I like that we can see exactly who has downloaded our apps from google play or apple store (we have over 100k downloads across both platforms).
The reporting of this data makes it easy to identify areas where we need more engagement with current customers. It also helps us understand what new features would be useful in order to improve user experience by maximizing their usage time. There isn't anything i dislike about aditkeev other than some times you may not get all your analytics back within 24 hours which could delay an issue being resolved as quickly as possible but overall its been great!
