For the ACA to work young people need to enroll. Could there be an App for that? I don't know, but TPM and Josh Marshall have a story about about two programmers in San Francisco who have created "Heath Sherpa" - http://www.thehealthsherpa.com/
I think I read somewhere that this was part of the ACA development in some way or fashion but that it hasn't been prominately used.
I'm no programmer or techie, so I can't speak to what this website might mean, but perhaps those types can.
According to the TMP (http://talkingpointsmemo.com/...)
it's definitely not a replacement for HealthCare.gov. But a few guys out in San Francisco have put together something called thehealthsherpa.com, which really quickly tells you what policies are available in your area, what subsidies you are entitled to based on your income and who to call or what site to go to buy the actual coverage. From what I can tell it seems to be the work not of a commercial entity or even an organization, but just some very public-spirited programmers.TMP also says other sites like HealthSherpa are expected to be popping up soon. Perhaps Apps too?
Now, to be clear, this does not replace healthcare.gov. You can't buy through the site. You can't prove your income levels through the site. But to the extent people are tripped up are finding out what's available, what the subsidies are etc. it's extremely fast.
Come on young people, help make this thing work - use that social media/networking prowess we hear so much about. Especially if you voted for Obama!
