SØPHIA (also searched as s0phia ops, SophiaOps, SØPHIA LITE, SØPHIA CIVOPS) is a closed-source passive BLE and WiFi recon app for Android, sold by its developer DetecX. RF Sentinel does the same kind of passive signal recon for free, with its full source on GitHub, and adds police-specific detection on top.

Questions
Is there a free version of s0phia ops / SØPHIA?
SØPHIA is sold by its developer and isn't distributed here. If you're looking for a free app that does the same kind of passive Bluetooth and WiFi recon, RF Sentinel is free and open source: no payment, no account, and every line of code is public.
What's the best open-source app like SØPHIA for Android?
RF Sentinel: a GPL-3.0 Android app with a radar view, passive BLE and WiFi scanning, tracker follow alerts and hidden-camera checks like SØPHIA, plus sourced police body cam, Flock ALPR, patrol-vehicle, Remote ID drone and fake cell tower detection, an offline camera map, Android Auto and ESP32 support.
Can I run RF Sentinel and SØPHIA together?
Yes. Both only listen, so they don't interfere, though Android shares one WiFi scan budget between apps (about four scans per two minutes).
