The Onboarding Trap Every Mobile Team Faces
You launch your app. Users sign up. Then 80% drop off during onboarding. You know exactly what to fix, but...
2-Week App Store Delays
Every onboarding tweak requires a full app submission. By the time it's approved, you've lost thousands of users.
Can't A/B Test
Want to test if a video or text works better? You're stuck guessing. No data, no optimization, just hope.
One-Size-Fits-All
Enterprise users and free users see the same onboarding. You can't personalize without hardcoding dozens of versions.
Expensive Dev Time
Your engineers spend days building onboarding flows instead of core features. Then more days updating them.
