Answers to your questions:
1 - Living wills - This is one of our most requested features. We expect to have a national footprint within the next few months. We will notify all of our customers in each state to let them know as it becomes available.
2 - Interface and notifications - We are working on a significant improvement to the UX. We're thinking really hard about how, when and where to share the right amount of information. As adam mentioned, this is a particularly sensitive topic which we really want to get right.
3 - Business model and fees - We currently do not earn fees from our customers or providers. The service is truly and unconditionally free. We're taking a novel approach to this problem that hasn't been done before and will share more when the time is right.
Look forward to feedback from the hn community as we evolve.
