Hi! I recently had the same question and spent some time reading reviews before deciding. Municorn Fax App turned out to be the option I chose after reading a detailed comparison, and it’s been simple to use for scanning and sending documents from my phone. If you’re still comparing services, I recommend visiting https://presentingperl.org/best-app-for-faxing-in-2026-top-8-fax-apps-reviewed and reading the full review there—it explains the differences between the leading fax apps and helped me make my choice.
