User verdict / 100 High confidence Divided

Fax Burner is praised for its ease of use and free tier for occasional faxing, but many recent users report significant issues with fax transmission failures, poor quality, and restrictive free page limits that contradict the app's 'free' claims.

Recurring themes

Ease of Use positive
Many users consistently praise the app for being super easy, quick, and straightforward to set up and send faxes.R1R3R4R6
Free Tier Limitations negative
Many users express frustration and feel misled by the 'free' claims, as the free tier is limited to a very small number of lifetime pages (often 5), after which a costly subscription is required. Some users also report that failed faxes still count against their free page limit.R68R210R320R266
Fax Reliability & Quality negative
A significant number of recent reviews report that faxes fail to send or be received, even after multiple attempts, rendering the app useless for critical documents. Additionally, the quality of sent faxes is frequently described as horrendous, blurry, or illegible, especially when using photos of documents.R19R216R298R274
Document Upload Options negative
Users are frustrated by the limited options for uploading documents, which are typically restricted to taking a picture, uploading from the photo library, or Dropbox. There is a strong desire for direct support for files from iCloud, Google Drive, or PDF documents.R55R213R237R223
Bugs & Support negative
Some users report bugs such as the app crashing when adding pages, losing a reserved fax number, or the 'reserve a new fax number' button becoming non-functional. There are also complaints about a lack of support for free users and unresponsiveness from the developer. The developer's notes mention "Bug fixes for sending faxes," but recent reviews still report sending failures, indicating the fixes may not be comprehensive.R223R16R461R479

Who it's for

This app is for individuals who need to send a very occasional, single-page fax and are comfortable using photos of documents, as the free tier is extremely limited R320. It is not for users who need to send multiple faxes, require high-quality document transmission, need to send faxes internationally outside of the US/Canada, or expect reliable customer support without a paid subscription R210R48R403R404.

Evidence note: The recent reviews skew significantly more negative than the lifetime rating. While many recent reviews still praise ease of use, a substantial portion highlights critical failures in fax transmission, document quality, and dissatisfaction with the free tier limitations, which contradicts the high lifetime rating. The trajectory suggests a decline in recent user satisfaction.

