Compare Handwriting

I bought this app to compare handwriting samples. After a small wrinkle trying to download the full/paid version (since this is not automatic) but which the developer resolved, I was good to go. It works nicely, the interface is clean & simple and it’s easy to use. There are a few tweaks I could suggest to improve it (hence 4 stars) but I would still recommend it to people.
