Welcome to Slippery Cities!

Slippery Cities is an Apple Watch app to alert pedestrians of slippery conditions in Helsinki, Jyväskylä, Kuopio, Lahti and Oulu.

During winter time, the risk of falling down is higher due to slippery conditions. With good shoes, anti-skid devices and timely road maintenance it is possible to lower the risk of falling. It is also beneficial to be aware of the danger of falling due to slippery conditions. Then you can prepare for the conditions using suitable shoes and - above all - being careful when walking outside.
