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 displays the following important solar and geomagnetic readings: Solar Flux A-Index K-Index Sun Spot Number X-Ray Flux levels X-Ray flares Solar Wind Earth's Magnetic Field Proton and Electron Flux levels Radio Blackout conditions Geomagnetic Storm conditions Solar Radiation Storm conditions Graphs of x-ray flux readings from the GOES satellites may also be displayed. The following radio propagation reports and forecasts are available: WWV Geophysical Alert 27 Day Space Outlook 45 Day AP Forecast Geomagnetic Data Daily Geomagnetic Data Daily Particle Data Daily Solar Data GEOALERT Daily Magnetometer Analysis Reports Hourly Magnetometer Analysis Reports Predicted Sunspot Numbers and Radio Flux Report of Solar-Geophysical Activity Solar and Geophysical Activity Summary Solar Region Summary Weekly Highlights and Forecasts Current Space Weather Indices Space Weather Event Reports Daily Space Weather Indices Summary of Space Weather Observations 3-day Space Weather Predictions SEC Space Weather Alerts In addition, 21 maps of current D Layer Absorption levels are available for display.

Verdict
The clearest difference is update cadence: RUMlogNG2Go at every 4 weeks against DX Toolbox's every 9 months. RUMlogNG2Go also leads on rating (4.7 vs 4.4) and chart position (#193 vs unranked). DX Toolbox's advantage is price ($3.99 vs $4.99) and iOS requirement (6.0 vs 17.6). On ads, in-app purchases, monetization model and device support there is nothing between them.
