Is it possible to track downloads on Android and iOS applications at the same time?

Question

I am trying to track the downloads of an Android and iOS application at the same time.

The problem is: I develop the applications to some clients but I have to upload the applications in their respective Android/iOS developer accounts. I need to track the visits of each application because they will pay depending of the downloads of the application. All the applications are uploaded to Google Play and iTunes Connect.

What I need: Some way to track downloads on both OS(Android and iOS) that allow me to track the downloads of the desired applications that are not on my developer accounts.

Is there a way to track the downloads of some applications that are in both Android and iOS?

EDIT: I am trying to track the downloads of an app that is on a third person developer account because I need to track their downloads although they change their password accounts (I have them right now). I prefer not to add additional code to that applications if possible.

Thanks in advance!

Answer 1

You can track them using any analytics framework, and some health frameworks. Firebase (former google analytics) will do. Fabric will do. Splunk Mint will do. Since all of them are independent of the store account, the only thing you'll need, in general, are the package name, and in some cases, the developer key.

Google Android Developer cosole automatically does that for you