  1. [R1] 5/5 · US easy: super easy! no hidden fees
  2. [R3] 5/5 · US Easy to use: Super easy to use! Would recommend
  3. [R4] 5/5 · US Super Easy: That was free and easy, wow
  4. [R6] 5/5 · US Quick fax sent from IPhone: Easy to use and quick to send. Good service.
  5. [R12] 5/5 · US Was actually free: Super easy to setup up and did exactly what I needed it to do!
  6. [R15] 5/5 · US That was so easy!: I needed to fax 5 pages of very important stuff to a health care office that wanted to double bill me. I was told I could only fax or drop my stuff in their office. I rarely fax so I do not want to pay subscription. Getting it done free was a bonus. Uploading was easy.
  7. [R18] 5/5 · US So easy to use in love: Literally was super easy to use. Entered the fax number smoothly. Attached my document flawlessly. I am very thankful such an app exists! First 4 pages are free.99 Literally life saver!!! Thank you!!
  8. [R19] 1/5 · US Doesn’t work: I tried using this app it didn’t work for me
  9. [R216] 1/5 · US SCAM: Should be 0 stars. Absolutely terrible app. Does not receive fax. It does not send fax. It is a scam. I have no idea how they have a 4.9 star rating. They must scam Apple too.
  10. [R298] 3/5 · CA I keep getting an error code: The app itself was really easy to set up, but when I went to send the fax I created it gives me an error code it says error while sending fax, log in error? I am logged in though I’m not logged out. I wouldn’t have wrote this here but I can’t find a place to contact the developer.. hopefully they see this!
  11. [R274] 1/5 · CA Fax: Finally decide on an app then when setting up I get an error code 500 message….ugggh back to drawing board
  12. [R68] 2/5 · US NOT FREE: I wish these apps would be truthful from the jump cause only the first 5 pages are free there is no Free faxing Send & Receive like it says under the title
  13. [R210] 1/5 · US ALL READERS OF REVIEWS READ HERE: 5 maximum outbound faxes until you’re forced to pay $15 a month. To send a fax. Funny, isn’t it? Delete this app and write the same review you see here. Help yourself out.
  14. [R320] 3/5 · CA It works…: If you need to send a one time fax of less than 5 pages, I recommend this app. You only get to send 5 pages for free in your lifetime! That is a ridiculous limit. Be careful and edit image contrast or it will not show up properly in the fax app. If you’re willing to send the $130 CAD annual subscription fee then you will most likely love this app. Easy to use.
  15. [R266] 2/5 · CA The way I see it: Great service but would like to see 10 pages sent for free. 5 pages is too small a size hope this helps
  16. [R48] 1/5 · US Misleading, horrible quality: The fax number that the the app assigns you is not the same number that it sends your fax from 🤦‍♂️. The quality of scans after faxing were absolutely horrendous, the pictures that I took were very legible with good lighting so not sure what happened. As far as I could tell, no option to delete the built in cover page. Only 5 pages for free, straight to the pricey mon
  17. [R213] 3/5 · US Quality isn’t great: I don’t know about the paid versions but the quality of incoming fax is not very good. It was readable but not great. Sending a fax was pretty easy except I couldn’t upload doc from files I had to either upload a picture, take a picture or upload from Dropbox. All in all, I only needed it for one incoming and one outgoing fax and it seemed to have worked fine for my task.
  18. [R337] 1/5 · CA Terrible Print Quality: The app is easy to use however taking photos of the documents made it so dull nothing can be read. Now I have to re-send. Waste of time.
  19. [R398] 2/5 · CA Unprofessional and blurry: The fax that I sent was so blurry it was almost unreadable. Also the cover page makes it look unprofessional.
  20. [R55] 3/5 · US Need more options: I hardly use Dropbox, maybe add other options like upload from iCloud or computer or Evernote
  21. [R237] 3/5 · US Files on iPhone: Why can’t I select Drive files on iPhone to fax? I scanned the document but couldn’t use it. Had to settle for a lousy picture instead.
  22. [R223] 1/5 · US Broken on first try: I know it’s free but, could it at least work?? I created an account with my email, reserved a fax number, tried to compose a fax. The app crashed when trying to add the page I need (which for some reason doesn’t let me grab from the files app. images or Dropbox only… really dumb!). I reopened the app and then it refused to let me reserve another fax number. No error messages.
  23. [R16] 4/5 · US Terrible bug: If you download the app and are assigned a fax number for 24hrs. If you exit the app with the 24 hrs and then go back in the fax number you will be gone and when you go to press the “reserve a new fax number” button, it will be non functional. I had to log out and log back in, in order to see my reserved fax number again.
  24. [R461] 3/5 · CA Can't have fax number at the first time: I can't have the 24 hours fax number at the first time, have to close the application and reopened.
  25. [R479] 3/5 · CA No doc or pdf support :(: You should add a dropbox support to access .doc or .pdf files because faxing a photo of a document causes bad quality. The rest of the app works well (it crashes when the fax is sent but the delivery is still successful).
  26. [R403] 1/5 · CA Not internationally: No country Other than US and Canada. Deleted after download and tried to send document. Waste of time. Should say so on the description page.
  27. [R404] 1/5 · CA Zero support for free user: Sent two faxes. None have gone through. Why would I upgrade my service to get tech support when it doesn’t even send a simple one pager?
  28. [R444] 1/5 · CA Could not send fax to a Canadian fax number: Everything worked as promised until I actually tried to send the fax. I got this message by return email: "Hello,We do not allow faxing to 867668XXXX." (Number x'd out by me.) So I ended up with another fax app and sent a fax to the same fax number without difficulties.
  29. [R448] 1/5 · CA Pourquoi un numéro américain ??: Triste et pas utile au Canada et Qc !
  30. [R485] 1/5 · CA Didn't work: I wanted to try it but didnt work, it's not free at all , if you read the policy it sounds that you can send 5 free faxes a month but it seems to be 5 life time!! Even though I couldn't use anyone even to try.
