How autostart Interactive program at boot before tty appears

Question

I'm coming from Ubuntu to Arch Linux, I'm trying to autostart an interactive program written in C++ at boot before tty1 appears.
I have created a file called /etc/systemd/system/myapp.service with the following contents:
[Unit]
Description=myapp
[Service]
Type=oneshot
ExecStart=/home/xxx/myapp.exe start
StandardOutput=tty
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target
And then run
sudo systemctl enable myapp
Unfortunately, it does not work as expected:
1. I can't interact with myapp
2. I do not want tty1 to appear until the program ends

thank you . thank you . thank you .
the secret thing in magic line `StandardInput=tty`
my final  /etc/systemd/system/myapp.service
contents:
[Unit]
Description=myapp
After=sysinit.target
[Service]
Type=oneshot
StandardInput=tty
StandardOutput=tty
RemainAfterExit=yes
ExecStart=/home/xxx/myapp.exe start
ExecStop=/home/xxx/myapp.exe stop
[Install]
WantedBy=multi-user.target
AND i disable tty1
sudo systemctl disable [email protected]
Now tty1 is my app (-:
Another problem )-:
ExecStop=/home/xxx/myapp.exe stop
not working, i want run myapp with stop parameter on shutdown/reboot system
thanks for ( Trilby, progandy )
