Beaten to it (again)
So it turns out that I was on to a good idea with my iPhone app. The problem is that on the 6th Feb someone else released exactly what I had in mind. They even used the same open source libraries as I was going to use. That’s the second time in recent months when someone else has beaten me to it. Unfortunately there isn’t much opportunity to differentiate my app from what exists, with a similar approach and functionality the only room for improvement is simply charging less. The underlying problem with accuracy is the quality of the iPhone camera and it’s lens, but that’s something only Apple can really fix. The amateur (me) going after the software company with a “me-too” product isn’t going to work, so it’s back to the drawing board.
