User Reviews

HF Weather Fax is praised for its core ability to decode HF weather fax signals into readable maps and its support for SSB/FSK, plus helpful features like pinch-zoom, global frequency schedules, and decent developer support. However, a sizable portion of reviews cite unreliable results (white dots or unusable images) and unclear instructions, which lowers perceived value. Overall, it’s attractive for radio hobbyists with good signal, but it’s not consistently dependable for everyone.
Pros
  • Decodes HF weather fax signals into readable weather maps and charts.
  • Works with SSB/FSK receivers and can be used with simple headset-to-mic setups.
  • Readable, zoomable maps on iPhone/iPad with pinch-zoom and grayscale/black-and-white display.
  • Includes a global schedule of frequencies and lets you save faxes for offline reference.
  • Strong developer support and generally reliable performance when the signal is good.
Cons
  • Unreliable decoding and unusable images in many setups (reports of white dots, blank screens, or no image).
  • User interface and instructions can be unclear or lacking, with mentions of confusing controls and missing guides.
  • Perceived poor value for money due to inconsistent performance and reports that the app is not worth the price.

I had high expectations. The reality is that it is a great idea, but does not really work in real life. Aside from other noises, after everything is quite it still bring a very poor quality, non synchronized fax view that is useless. I wish it would work as I wanted it as a backup for my HF SSB computer weather fax program. I gave it two stars with hope that sometime in the future it will be tunes and synced better

This decodes HF FAX signals, hence the name. It will not do satellite images, nor does it claim to.

Just remember the schedules are in UTC time, during summer that isn’t the same as nearby London time. Had me scratching my head but not any fault of this great app.
