I have been using my Android phone for about 7 months now. During that period of time, I have found many useful applications and some not so useful ones. This is a great time saver for technical people. This list is by no means complete, I did not include any manufacturing or supplier applications like Digikey. These are tools for the most part. They are the applications that I have found that have made my life easier. I focused on the free applications rather than endorse any paid applications.
This is a list of apps that I found most useful for radio engineering:
- VNC Android. Great remote computer control application that will work with almost any version of VNC server. For logging into servers and workstations to fix things remotely, great time/sleep/gas saver.
- ElectroDroid. App has many electrical engineering calculators; Reactance, voltage divider, resistor ratio, resistor series-parallel, capacitor charge, ohm’s law, resistor of LED, LM317, voltage drop, and battery life. Also includes resistor color codes, SMD resistor color codes, inductor color codes, various pin outs, wire ampacity tables.
- Metrics Converter. A general units converter for metric to standard measurements.
- WiFi Analyzer. Cool application that has a WiFi spectrum analyzer, shows all WiFi channels, signal strengths and router name. Can show an * for open networks.
- Kreac Calculator. A full featured scentific calculator, includes all trig functions, roots, pi, log, e, ln, 1/x, etc. Very handy for some quick figuring on the fly.
- RecForge audio recorder. Can record .wav, .mp3 or .ogg in 8,11,22 or 44 KHz mono or stereo. The audio can be stored in different folders and emailed. Great for quick recordings that can be emailed back to the news room or studio. Sound quality is as good as the microphone on the device. My HTC mic sounds pretty good.
- Google maps. Great for finding things, satellite views, etc. Use Itouchmap via web browser to find coordinates of a location by taping a map.
- Flashlight. Self explanatory, three levels, good for emergency use, but I’d not use it regularly as a work light, it runs the battery down too quickly.
- Audalyzer. Small audio analyzer that works pretty well. If something more is needed, professional versions are available for around $5.00.
- Radar now. Uses GPS location to generate moving weather radar picture. This has come in handy when doing tower work during thunderstorm season. Good for pulling tower crews or reassuring tower crews as needed.
Those are the free apps, there are many, many more available from the app store. As far as iPhone apps go, I just don’t know because I have never owned one.

Great list. Thanks!
Couldn’t find the Kreac Calculator on the Android Market – and web site references don’t indicate that it’s an RPN calc -so I guess it’s not (“=” key not “Enter” key)
For the HP users, I’d suggest the free Droid48 (it’s in the Market) – it emulates the HP48.
As somebody who’s used HP calcs for over 30 years, using a calc without RPN notation is too difficult.
Any other suggestions for broadcast Android apps??
Great ! Very useful tools for radio engineering ! Thanks Paul !
Pham, Thanks, glad you found it useful!
i’m network engineer but i’m studying for wireless networks too. for this i need to build towers to install point to point device to connect two offices. thus i’m looking for some tools to measure the distance and required height for the towers.
therefore i would like to request you to support me to find out the application for it.
looking forward from you.
Ravi, the easiest way to do this is to use a path study program. I have used several Ubiquiti products and have found them to be reliable. There are other vendors like Canopy and Microtik as well.
