My wife and I have been long time shopper app users. I’m sure we don’t use all the features, but the fact that you can share lists makes it super useful. You can add items on the fly while your partner is shopping, and the items will show up right away as soon as they refresh the app. I recently had an issue with one of the lists, and sent a question about it via email. It took a few days because I’m not a gold member, but the response was a very thorough tutorial. Nice customer support shopper! Shopper is one of my most used apps.
