup-heavy
• Bitrise: mobile CI/CD

FAQ

Q: Expo limit custom native?

A: No more since Expo Modules 2022+. 99% cases covered. Bare workflow possible if really custom.

Q: OTA legal?

A: Yes since Apple 2014 + Google. But not for changing app purpose (rejection if abused).

Q: Total Expo cost Africa startup?

A: Free tier sufficient MVP. Production $99/mo acceptable from traction. Build expensive self-host alternatives.

Conclusion

2026 Expo: React Native mobile dev de facto standard. SDK 50+ + EAS Build/Submit/Update = complete production stack. Critical OTA updates for rapid iteration. For Africa startups, Expo Free tier sufficient MVP + Production $99/mo economical. Massively reduces time-to-market vs bare RN setup. Future-proof React Native ecosystem investment.
