The App was TeuxDeux.

I haven't published it publicly yet, as i use it personally and it's a little flakey still, but will look to do in the future once I finish adding all the features.

My version is much more feature rich than TeuxDeux and I made it for Free in Google AI studio over the past two months, between other things. I'd just type a prompt and then go do some other stuff, it has taken quite a lot of revision but I haven't written a single line of code and i've been using it daily to manage my tasks since the start of December.
