Capture Mobile App Screenshots

I'm collecting market research on mobile apps and want to compare User Interfaces + User Experiences. Your job is to go through the driver-version of the Uber app for iPhone and take screenshots of the entire flow of relevant processes, as well as use cases. Note, this is not the client experience that we'd like documented. We're looking to document the experience of a driver Processes that need to be documented (via screenshots) include the following: +Pre sign-up/sign-in +New Driver Sign-up/Registration Flow +Profile settings/customization + What the app looks like once you're logged in (all screens) + Is there a dashboard of jobs completed that you see after you've logged in? + Screenshots of receiving a job request +Screenshots of accepting jobs from customers (and any additional screens that might be available that you'd use to evaluate the customer) + Screenshots of what the app displays when you're driving to a destination and when you get there. +Screenshot of what the app displays immediately after arriving at a destination. +Sign-in Flow (returning driver)
