Wunderlist is a to-do app, and the above screenshots are from its first time user experience on an iPad.

The good bits:
Wunderlist presents a product tour up front. But instead of forcing someone to read all the way through, the app persistently displays options for skipping it.  While Sign Up and Log In are the most visually prominent options, there is also an option to Try Wunderlist so that users can explore its functionality before committing to an account.

Users who explore Wunderlist without an account are able to work with limited functionality. They can create lists, add/remove items, mail lists and customize with a set of predefined themes. People are prompted to sign in when they try to execute a feature such as inviting colleagues to collaborate.

To be improved:
After tapping “Try Wunderlist” in the initial product tour, a second product-tour-like overlay pops up showing “What’s New”.  To a new user’s eyes, these features would be just as new to them as the rest, so the app could consider incorporating these panels into the initial product tour. This will avoid putting an additional barrier between potential customers and the actual product.

There was no inline help for features once past the product tours. While this can be OK for pure exploration and simpler feature sets, there were some confusing moments that could have used a hint. For example, it was unclear why items listed in someone’s “Inbox” list had the invite button disabled, whereas in other lists it was enabled.
