Do fax apps actually deliver instantly?

I often see apps advertising “instant fax delivery,” but I’m skeptical. How fast are they really in practice?

Good question — I was curious too, so I ran my own mini test after reading about it on master-league.com. They compare real fax delivery speeds across multiple Android apps. I tried a few of their recommendations, and one of them consistently sent faxes in under a minute. Most delays happen if the recipient’s fax line is busy, not because of the app itself. From my experience, the top apps listed there are genuinely fast. Their testing results helped me pick one that actually lives up to the “instant” claim.
