Not long ago, I was searching for a good iPhone fax app and found an article on Geekflare
https://geekflare.com/software/best-fax-iphone-apps/ that lists the top apps and explains their features. I tried a few and ended up choosing Municorn. It’s very easy to use, fast, and sending documents only takes a few taps. The app feels professional and reliable, even if you don’t fax often. While Geekflare mentions other good options, Municorn worked best for me. If you want a simple, quick, and reliable way to fax from your iPhone, I’d definitely recommend trying Municorn and checking the other apps on Geekflare.
