Hello Mike, See my answers below. First, are you planning on developing a version for Android? Of course, we already have nearby explorer which is a great app, but choice is a good thing. Charles: Nearby Explorer is a great option, as for us nothing is in the works right away, we would need to get a sponsor to help fund the development effort needed because the market is so small in comparison to the Apple market. Also, does the seeing eye app include its own TTS engine, or does it rely on voiceover to speak everything. Charles: We do not have our own TTS, but we do use pre-recorded wav files like we do in our other Sendero products, with all the same sound effects indicating an approaching turn, turn now, continue straight, intersection, and arrived near destination. If it uses voiceover, does this mean that if you lock your screen, updates will not be spoken as you move around? Charles: Correct, currently the app doesn't work in the background. This is high on our list of features that we will have users vote on.
