How to send fax via phone? What apps I can use for that?

[tTow]

I found out how to fax something from iphone and downloaded this new app. With its help I can easily  e-sign any paper on my phone screen, scan it and send. What could be better. it's a must have app for business. Also I can track the status of every sent document and make sure the recipient gets my faxes.
