Absolutly love this app.... The color filters are so effective.... I use them for finding depth variations in rocks and by doing so brings ancient drawings that are carved into stone that are not easily noticed by the naked eye.... My only recommendation would be to add more color variation filters.... But what you have is very effective.... Good job people... Taker easy..

The greatest of all. I've been waiting for a long time to get an app like this to see what the labels say. Now I can read the fine print on everything. It zooms in crystal clear letters and I can see them a mile away. Thank you so much for sharing your app with me and I hope the other people who needs help seeing fine print download it also.
