Does a clear alarm-setup third frame improve understanding and qualified acquisition after claim review?
- Audience
- Eligible US English iPhone default-page visitors, with separate research among people seeking an alarm and those seeking a sleep report.
- Control
- The captured connected opening pair and report third frame only after outcome and comparative claims are substantiated or corrected; establish a new baseline if wording changes.
- Treatment
- Keep the approved first two frames together and replace only the third with a verified setup and alarm-confirmation view. Hold metadata and offer constant.
- Method
- Verify the current alarm and recording flow, then use comprehension research and eligible randomized App Store product page optimization. This evaluates communication, not clinical accuracy, alarm reliability or sleep improvement.
- Primary measure
- Platform-reported download conversion for eligible randomized traffic.
- Guardrails
- Participants must understand alarm state, recording context and the limits of report interpretation. Reject diagnostic or guaranteed-outcome expectations; assess operational reliability separately with appropriate product testing.
- Decision rule
- Set the meaningful effect, required sample and analysis plan from baseline traffic after claims review. Keep control if inconclusive or if conversion improves by overstating health or reliability expectations.
- What could muddy the result
- Sleep-related seasonality, daylight-saving changes, feature launches, entitlement changes and the balance of alarm-versus-tracking intent can affect results.
