*4.4 signal - encrypted messaging cross platform and default SMS client. requires phone number with centralized AWS server... but Snowden did recommend it at one point.
~ silence - same as above but only SMS/MMS, but it uses encrypted sms/mms if both parties use silence (only available on android). No server is used to communicate
signal generator - create frequency
slide - reddit front end, makes dealing with thread much easier
stocks widget - stock price tracker
street compete - push changes to openmaps
suntimes - use location to figure out sun times (rise, gold hour, set, hours total, etc...)
syncthing-fork - syncthing client for android
syncopoli - rsync client for android
tachiyomi - stream or manage downloaded comics and anime
!*4 termux && termux:boot - command line for android, has an extensive package manager and gnu coreutils
~ terminal emulator - raw terminal command line, very few terminals
~ connectbot - SSH client
torbrowser - tor browser for android
torchie - fast flashlight program, requires elevated permissions so audit code and use only on phones you don't care about
transistor - internet audio stream client, for the rare stations that don't work on radiodroid
trifa - tox client for android
unit converter ultimate - great offline tool to convert nearly anything
!userland - app that runs a jailed full instance of Linux if you need native Linux applications and don't have root (termux is a much lighter way of doing this). It has VNC, SSH, and XSDL support (but you need to supply your own applications. Easy Debian, Ubuntu, Arch, Alpine, and Kali setups. (I couldnt get it to function on replicant, appears to hang while starting distro))
vanilla music - good local music player, can play nearly anything and has lyric follow abilities, as well as audio tagger (replicant can't play wav or opus, VLC can play all of these but doesn't act like a music player)
