Let’s be honest: nobody wants to use a fax machine. But when a lawyer, insurance company, or government agency demands a "signed fax," you need a solution that just works—without making you hunt for a local print shop.
The Android fax landscape has shifted. We're seeing fewer clunky ports of old web services and more streamlined, mobile-first tools. After testing dozens, we’ve narrowed it down to the 6 best options for your Galaxy, Pixel, or any other Android device.
| App | Best For | Price Starts At | Free Option |
|---|---|---|---|
| mFax.to | Speed & Ease | Pay-as-you-go | No subscription required |
| Fax.Plus | Security / UI | $8.99/mo | 10 pages total |
| eFax | High Volume | $19.95/mo | No |
| iFax | Power Users | $12.49/mo | Limited trial |
| RingCentral (RingEX) | All-in-one Office | Contact Sales | Free Trial |
| MetroFax | Simple Billing | $15.00/mo | No |
The Quick Verdict
If you’re in a rush and just need to send one or two faxes without a recurring monthly bill, mFax.to is the clear winner. For those needing a permanent fax number for healthcare or legal business, Fax.Plus or eFax offer robust (though pricier) inbound features.
1. mFax.to — Our #1 Mobile-First Pick
Most apps try to trap you in a $20/month subscription. mFax.to is different. It’s built for the person who needs to send a fax right now. With their native Android app, the process is as fast as sending an email.
✅ Pros
- Native Android App: Fast, stable, and light on battery.
- Pay-As-You-Go: No monthly commitments. Pay only for what you send.
- Pro Scanner: Auto-crops and cleans up hand-signed papers instantly.
❌ Cons
- Focused on sending; high-volume receiving might need a dedicated plan.
- Minimalist design (not for those who love complex nested menus).

2. Fax.Plus — The Modern Standard
If you care about a "clean" look and need high-level security (like HIPAA compliance), Fax.Plus is a solid runner-up. Their Android app is polished and integrates well with Google Workspace.
- The Good: Swiss-based security, supports electronic signatures within the app.
- The Bad: The "Free" tier is essentially a demo (10 pages total, then you must pay).
- Pricing: Starts at $8.99/mo if you pay annually.
3. eFax — The Corporate Veteran
eFax has been around as long as the internet itself. It’s the "safe" choice for large corporations that need massive scalability and international reach.
- The Good: Massive infrastructure, plenty of local number options in 200+ countries.
- The Bad: The interface feels dated, and their pricing can be confusing with setup fees.
4. iFax — Best for Multi-Device Users
iFax excels if you switch between an Android tablet, a Windows PC, and a phone. It’s one of the few that offers a truly consistent experience across every screen.
- The Good: 24/7 support and a very powerful built-in document editor for last-minute tweaks.
- The Bad: The "Pro" features required for clean faxing are behind a relatively high paywall.
5. RingCentral (RingEX) — For Existing Businesses
If your office already uses RingCentral for VOIP calls, don't buy another app. Faxing is already integrated into your RingEX subscription.
- The Good: No extra cost if you're already in their ecosystem.
- The Bad: The app is "heavy" because it handles calls, video, and chat simultaneously.
How to Choose the Right App for You
- How often do you fax? If it’s once a month or less, use mFax.to and avoid the subscription headache.
- Are you faxing medical records? Look for Fax.Plus or eFax — they offer specific HIPAA-compliant tiers. See our best HIPAA compliant fax services comparison.
- Do you need to receive faxes? You'll need an app that provides a "Static Fax Number." Subscription apps usually include this; pay-as-you-go apps are better for outgoing documents.
Step-by-Step: Sending a Fax from Your Android Phone
It’s easier than you think. Using the mFax Android app as an example:
- Open the app and sign in.
- Enter the Number: Type the recipient's fax number (include the country code, e.g., +1 for the US).
- Upload or Scan: Tap the camera icon to snap a photo of your document. The app will automatically straighten the edges and turn it into a crisp B&W fax.
- Hit Send: You'll see a real-time progress bar. Once completed, you'll get a notification and a formal email receipt.
💡 Pro Tip
Always check your confirmation receipt. If the recipient's line was busy, most apps (like mFax) will automatically retry the transmission for you.
The Bottom Line
You shouldn't have to pay for a monthly subscription just to send a two-page document. For the vast majority of Android users, the mFax.to app offers the best balance: zero commitment, high reliability, and a clean interface.
If you are running a clinic or a law firm, go with Fax.Plus. For everyone else? Keep it simple and pay as you go.
