Insular vs PilferShush Jammer
Side-by-side comparison of two open source alternatives
Insular
Insular is a FLOSS fork of Island. With Insular, you can: Isolate your Big Brother apps Clone and run multiple accounts simutaniuosly Freeze or archive apps and prevent any background behaviors Unfreeze apps on-demand with home screen shortcuts Re-freeze marked apps with one tap Hide apps Selectively enable (or disable) VPN for different group of apps Prohibit USB access to mitigate attacks with physical access If your device is incompatible or not encrypted, you can skip this limitation manually. Please refer to the XDA post for details. To uninstall and remove Insular completely, please first "Destroy Insular" in Settings - Setup - Click the recycle-bin icon besides Insular. If you have already uninstalled Insular app, please "Remove work profile" in your device "Settings - Accounts". PERMISSIONS DEVICE-ADMIN: Device administrator privilege is required to create the Insular space (work profile), which serves as the fundamental functionality of Insular. It will be explicitly requested for your consent. PACKAGE_USAGE_STATS: Required to correctly recognize the running state of apps. It will be explicitly requested for your consent. We will never collect any data and Insular have no Internet permission. Please read our privacy policy for more details. Differences from Island all blobs (gms, crashlytics, etc) are removed to comply with F-droid's policy Internet access of this app is removed because we just don't need it All features are preserved and will be synced upon Island's updates
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
