The research question
Are device wear time, data completeness and participant burden adequate for the proposed research question?
Proposed design
A technical and participant pilot using a specified device, version and data-export route, paired with a short diary.
Illustrative design: 2- to 4-week pilot; setup and recruitment are scoped separately.
Data to collect
- Wear time and sync gaps
- Timestamp and unit consistency
- Diary completion and device usability
- Agreement between related measures
Planned outputs
- Device and diary data-quality report
- Missingness and synchronization analysis
- Recommendations for a larger study
What we confirm with you
We agree the population, sample size, country, collection tools, analysis plan and budget. Collection starts after the required consent, ethics or other permissions and a signed scope are in place.
- Confirm device access, export rights and supported integrations
- Assess fitness for the intended outcome
- Do not label exploratory signals as validated clinical biomarkers
Clinical records, laboratory results, photographs and device integrations are included only when access, collection quality and permitted use have been verified. Self-reported findings are identified as such.

These published sources explain the research need or method. They are not RIDLY customers, endorsements or purchase commitments.
- FDA guidance on remote digital data collection
Digital study tools need fit-for-purpose selection, verification and participant usability assessment.
