Are you a ham radio operator or shortwave listener, in need of up to date propagation information and solar conditions? DX Toolbox features several propagation forecasting tools, allowing you to quickly and easily estimate current HF (Shortwave) propagation conditions between any two locations in the world, and is ideal for the ham radio operator, shortwave listener, or other radio enthusiast.
Radio propagation conditions can also be estimated between any two points on the Earth. Graphs of these conditions can be generated for a given frequency or time, and MUF/LUF graphs can also be displayed.
A grayline map of the world is also available. Radio propagation between locations within the grayline region of the world is often greatly enhanced. DX Toolbox's grayline map makes it easy for you to determine where those locations are. Grayline propagation has been used by expert radio operators and DXers for years to catch elusive stations. A plot the great circle (both short and long) path between your location and another station is also displayed, as well as the beam heading and distance. The location of the currently transmitting NCDXF/IARU beacon can be displayed on the map as well.
The propagation map displays the areas of the world where your signal can be heard (or a signal can be heard from), based on the frequency, transmitter power, and current solar flux, date, and time.
Maps showing ionosonde plots of foF2, foEs, and hmF2 data from various locations around the world are available. The MUF and skip zone can be calculated based on foF2 and hmF2 values.
Aurora prediction maps for the northern and southern hemisphere are available.

DX Toolbox FAQ
Is DX Toolbox free?
Yes, DX Toolbox is completely free and it doesn't have any in-app purchases or subscriptions.
Is DX Toolbox legit?
🤔 The DX Toolbox app's quality is mixed. Some users are satisfied, while others report issues. Consider reading individual reviews for more context.
Using a new IPhone 16… The app has a lot of links to solar data. Half of the info links don’t download. If the data does download, it takes a long time. ( cell network connection)
The graphs and pictures are small and hard to see on my IPhone.
The link labels could be little more informative as to the data origin.
Some of the downloaded data pages display about half of the document and will not scroll down to see the remainder of the document.
Some graphs’ X and Y axis are not labeled.
Some of the data, of course is useful. But, you have to hunt and peck through the copious menu items to determine which menu item will download or provide the common ham operator useful displayed data.
Overall, I use it occasionally. However, it’s just as convenient to go to the NASA’s Space Weather website.
Doesn’t work anymore
I can’t get most of it to work anymore. None of the maps work. Only the home page. What gives?
Great for someone learning
I started keying when I was 13 years old I will be 51 this year but I never gotten this serious about amateur radio, my past experiences enabled me to pickup very quickly on this app and I find the propagation map to be extremely accurate for all frequencies,
I tested the map trajectory on frequency 27.385 LSB and I got skip from those areas the map predicted, your transmission wattage is also taken to determine proper propagation prediction from app.
Get a good SWR Meter to ensure your getting out !!!
Call Sign: 1771AF ( self appointed not official yet ) ch 38 LSB 27.385
A Must-have...
The iPad version is extremely useful, especially when mobile Dxing. Love it.
Needs work
The graphs do not show values in the x axis. Location entry for stations do not support a grid square. Did this app make it through testing for iphone 12? I am requesting a refund.
Solar image support
With latest IOS update solar images no longer work or are coincidentally no longer a available. Great app other wise.
2021. Woefully outdated.
Needs an updated. Wonky interface, requiring tapping through rows, unsaved settings, strange UX.
Please update.
Almost perfect
This is a wonderful tool at a great price. I’m glad I found this app. To make this app even better, I think there should be an option near each parameter where I can tap for tips and definitions. I’m a newbie at this stuff, and it would be great to get in-app help regarding, say, how to interpret the A index, or whether a solar flux of 70 is good or bad, for example. Also, a dark mode would be fantastic.
Some data issues
This app hasn’t been updated in a long time and I’ve noticed that the solar data it uses isn’t up-to-date. That causes the calls to be wrong. I’d love to see the developer update the software connection to the data sources. Thanks.
Really like this app.
Very comprehensive set of tools for understanding propagation.
