Tick

Tick is a practical guide and tracking app for managing tick exposure and bite safety in Switzerland and Liechtenstein. Get immediate, evidence-based advice on removing ticks correctly, then document your encounters in the integrated tick diary.

The real-time hazard map displays current tick bite risk across the region, updated with anonymous reports from other users. This crowdsourced data helps you understand seasonal and geographic patterns in tick activity, so you can plan outdoor activities with better awareness of potential exposure.

Track tick bites and sightings as they happen. The reminder feature lets you monitor symptoms over time and compare pictures of any skin changes with your original bite location. This ongoing record is invaluable if you need to consult a doctor about possible infection or suspected Lyme disease — having detailed dates and visual documentation can speed diagnosis.

The information section covers tick-borne diseases, TBE vaccination guidance, and the lifecycle of Ixodes ricinus, so you understand the health risks and prevention measures. Your anonymously reported sightings appear on the map as data points, contributing to applied research conducted by Zurich University of Applied Sciences and supporting public health surveillance efforts across the region.

Developed by ZHAW in partnership with the Federal Office of Public Health and the National Reference Centre for tick-transmitted diseases, Tick combines citizen science with practical safety tools. Download Tick to stay informed about tick activity, document your own encounters, and help protect your community.
