Looking for a Checklist app

[dpw09]

Here is my dilemma, I have a DTEK50.
My wife has the new Pixel 2 and is in love the Google Assistant.
We also just bought an Amazon Echo Dot.
The wife want to voice activate her shopping checklists.
She wants to be able to dictate the list on her phone with assistant or while in the kitchen to alexa. I need an android app that is compatible with alexa skill and assistant. So far the only one I can find is "out of milk" but unfortunately has not released their skill for Canada. I'm not having any luck convincing them to do so either.
I'm looking for recommendations of other options.

As far as I've been able to find, in years of looking, there's nothing available. Checking things off with your finger, yes. Telling Alexa or Dot to check things off? No. (And I've tried Out of Milk - even for its intended purpose, food shopping lists, it's not one of my favorites. I've ended up just using a text editor to modify a text file I have on a home screen to add and delete items. And that might work vocally.)
