Until now, it has been mandatory to create a user account to start using Lookmark. That has not been a great user experience. In fact, on almost 40% of the devices that downloaded the app a user account was never created. Accordingly, many potential users never got a chance to see if Lookmark would be useful to them or not.
With this release, you can get started using Lookmark without creating a user account. Later on, when you know more about how the app works, a free account can be created to take advantage of more features.
A user account is still needed to sync content between devices, to save content from one of the desktop browser extensions, and to enable data recovery. But now it's up to the user.
The widget is simple, but hopefully useful. It lets you open the most recent lookmarks from Notification Center. On 3D Touch enabled devices, it's also available when force touching the app icon on the home screen. Enjoy!
