What mobile metrics do you measure?

What are the top 5 metrics to watch to measure the health of a mobile app?

• Specifically focusing on retention, what do others in the mobile app space look at to measure an apps health? Active users by cohort, session length, number of users with 10+ sessions per week, etc.?

• Answer:

  Conversion from view to download. Retention. Measure not only 1-day retention, but also 7-day retention and 28-day retention which show the long-term retention. Engagement. Use metrics like number of sessions by user and average session length. Users Online is also good metric especially for online games. Size. DAU, WAU and MAU. And it is better to use LDAU (loyal DAU) instead of DAU, because is doesn't take into account the one-day users. Monetization. Use ARPU, ARPPU and the total revenue (without commissions). And don't forget that the metrics will inform you better when you apply them not by the whole set of users but for each user segment:) Here's a review of mobile metrics made by http://devtodev.com service: https://www.devtodev.com/promo/blog?id=10058#blogs
