Android App for GS-PRO-V5 Spectrometry
Posted: 25 Apr 2026, 03:33
Hello everyone!
It has been a while since last posting, but I wanted to share something I created that might be of interest. I've always wished I could use my probe more like an advanced survey meter for field work. I ended up creating an android app that does just this. It uses inspiration from the Impulse software for pulse shape analysis, but tries to keep things as simple as possible.
Using the app, simply connect your GS-PRO-V5 or similar functionality spectrometer to your android phone using a USB C, like you would with your computer.
Features:
- Histogram (of course) - customizable bin count
- Bin decay - essentially decays counts in each bin by editable speed. This is most useful with a low bin count and helps to keep background down while searching for radionuclides. It basically makes the spectrum very - responsive to new sources in the environment, but obviously not great if you are trying to collect a detailed spectrum with high resolution.
- Basic calibration - rudimentary 2 point linear energy calibration. It always assumes bin 0=0keV and lets you define another peak.
- CPM measurements - displays total CPM and ROI CPM as both numerical values (rolling 5s average) and relative plot (updated every .5 seconds, showing last 30 seconds)
- Audio passthrough - lets you hear the raw audio from the detector, useful for finding hot spots
Disclaimers: I am not a programmer. I'll freely admit that this was pretty much entirely coded with AI. Please feel free to contribute if you have features or bug fixes to add and know a thing or two about android development. Also part of definitively not being a programmer, I don't know nor really care to try to publish it on the google play store. To install it you'll have to use the android studio with your phone in developer mode. It isn't too hard to do. Maybe someday I'll get around to publishing it, but for now I really consider this just a fun little tool that can come in handy with the work I do. Anyways, I hope it helps someone out or sparks some interest.
