Not free
Response from developer
Dear customer, we are sorry you had a bad experience using our app. Unfortunately, the fax sending service is not free for us. We pay for every page that our users sent so we can't provide this service for free. As for card information, it's not our requirement. This information is required from you according to the rules of payment through the App Store account. You can get a free trial and cancel it in App Store settings, so you would not be charged when the free trial will end.

Dear customer, we are sorry for this situation. If your fax could not be delivered, there is probably a problem with the recipient. To see the failure reason, press the three dots menu and select Details. There you will see an error description. You can also send us your recipient number on our support email support@fax-app.com, we will check it and give you the information about the failure reasons. Hope it will help, Fax App Team
