Basic interface problem; plus, free version does NOT convert images! – Knitting Chart Review

I've been trying to find an app that converts an image into a knitting chart. Alas, discovered two major problems with this app. 1. At first, it looks as if the app cannot do this. When one starts a project, the choices are Draw Chart, Row Counter, PDF File, and Ravelry File. No choice for an Image Conversion appears! That's confusing. We're not trying to draw a chart, but convert an image into a chart. That choice should be one of the original ones! So, given that no directions and no manual are provided, I tried to save an image as a PDF. But the app doesn't read PDFs stored in iBooks! It also won't read a jpg file. It also lists all sorts of files that cannot be converted. Pick one and it just sits there! OK, so eventually, after much frustration, I tried Draw Chart. One is presented with a host of indecipherable icons — there should be pop-up text tips for each or a text caption below each to explain what they do. (Users could have an option to turn that off once they know the program.). Nothing seemed to work! Eventually, I tapped on the ellipsis, an odd choice of an icon, where I found Import Image as a Color Chart. All of this is far too convoluted. As noted, Convert Image to Chart should be a choice on the first Project screen. 2. Then, I encountered the second big problem. First, though, there was no guidance as to how many Columns and Rows to use. I kept trying different amounts, but the resulting color grid looked nothing like the original image. Finally, in desperation, I tried 80x80. That took forever to convert, but the resulting grid looked like the original image. However, when I then tried to convert that to a chart, I received a pop-up message telling me that conversion to a chart was *only* available in the Pro version and that I would have to pay and upgrade! That's an incredibly frustrating result. The app should tell the user that way before then; in fact, the Pro upgrade alert should pop up right when Import Image is chosen. As currently set up, this is truly off-putting; an unfriendly user design. I wasted a lot of time — first because the interface is convoluted (Convert Image should be a choice at the outset); next, because the Convert Image choice is hidden; third, because it's unclear how fine a grid is needed. and last, because the upgrade alert doesn't appear until AFTER the user has tried lots of things and spent lots of time trying to figure out the app works! —-> I still do not know how well this app converts images to a chart. <—— Finally, the blurb here in the App Store should explicitly describe which features are in the free app and which require an upgrade. That would save prospective buyers a lot of time. Now, all that's left for me is disappointment. I would urge the developer to make the design changes mentioned, and to include the conversion ability in the free app to let users see how well that works!
