Yes I have downloaded and used the Application. It works well considering the phones mic picks up the audible fax signal from the radio speaker.
It would be better if the 3.5mm earpiece phone socket was configured as a mic socket that could be connected to the radio socket direct.
It is worth having as a backup. It is quick to set up and simple to use . But I usually use the pactor 3 modem with sailmail's (email) weather fax software to download and display the weather fax on my laptop.
You still need reasonable HF receiver, plus Pactor modem.
Would be possible to go strait fromRX to laptop audio input with the right software.
As far as know for Weather Satelites, can be recieved like that and a few free different softwares
are available.
My guess teletype signal from synoptic maps, should be processed very similar way.
I have a HF Radio and Pactor Modem.
Its 2016, there has to be a better way. Its all for sale if anybody wants it
Specifically talking HF Weatherfax broadcasts - can you get the synoptic chart in real time (ie. as it is at the minute of receipt or a few minutes prior), or does it mirror the BOM online web site where the chart you see is always delayed by a few hours?
The BOM supply the images that are faxed. The fax takes about 12 minutes to completion and the image appears as the fax is being received. The fax received has the time GMT that it was good for and is usually about 3 hours before.
Dont be confused with receivers that pick up weather satellite directly. These only display cloud images (in short).
If you want the really usefull synoptic fax tune in to get the prognosis ones around 1530 local Sydney time.
In regard to your image on Apple thing, you may need to change frequency on the receiver. My HF tranceiver has the fax frequencies grouped together so once the fax starts I can press channel up or down to get the best reception. The image is only as good as the received signal.
Thank you Ambler, for good info on the broadcast synoptic charts.
Online, I think BOM may supply real time data but only commercially and for a fee. So I guess it's to be expected that the public will only get data delayed by hours.

I visited the Met Service last year in Wellington and was shown over the whole operation including a walk around the roof to see how their instruments pick up what is occuring. The thing that impressed me most is the number of weather stations, satellite data and reports they have to annalyse before they can go public with the actual synopsis of what is happening now and prognosis of what more than likely will happen.
NZ has now got access (and Aus too) of a new weather satellite the Japanese have. It delivers so much information that the Met Service had to buy new super computers to digest, analyse then deliver a result in a reasonable time to be usefull.
In short the delays are still there but getting better. Some things are available imediately on line such as rain radar with time steps so you may see if its coming your way. Other than that I am not sure BOM can give any better service than we already get for free. They offer some specialised forcasting for an ocean passage if you can give them departure time, origin, destination, average speed etc but so does a grib file which I use.
There are so many good books on weather forcasting too especially for sailors.
I have always enjoyed speaking to meteoroligists whenever I had an opportunity such as boat shows.
Cheers
