This screenshot shows the app analytics data sent by two different #iOS apps: Duolingo and Tinder. What's the likelihood that both apps are installed on the same device? 💯? 🤯

Both apps use Unity Ads. The data in the screenshot is collected by the Unity Ads framework included in these two apps, and any app that uses Unity Ads. The data is sent to the same Unity server. As a result, Unity Ads can easily fingerprint users and track them across different apps.
