I think of a satisfied user as one who believes the app does what it is intended to do and does it better than any other app. Retention rate is not a good measure for this, IMHO. User retention rate is a measure of how useful the app is to the general public. Rating is a measure of the quality of the app. A user may be satisfied with an app but if its not as useful as their other apps then it will be uninstalled as soon as space runs out. I get the impression that the vast majority of downloads are from "curious" users. For a niche app which is high up the rankings, many users only want to download it to see why it's so higly ranked, They have no intention of using the app, so it will be uninstalled pretty quickly. For my main app, users 10 times more likely to rate pro version than free version, and 20 times more likely to leave a comment. Free app rated 4.5 (50% active installs), paid app rated 4.9 (70% active installs, 10% refunds). -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
