Description

From the listing uploaded by “appupdater”.

Bitten by a tick? What to do. Follow these tips for removing ticks. The risk hazard map shows the current tick bite risk in Switzerland and Liechtenstein. Log tick bites and sightings in the tick diary. The reminder feature lets you compare pictures of symptoms with the bite on your body. If you see signs of infection when examining the bite, consult a doctor to determine whether you may have contracted Lyme disease.  Bites and sightings reported anonymously are shown as pink or turquoise dots on the potential risk map.
