I'm intending using Localytics (http://www.localytics.com) for an app which will be released on both iPhone and Android. My question is: Should I aim to use a separate app ID for the two platforms? I'd really like to just use one (so that all my analytics apply to both apps) but I notice that some things like "operating system version" just appear as a bit of a mess if I use the same ID for both.
There's nothing in their integration guide mentioning this - anyone have experience of this one way or the other?
I work on the Localytics SDK team and I'm happy to help.
While there is no technical reason you can't share a single key, we recommend keeping them separate. In addition to having a combined list of devices, operating systems, app versions, etc, your users likely behave differently on each platform. Using a single key will make it more difficult to see platform specific trends in your app usage.
