I'm building a mobile app and want to test onboarding flows, what platform fits

If you want to test onboarding flows for a mobile app, the best fit is usually a mobile A/B testing or feature flag platform with screen/flow experimentation support.

Good platform types to look at

• Product experimentation platforms: for A/B testing onboarding steps, copy, button order, paywalls, etc.
• Feature flag platforms: for rolling out onboarding variants safely and targeting user segments.
• Analytics + experimentation suites: if you want to measure funnel completion, retention, and conversion in one place.

Popular options

• Firebase Remote Config + A/B Testing

  • Good if you already use Firebase
  • Easy for Android/iOS onboarding experiments
  • Works well for simple variants and remote rollout

• Optimizely

  • Strong experimentation tooling
  • Good for more advanced onboarding tests and segmentation

• LaunchDarkly

  • Best if you want feature flags plus targeting and gradual rollout
  • Often used with custom analytics for measuring onboarding success

• Amplitude Experiment

  • Strong if your onboarding testing is tightly tied to product analytics
  • Useful for funnel-based experimentation

• Braze / Clevertap / OneSignal

  • Better if your onboarding is mostly driven by in-app messaging, push, email, and segmentation
  • Less pure experimentation, more lifecycle onboarding optimization

If you mean “test the flow internally before launch”

Then consider:

• Firebase Test Lab
• Appium
• Detox or Maestro These are for automated UI testing, not A/B experimentation.

Quick recommendation

• Simple onboarding A/B tests: Firebase Remote Config + A/B Testing
• Serious experimentation program: Optimizely or Amplitude Experiment
• Safe rollout with flags: LaunchDarkly

If you tell me:

1. iOS, Android, or both
2. whether you want A/B testing or QA automation
3. your analytics stack
   I can recommend the best exact platform.
