4xScanner - Smart Stitch! App Reviews

Crashes 100% of time after pushing "use" button.

Crash after use button

I only tried this a couple of times, but the results were miserable. If just one of the images wasnt accepted, you had to take it again, and it would have to start the lengthy stitch process over again when you do. The resulting stitched images was stitched very poorly, with huge jogs between the pictures. The interface made sense and was fairly slick, but this app was a waste of money for me. It doesnt solve my problem of scanning large documents.

This was a worthless purchase. I am so sorry I paid for it. It didnt work at all on my iPhone 4. It crashed every time I tried to load an image from my camera phone. I tried contacting the developers, but there was never any response. If I could rate it lower than one star, I definitely would do so.

I read prior reviews that reported nothing but problems, but decided to give it a try. It did not work on my iPad 2 with iOS 6.1, but does work on my iPhone 4S with iOS 5.1.1. I have been able to do several two, three and four-part scans that it successfully integrated into single detailed images. One needs good even lighting on the image source, hold the camera parallel to it and to take all shots from the same relative angle. Positioning each shot intelligently with sufficient overlap I found good results were obtained. One test was to scan an 18-inch long store receipt that had been folded and crinkled in a pocket. Roughly flattened but with many undulations still present, I scanned it in four photos (three would have worked) and ended up with a sharp single image. In this case, the seams were visible, but didnt affect the readability. In other instances I found the seams invisible, much depended on the lighting and angle of the group of shots. If you need to stitch together high quality landscape photos, use an App designed for that purpose, but this works for my infrequent utility needs. Long receipts, occasional map images, parts diagrams, any instances where capturing a good functional view of a large image is more important than a pristine and seamless copy. I will be using this App frequently.

I was unable to stitch any two images. The app would capture images and upon pressing stitch, it would pause a bit and crash. The same result both in iPhone 3GS and iPad 2.

Not even a little bit Im going to try to get my money back
