PilferShush Jammer vs Secure File Manager Beta
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
Secure File Manager Beta
File manager for keeping your files in safe. Features * hiding files * encrypting files * create or extract encrypted Zip files * lock app with password or biometric authentication (optional) * disable screenshots (optional) * disabling thumbnails (optional) * clear cached thumbnails * set destination for creating media files (photo / video) * checksum (MD5, SHA1, SHA256, SHA512) This app is useless if you have a rooted device!
