I recently discovered an IMSI-catcher app on the F-droid market for Android. It's called Android IMSI-Catcher Detector and you can easily find it in the Security category if you filter by it in the app. For some reason, I can't browse for it on the site.
The project is in alpha stage and seems to be this one here:
I hope to see more people working on this, though. In fact, I wish Google, Apple and Microsoft would add protections against IMSI-catchers by default in their mobile operating systems. After all it's already a known privacy issue affecting millions [1], and it seems not just in US either. They can't continue to pretend it doesn't exist anymore.
They spotted the (presence of) IMSI-catchers with a GSMK Cryptophone, apparently. I actually come to HN just now, to see if their product had been shredded, I mean carefully analysed, here earlier ;-)
"xgoldmon is a small tool to convert the messages output by the USB
logging mode of phones with Intel/Infineon XGold baseband processor
back to the GSM/UMTS radio messages sent over the air so you can watch
them in e.g. Wireshark in realtime."
The idea here being that if you can see diag from these phones you can watch for suspicious things like zero length SMS and so on ...

There's also this paper on making IMSI-catcher detectors:
