Panorama Stitcher Mini 4+

I can't say I was expecting much. I started a big scanning project of old family pics and I came across some big prints dating back 70-80 years and more. They were quite a big larger than my Epson V600 printer's bed, and my attempt to stitch them together didn't go so well. So I tried the free version and the results were amazing--going to the paid version was a no-brainer.
More recently I needed to digitize some large printed documents, including a survey of my property. When I did it in two halves, the app couldn't find enough matching details. Easy fix: do a additional scan along the middle, and the three images had more than enough overlap for the app to match detail and so stiched them perfectly.

I have a flatbed scanner that scans up to legal 8.5x14 size but I also frequently need to scan larger photos or drawings. I have found this is a great app- I scan each corner of the artwork and then run them through this image processor and I can get great high quality stitches of the photos!

The developer was also super responsive- I had misunderstood how to use a particular feature and emailed the support address and they responded almost immediately- it was incredibly nice. I decided to upgrade to the paid version of the app because this was so useful.

Went to Grand Teton and took some photos. I didn’t have a good wide angle lens and it was just a couple minutes stop on our way back. All I had was a 35mm ZM lens which I knew has some distortion. But regardless wanted to give a try to take three photos horizontally of the Teton.
Back home, edited the photos, I carefully made sure exposure remains constant. Loaded this app to stitch. It actually automatically adjusts exposure and is smart enough to stitch three photos together. It also allows you to adjust the distortion direction.
The result is a 47M large jpg file that I’m quite proud of. This app worth five stars. Give it a try you won’t be disappointed.
