I am wanting some advice concerning whether I should purchase KNFB Reader or not; due to its high price, I want to make an informed decision before I go ahead and purchase the app. I currently have Prizmo and TextGrabber installed on my iPhone 5S; I have had one successful attempt at scanning a document using Prizmo but no success so far with TextGrabber. Does KNFB Reader have some advantages over these other apps that are worth the money? Furthermore, I am about to receive a scanning stand therefore will either Prizmo or TextGrabber be more effective when using the stand meaning that there is no need to purchase KNFB Reader? Finally, I recently discovered an app called Text Detective which seems to do a similar job to all the others. Is that also worth downloading or once I have a scanning stand, will the ones I already have installed be sufficient?
Thank you in advance for any advice,
