Does a concrete caption-review third frame improve task comprehension and qualified acquisition?
- Audience
- Eligible US English iPhone default-page visitors, with research among people creating spoken social clips and captioned personal videos.
- Control
- The captured editor, transition and multilingual-caption sequence after verifying any retained language and access claims.
- Treatment
- Replace only frame three with a genuine caption correction and timing example. Keep the first two stills, metadata and offer unchanged.
- Method
- Validate the selected spoken clip and language in the current app, then run comprehension research and eligible randomized App Store product page optimization.
- Primary measure
- Platform-reported download conversion for eligible randomized visitors.
- Guardrails
- Visitors should distinguish transcription from translation and drafts from backed-up source media. Check expected editing access and export conditions; do not infer retention from acquisition alone.
- Decision rule
- Predefine useful effect, sample requirement and analysis timing from baseline traffic. Retain control if inconclusive or if a lift depends on mistaken accuracy, language or storage expectations.
- What could muddy the result
- Creator trends, platform editing changes, paid offers, language mix and major editor updates may alter conversion.
