PilferShush Jammer vs Warden
Side-by-side comparison of two open source alternatives
PilferShush Jammer
Features a passive jammer technique that engages the microphone thereby blocking other apps from using it. But does NOT listen to or record any of the audio from the microphone. It uses 0% CPU and no noticeable battery use. However is not intended to be left on permanently due to the variety of triggers that can cause audio_focus_state changes (VOIP etc). Also features an active jammer that emits tones constrained to the NUHF range of 18 kHz to 24 kHz range. User determined carrier frequency and drift limits with rate for random tone emissions depending on the device capabilities. For instance 20000 Hz carrier, drift limit 1000 Hz and rate slow - will output random frequency between 19 kHz and 21 kHz approximately every second. Audible artifacts are present during the NUHF tones but this may be changed in a future release. Experimental white noise output may not be very effective at blocking and is a somewhat annoying sound. The device speaker output may not have enough amplitude to block unwanted NUHF signals - testing will determine. * Manual start * Notification post when running * Auto stop and restart when telephony interrupts * Currently relies on audio_focus_state changes for auto-switching * Active jammer
Warden
Warden helps you keeping trackers and loggers at bay, as well as getting rid of bloatware.Warden has a static curated list of known trackers (Exodus Privacy), each app’s dex file is read to retrieve the class names, these class names are then matched with the signatures of known trackers & loggers to find them.Loggers in the context of Warden means all utilities which are used to log user activity on an app or logcat in general. Not all loggers are evil. But few logging tools like ACRA, xLog are very powerful tools that can send user data to devs without user’s consent. So do read the app’s Privacy Policy, beforehand.Warden further provides a profile based de-bloater where a profile is created in a format specified as in this sample scripts You need to place this profile/your custom profile at "ExternalStorage/Warden/Profiles" to make them appear in app.
