Questions

Can I download s0phia ops for free?

SØPHIA is sold by its developer and isn't distributed here. RF Sentinel is the free, open-source option: same category of tool, no payment, no account, and you can read every line of code.

Do I need Termux for RF Sentinel?

No. It's a normal Android app: install the APK, grant Bluetooth and location, tap Start scanning.

Can I run both?

Yes. Both only listen, so they don't interfere, though Android shares one WiFi scan budget between apps (about four scans per two minutes).
