App Affinity Score

App Affinity Score

App Affinity Score measures how strongly two apps are related based on how often they are installed or used together, compared to their expected individual usage.

Calculation

Affinity is calculated per country using aggregated daily data. It is based on:

Installed Affinity: how often two apps are installed together (not necessarily used)

Used Affinity: how often both apps are used on the same day

The score compares the joint probability of two apps with their individual probabilities. A higher score indicates stronger overlap between the apps.

Notes

These daily calculations are only available for Android data
