I’ve been using the desktop version of this app for a couple of years and have found it very useful. Unfortunately, I assumed that this would work in similar fashion. Boy, was I wrong! On the desktop version, each brand is given a match accuracy that allows you to choose the pencil that is closest to Milt the photo. In some cases, one brand can very close (say, 89%), while the others may be much lower (65% or less). Without that information, I don’t feel this app is of use to anyone. I wish I had been more careful before purchasing this watered down version. I have uninstalled it, since it’s of no conceivable benefit to me. I would not recommend this to anyone.
