We do have legal disclaimers related to this field (though they are currently not shown in the beta app). SCiO is not a medical device and should not be used as one.
By the way, we should mention that % confidence value is in our road map and will be available for developers in the near future via SCiO lab and the mobile SDK.
As for publishing applications, you are right. Adding “apps inside our app” is definitely in our road map.
Developers will be able to publish their applications either on their own mobile app (using the mobile SDK code packages) or by using Consumer Physics platform.
