What specific type of user behavior would categorize someone as a high-value candidate for app re-engagement targeting?

A user who has previously installed an app but hasn't opened it in a significant period, yet still exhibits behaviors indicating interest in related topics or competitor apps on X, would be considered a high-value candidate for app re-engagement targeting. App re-engagement targeting aims to encourage users who have downloaded your app but become inactive to return and use it again. Specific behaviors indicating continued interest might include: following accounts related to the app's functionality (e.g., following fitness influencers if the app is a fitness tracker), engaging with content about competitor apps, or using relevant hashtags. For instance, if a user installed a language learning app but hasn't opened it in 30 days, yet continues to engage with Tweets about learning new languages or follows accounts that teach foreign languages, they represent a prime opportunity for re-engagement with targeted ads highlighting new features or special offers within the app. The combination of past installation and continued demonstrated interest makes them a high-value candidate.
