– Get data on iOS and Android user interns of:

    – number of users in each age
    – Geo locationns
    – Income
    – Mostly accessed apps
    – Time spent on phone
    – Number of users on iOS and Android

The age, mostly accessed apps, geolocations, number of users and time spent on phone could tell us a few things:

    – Is there a significant age discrepancies?
    – Are users on iOS and Android focus on different apps?
    – Does iOS users travel more frequently than Android users on average in terms of distances and time?
    – Even the percentage tells iOS has higher %, what about number of users?
    – Time spent on phone: if the 65% Android users and 30% iOS users spend much less time on the phone, that just means these groups of people may not be aware of different apps that are available on their phones

– How the users get the app

    – In what ways do most users on iOS and Android get the app? Through recommendations? Direct download from App store? Or the phone they get come with the apps?
    – If the iOS phones come with the app, or put instagram on top of the list in recommendations, but the Android does not, then that could be the problem.
    – Test recommending apps on both iOS and Android and see response rate.

– Investigate the user feedbacks

    – Is it possible that the user experience for using Instagram on iOS and Android is so different?
    – Or does it simply because running on Instagram on Android devices is a pain in the ass?
