Hello Kyle,
Unfortunately, lifetime analytics does not provide any performance reports for mobile applications but what you can do is access and generate logs from Service Center and analyze from there.
There's an analytics tab in Service Center that should be good enough if you generate reports such as "Daily Activity", "Screen Performance" or "Queries Performances". These reports should be good to cover what you wish to analyze. It may not return back any application index scores but it can provide you the insight you need to be able to assess your applications further.
I have attached a screenshot for you and if you're unable to see that tab, try reaching out to the environment or platform admin.
