I have downloaded a free app called "myGardenAnswers". I take a photo of a flower and it tells me what it is - sometimes. Since the app is from Nth America it is not always accurate, especially with Australian natives. You can also pay to Ask an Expert. I have never done that because I usually find out what plants are eventually by asking neighbours etc. However, I am sure that facility of the app is useful. I suggest if you haven"t found an alternative, download it and give it a try.
