Field Notes
An offline-first inspection app that helps field teams record evidence and finish reports before leaving a site.
Context
Inspectors were taking photographs on site and rebuilding the report later from memory, often with weak connectivity and incomplete notes.
Contribution
I designed the mobile workflow, built the offline data layer, and worked with inspectors through three field trials.
Constraints
- The app had to work for an entire shift without a network connection.
- Evidence could not be lost when devices ran low on storage.
Key decisions
- Saved each answer locally as it was entered instead of waiting for form submission.
- Made sync state visible beside each report and attachment.
Outcomes
- Reduced return visits caused by missing evidence.
- Cut the median report completion time by 18 minutes.
