Depends on what exactly you want it to do.  If you want the app to do
something other than exit on receipt of SIGINT, you need to somehow
tell the app to do something different.

If you want the app to exit but ssh to keep the shell up it's possible
although a bit convoluted: you need the remote login shell to kill its
child on receipt of SIGINT but not die itself, then invoke an
interactive shell for you to interact with, something like:

$ ssh -v -t localhost "trap 'kill -INT -$$' INT; sleep 60;
PS1='remoteshell$ ' sh -i"
[...]
^Cremoteshell$ exit
[...]
debug1: Exit status 0

The trap sends a SIGINT to the process group of the login shell which
includes the "app", which exits, causing the login shell to start
another (interactive) shell.
