The following graphs show the percentage change in app store search interest over time, for the top 50 apps and 50 search terms in each category. This analysis combines proprietary data with search popularity data from Apple.
As the outbreak is in a different stage in each country, we used various periods for the pre / post comparison. PRE period = dark blue, POST period = purple, and earlier weeks = light blue
The dotted baseline is calculated as the average of the dark blue (pre period) bars. The percentage change is calculated as post period / pre period.
The following periods have been used in the different countries:
US, UK, DE, ES, FR: last 3 weeks / 3 weeks before that
IT: last 4 weeks / 4 weeks before that
JP: last 5 weeks / 1 week break (Bank Holiday) / 5 weeks before that
