FaxFlow: Send Fax from Phone screenshots
FaxFlow is an Android app from Mobile Flow Ltd that turns a phone into a fax line. You scan a document, enter a fax number and the app sends it, and it can also give you a US number so faxes come to you instead. The pitch is simple: no fax machine, no landline, and a job that takes about a minute.
That is a narrow job, and the developer is upfront about it. Plenty of offices still ask for a fax, and the people most likely to need one are dealing with tax forms, medical records, insurance claims, signed contracts or bank paperwork. If you are in that position and the nearest print shop is a detour, having the whole thing on your phone is the main reason to consider this app.
More than 100,000 installs and a 4.8 average across nearly 30,000 ratings suggest a lot of people have found it useful for exactly that errand. It is free to download and carries no ads, though sending and receiving sit behind a subscription.
Scanning a page and getting it delivered
The feature the developer leads with is the one I would judge the app on: sending a fax. You point the camera at a paper document and the app scans it, with automatic edge detection and cleanup, so a form photographed on a desk should come out looking like a page rather than a snapshot. That matters because the receiving office is usually a bureaucracy that will reject anything it cannot read.
You can also skip the camera entirely. PDF, JPG and PNG files can be attached from the phone or from Google Drive, which is the route I would expect most people to take for anything they already have digitally, such as a signed contract or a downloaded statement.
Your name, number and a brief note can go on a cover page. It is a small thing, but faxes to government offices and medical practices often get filed by hand, and a cover page is how the person on the other end knows what they are holding.
Each fax comes with a delivery receipt that can be shared. That receipt is the part I would value most, because it is the evidence that the document arrived when someone later claims it did not. If a fax fails, the app retries on its own rather than leaving you to notice and start again.
Receiving faxes on a US number
The other half of the service is inbound. A US fax number is included, and anything sent to it triggers an instant notification. For anyone who deals with an office that insists on sending paperwork back by fax, this removes the need to be near a machine at the right moment.
Sending covers fax numbers in the US and Canada as well as internationally, so the app is not limited to one country's traffic. The developer describes faxes as encrypted in transit and carried over dedicated phone lines, and notes that this is part of why medical, legal and government offices continue to use fax at all. I would treat that as the developer's framing of the service rather than a guarantee about any particular recipient's handling of your document.
The combination of sending and receiving is what separates this from simply photographing a form and emailing it. Some offices will not accept email, and a fax number that works in both directions means you can hold up your end of that exchange from a phone.
What the subscription covers
Downloading costs nothing, and scanning, cover pages and fax preparation are free. A paid subscription covers sending and receiving, since each fax runs over real phone lines the company pays for. Weekly, monthly and annual plans are on offer, and the developer says you can cancel at any time.
Send a single fax on the weekly plan, then cancel it. That is a reasonable fit for an occasional errand, though it is worth reading the terms of whichever plan you pick before you commit.
The app offers in-app purchases and shows no advertising. The developer's contact route is inside the app under Settings, or through the company's website.
Getting a fax out the door without trouble
Because the app is built around one task, most of the practical advice is about the document rather than the software. Scan in decent light and check the preview before you send: edge detection and cleanup help, but a page photographed at an angle in a dim room is still going to be a poor fax, and a rejected form means starting over.
If you already have the document as a file, attach it instead of rescanning. A PDF that came straight from a bank or an insurer will be cleaner than anything a phone camera produces, and it saves you the step of printing something just to photograph it.
It helps to know the recipient's fax number before you begin, since the whole process is built around entering it and sending. Adding a cover page with your name and number is worth the extra moment for anything going to a records office, where the document may sit in a queue before anyone looks at it.
Finally, keep the delivery receipt. It is the simplest way to answer a later question about whether something arrived, and it costs nothing to hold on to.
A focused tool for the offices that still ask for fax
FaxFlow does one job and does not pretend otherwise. It suits people who occasionally have to send paperwork to an office that only accepts fax: a tax filing, a prescription, an insurance claim, a signed agreement, a bank form. For those errands, having scanning, sending, receiving and a delivery receipt in one place on a phone is genuinely more convenient than finding a machine.
The subscription is the main thing to weigh. Sending and receiving are not free, and the cost only makes sense if you expect to fax more than once in a while, or if you want a US number that faxes can arrive on. The developer's weekly option is there for the one-off case.
If your paperwork regularly lands at a fax-only office, this is a straightforward thing to keep on your phone. If faxing is a once-a-year event, the weekly plan is the sensible way in.
The short verdict
FaxFlow is a focused, ad-free way to send and receive faxes from an Android phone, best for people who deal with fax-only offices regularly.

FaxFlow: Send Fax from Phone: frequently asked questions
Can I send a fax from my phone without a fax machine or landline?
Yes. FaxFlow is built for exactly that: you scan a document with your phone's camera or attach a file, enter the recipient's fax number, and the app sends it over phone lines it operates. There is no fax machine or landline involved on your side. The whole process takes about a minute.
What does FaxFlow cost to use?
Downloading costs nothing, and scanning, cover pages and fax preparation are free. Sending and receiving require a subscription, sold as weekly, monthly or annual plans that can be canceled at any time. If you only need one fax, the developer suggests taking a weekly plan, sending it and canceling.
Can I receive faxes with FaxFlow, or only send them?
Both. The app provides you with a US fax number, and faxes sent to that number arrive with instant notifications. Sending works to fax numbers in the US and Canada as well as internationally. That two-way setup is what lets you handle an exchange with an office that insists on faxing documents back.
What kinds of documents can I fax with it?
Paper documents can be scanned with the camera, which detects edges and cleans up the image, or you can bring in PDF, JPG and PNG files stored on the phone or in Google Drive. Your name, number and a brief note can go on a cover page. Typical uses include tax forms, medical records, insurance claims, signed contracts and bank documents.
What happens if a fax fails to go through?
The app retries failed faxes automatically, so you do not have to notice the failure and start the process again yourself. Every fax also comes with a delivery confirmation and a receipt you can share, which is useful when you need proof that a document arrived. Messages go out encrypted, using phone lines reserved for fax.
