How to see how many times your app has been downloaded?

If you have a white-label app you might want to know how many times your app has been downloaded.

iOS

For Apple devices, you can get this information from the statistics in your Apple developer account. Visit https://developer.apple.com/

Android

Find your app in the Google Play Store and you will see the number of downloads under its name. However, Google only provides an estimate (i.e. 500+ downloads).
