Can't save unless you make in-app purchase – Silhouette - Image Maker App Review

There are several major flaws in this app that keep me from giving it a higher rating. But I can use it to give me some raw edits that I can (hopefully) tweak elsewhere. First, you get ads in this initial version, which won't go away until you make the in-app purchase; nor can you save any edited images until you buy the app. It only cost me $1.99, but there is no clue about that until you actually try to save something. Next, when you repeatedly hit save, while editing a single image, every saved image is the same! It only saves the most recent changes to ALL of the images, instead of having several iterations of edits saved. The only way around this is to bring in a new copy of the photo to edit, save those edits and repeat. Turning off "background" is misleading. Instead of blocking the background of the image itself, it brings in whatever pattern is showing outside the image, so that it is now superimposed across the entire image. Not useful! Selecting the far right "Image" button in Background or Save mode is supposed to allow you to be able to add a preferred pattern to the image. But it doesn't just go in the background, it goes over the entire image. And once selected, it can NOT be reversed! There is no way to even make it "none"! The best you can do is to bring a new copy of the original image in, to be edited all over again. Lastly, the user manual is simplistic at its best. Super short statements, suffering from poor language translation. No real depth of explanation. A tutorial for newbies wouldn't hurt, either.
