Does a clearer AI speaking-practice headline with accurate access wording improve comprehension without reducing qualified conversion?
- Audience
- Eligible US English iPhone default-page visitors, with separate research among people seeking free lessons and speaking practice.
- Control
- The intact current sequence, only after any confirmed access inaccuracy has been corrected consistently.
- Treatment
- Change only the third-frame headline and necessary access label to verified practice wording; keep the first pair, example interface, order and metadata fixed.
- Method
- Verify entitlements and comprehension first, then use eligible App Store product page optimization. This tests the combined wording treatment, not independent effects for each word.
- Primary measure
- Platform-reported download conversion for eligible randomized traffic.
- Guardrails
- Separate research must check whether viewers distinguish free lessons, AI practice and community feedback. Do not infer learning outcomes from installations.
- Decision rule
- Set a useful effect, sample requirement and analysis date from real baseline traffic. Keep control if inconclusive or if access misunderstanding persists.
- What could muddy the result
- Course rollouts, subscription changes, language mix and back-to-school campaigns can alter the result.
