What app would I use to toggle a curtain with a single button?

[frmWink2Hubitat]

In rule machine, it only says open and close

We need a little more information. What device driver are you using? What button are you using? If the driver reports the state of your curtain (open or closed), then a simple "if" statement would either open or close your curtain based on current state.

Generic window shade. I want the middle round pico (3) button to toggle it. Thank you

You could use button controller and the conditional action option @Pantheon suggested, checking the current state of the curtain and doing the opposite command,

Or a very simple "toggle" command that would either open or close based on current state. That is if you only want fully open or fully closed.

If (curtain is open) {
   Close curtain
} else {
   Open curtain
}

There is no toggle command I can find

[Pantheon]

I was not sure about a toggle command. Then @lairdknox 's code is my choice.

[SmartHomePrimer]

It exists for switches. Maybe not showing because of the device type. The IF > Else option shown should do the trick if you cannot choose Toggle Switch.
