I looked into Lumos and Testflight, but found out that the live versions won’t show the data by individuals, which makes it difficult to tell what an individual user’s experience was like. Are there cost-effective mobile analytics tools that will show individual player data?
Take a look at GameAlytics. It features tight integration into Unity, and provides a tracking for common types of analytics events out-of-the-box, without any additional configuration. They also feature a free tier, which is useful during development.
