WeTransfer's mobile adaptation

What does WeTransfer do? It puts an end to the irritating messages of “The file you are trying to send exceeds the attachment limit,” “Your mailbox is full,” and “Downloading. 333 minutes and 1 second remaining.” In other words, it makes sharing big files, slick.

Because digital assets, like videos and high-res, require greater computing power, WeTransfer is routinely used on desktop devices. This is where WeTransfer is known best. 

But as smartphones get ever more powerful, more file sharing is going mobile where the user's problems, needs, and wants are all different. This is why delivering a great mobile experience takes more than a few tweaks to a desktop design. It needs a full adaptation, in value, functionality, and style. And this is precisely what WeTransfer has done here.

Why this is really good UX:

• The UI adheres to Apple's human interface guidelines for an app that integrates seamlessly with the Apple platform. As users are familiar with the style, layout, and functionality from their experience with Apple, they will intuitively be able to use the WeTransfer app.
• To increase the chances of user adoption, WeTransfer knows they have to present the “aha” or “wow” moment as early on as possible. This is done in Steps 2 and 3, where the value is visualized with the app in action on a mobile device.
• Described in the Hook Model as the investment phase, WeTransfer asks users to do a bit of work by setting up their first board, because the investment of effort makes re-engaging the user with the app more likely. Users value their labor, which means they are less likely to leave their work behind.
• Action-driven tooltips are used to reduce friction and avoid redundancy. WeTransfer uses these to prompt users in the right direction—to the end of the flow—without the user having to interact directly with a tooltip.
