Expo
Worth it
Confidence: Medium
If you're building a React Native app, buy it . it's the de facto standard and the core is free.

Comparison
Expo vs Flutter
Expo lands on Worth it, and Flutter lands on Depends.
Flutter
Depends
Confidence: Medium
Use Flutter if you have (or will hire) developers and want one free codebase for iOS, Android, web and desktop.
| Compare | Expo | Flutter |
|---|---|---|
| Verdict | Worth it | Depends |
| Best for | React Native app teams | Startups shipping one app to iOS and Android |
| Who it's not for | Web-only or backend projects . no mobile app, no reason | Non-coders wanting an app . learn a no-code tool instead |
| Privacy | Past account-takeover flaws (2023) were remediated; newer CVEs hit optional modules; a security & compliance page is published.⁹ | One patched SDK path-traversal flaw (CVE-2026-27704, patched Feb 2026); no open critical issues found in sources reviewed. |
| Support quality | Strong community; billing-support complaints exist | No support-quality evidence in sources |
| Public sentiment | Reddit and app-store feedback skew positive . many treat Expo as the default way to build React Native apps . with occasional gripes about EAS pricing and a security history.⁵ | Reviews are largely positive . users praise the single-codebase workflow . but long-term Reddit threads flag scaling and ecosystem gripes. |
| Biggest gotcha | Billing trap: one user charged $158 after canceling; says support emails went unanswered.⁷ | Free SDK, expensive app: even simple Flutter apps carry real development price tags |
Pick Expo when
- React Native app teams
- Solo devs shipping iOS + Android fast
- Startups without mobile CI infrastructure
- Teams wanting OTA updates
When Expo is not a fit
- Web-only or backend projects . no mobile app, no reason
- Native-first teams needing heavy custom Swift/Kotlin from day one
- Buyers expecting responsive billing support (see cancellation complaint)
- Flutter or non-React-Native stacks
Pick Flutter when
- Startups shipping one app to iOS and Android
- Teams with design-heavy custom UIs
- Budget-conscious MVPs with in-house devs
- Dart-comfortable engineering teams
When Flutter is not a fit
- Non-coders wanting an app . learn a no-code tool instead
- Simple one-screen apps . templates are cheaper than a framework
- Teams needing deep native Swift/Kotlin features
- Web-first products . Flutter web support is contested
