Screenshot Aclock is a another clock program, but this time it's an analog clock.

To compile it on Termux you'll need to downloaded the source.

wget https://raw.githubusercontent.com/tenox7/aclock/master/sources/aclock-unix-curses.c

You'll also need the ncurses-dev package.

apt install ncurses-dev

Now you simply have to compile it.

gcc aclock-unix-curses.c -o aclock -lncurses -lm

After that you can simply run it with ./aclock.
