I absolutely love this app, and I know it will help me as a totally blind person. I am also glad to see that the developer has indeed implemented the back camera as well as giving us a choice of also using the front camera. I’m very pleased with this purchase. I will recommend it to others. The one thing I would like to see, added, is the ability for the app to tell us what objects we are actually approaching, especially when text and or speech mode, or both are enabled. It would be nice to know for example, if I am approaching a table, coat rack, wall, door, etc. other than that all of my previous comments still stand, I really like this app, and I find it very sensitive as far as detecting obstacles. Now, if it can just tell us what the obstacles are, that it is seeing, it would be absolutely perfect.
