One of the greatest challenge on any mobile client is the amount of data to present vrs available space to do that. It can be completely solved by using pinned steps which requires a bit of space from the top of the screen only.

What is tricky, however, is how to store the data that changes/is added dynamically along with User Steps that user goes through. So that every time a pinned step is triggered, it's updated with a new data from the most recent User Step. It is possible to do that but requires a rather complex work-around which can be complex to maintain.

Have a look at the example of the workflow, an idea for an improvement and a movie that shows the final, end-client effect.
