Compute distance and bearing using Maidenhead location. This was originally intended for use by amateur radio operators who participate in microwave communications however it can be used by any ham in order to determine a distance and bearing to another radio amateur. This version adds a map of the source and target along with a pin annotation and an overlay identifying the six-digit grid area. If a user touches an empty location on the screen for one second a new annotation is added at that spot identifying the grid. Any user-added annotations are removed if the map view is exited and re-entered.
RST Scope
This utility app provides spectrum scope and waterfall displays for amateur radio operators. It enhances radios lacking these features by analyzing microphone input, allowing for clear distinction of Morse code and detailed audio frequency visualization.
- Spectrum scope and waterfall display
- Morse code distinction via FFT
- Adjustable waterfall speed
- Adjustable audio input level
- Switchable display band (wide/narrow)
- Display pause function
- Recording and playback of input sound

This is an app for amateur radio operators with a narrow band of audio frequency, spectrum scope & waterfall display. You can get a rich display by microphone inputting the speaker output of a radio that does not have a spectrum scope or waterfall function. The FFT allows you to distinguish between the dot and dash of Morse code. [function] 1. Ability to change the speed of the waterfall 2. Ability to adjust the level of audio input 3. Function to switch the display band between wide and narrow 4. Display pause function (pause / cancel by touching the screen) 5. Function to switch the cross hatch ON / OFF by longTap 6.

Verdict
The clearest difference is rating: RST Scope at 5.0 against DBHamPlus's 4.0. RST Scope also leads on update cadence (every 3 days vs every 24 months). DBHamPlus's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases and device support there is nothing between them.
