Need an app for change Typed charecter from on keyboard layout to another

[karen841]

I have two keyboard layout and I know how change between them
but always I am in EN for example and I think it's on FR and ّّI type,
after some word I understand it was EN and I should type all of them in FR again.

In PC with some App like "Comfort typing" it's easy, when you find you are in wrong keyboard layout just with a shortcut you can change your typed character to second keyboard layout.

is there any app or way in Mac for this?
