Critical field data, readable at a glance.
Kestrel LiNK connects to Kestrel weather meters and data loggers — professional-grade instruments made by Nielsen-Kellerman and used by meteorologists, military, firefighting and field teams — via Bluetooth. The app shows live environmental readings, logs and graphs historical data, and alerts users when critical measurements cross the thresholds they've set.
For its users, the data isn't casual: readings like wind, temperature and heat index inform real operational decisions in the field.
Real-time environmental data from the connected meter
Notifications when critical values cross set limits
Graphs and calendar views for point-by-point analysis
Pairing, sync states and multi-device handling
Who Uses It
Meteorologists, agriculture and industrial teams monitoring on-site conditions
Firefighting, military and event safety tracking heat stress and wind
Anyone logging environmental history for analysis and reporting
My Role
I continued the development of an existing product — a design system and core screens were already in place. My work was driven by evolving user needs: designing the next features the product required.
- Designed new features within the established design system, keeping full consistency with existing screens
- Extended data-monitoring interfaces: live dashboards, historical logs and measurement views
- Designed around device connectivity — Bluetooth pairing, sync states and multi-device management
- Prioritized clarity of critical values and deviations over visual decoration
- Worked in a Scrum team with PM, business analysts, developers and QA
Challenges & Solutions
Users rely on the app to spot deviations in complex environmental parameters and react in time.
→Designed for instant readability: clear hierarchy of values, visible thresholds, and alert states that can't be missed.
A field utility tool is judged by how reliably it works, not how it looks.
→Took an engineering-minded approach: legibility in outdoor conditions, predictable patterns, zero ambiguity.
The design system and part of the screens already existed.
→Extended the existing language feature by feature, so the product evolved without visual fragmentation.
