I'm Giacomo and I'm part of the team that is developing Specular, an app that aims to help visually impaired people. The user can take a picture of something he or she needs help with and record an audio question. This is sent to a community of sighted people that will look at the picture and reply.
We just started our beta testing as a forum discussion and we will release on it the beta version of the app in about 2 weeks. We would like to increase our number of beta testers and that's why I'm writing you here. The registration link is the following: http://www.bespecular.com/become-beta-tester
If you have any question, don't hesitate!!
Have a nice day,
