This is, by leaps and bounds, the thing I use Siri for most frequently.

"Hey Siri, add toothpaste to the shopping list" throws it onto a Reminders list that's shared with my wife, so whoever happens to be at the store next always has an up-to-date list. It's shockingly convenient.

Now, if only Siri were smart enough to let me add multiple items in one go...

My real problem is that i rarely have my phone on me when I'm in the house. That causes issues for an increasing number of things which are phone/tablet only, including the 2FA app for my company's VPN

Hey Siri thankfully works on Apple Watch and iPad as well, so I'm almost always within shouting distance of Siri in my place.

Agreed on the 2FA bit though; would love a good authenticator app with Watch support.

I use Alexa to put stuff on a shopping list all the time. It's probably one of its more useful features for me.

But most of this stuff is things I don't get from Amazon and, if I did, I'd want to check quantities, pricing, etc. For certain types of goods you might want to batch things up an use Amazon Pantry.

I've recently set up an Echo but haven't really explored this functionality yet. As you state most things I want I don't actually want to buy from Amazon. I've been looking into other shopping list skills to use. What I really want is something which synchs with a smartphone app I can use when I'm at the store.

pre-Echo I've been using Evernote for this. I haven't had a chance to try out any of the alexa enabled things but OurGroceries looks to be about what I want.

Echo syncs lists to the Alexa app on the smartphone. The voice recognition works quite well and I find it very handy when I'm cooking and notice I'm almost out of something to add it to my list without having to stop what I'm doing.

Huh, I hadn't noticed the todo list and I always assumed the shopping list was my amazon cart. Neat.
