What is the most used app in Sweden?

Could you please elaborate on the topic of "What is the most used app in Sweden?" I'm particularly interested in understanding the criteria used to determine the popularity of an app in Sweden. Is it based on the number of downloads, active users, or some other metric? Also, I'm curious about the types of apps that tend to be the most popular in Sweden. Are they social media apps, utility apps, or perhaps something else? Furthermore, I would like to know if there are any unique or locally popular apps in Sweden that might not be as well-known globally. Finally, how does the most used app in Sweden compare to the most used apps in other countries? Is there any notable difference or similarity? Thank you for your insights.
