Pollenkoll is a free lifestyle application available on iPhone that offers daily pollen forecasts for those who suffer from pollen allergies. The app provides information from 16 different measuring stations located in different parts of Sweden. For users who do not live near any of these stations, the app offers a crowd-sourcing feature where users can share information about their allergy symptoms to get a better understanding of the pollen situation in their area.

Users can set which types of pollen they want to receive forecasts for and can also activate pollen alerts to receive push notifications when there are changes in pollen levels in their chosen location. In addition to daily forecasts, Pollenkoll also provides information about pollen seasons, nearby allergy specialists, and various treatment options.

The app covers a variety of different pollen types, including alder, elm, ragweed, birch, beech, oak, grass, mugwort, hazel, and willow. Pollenkoll is a helpful tool for those who suffer from pollen allergies, providing them with the necessary information to plan their day and alleviate their symptoms.
