I’m still pretty new to this app and I’m still discovering features—using weights for produce and discounts are nice features I’ve recently tried—but so far this app is really powerful and easy to use. I might look like a dork using it in the store, but the truth is I struggle with mental math (esp. when sales tax, discounts, or quantity by weight are involved) so I’ve always just guessed at my running total while shopping—not ideal for keeping spending under control. My wife is a bit of a Luddite and is also very good at mental math, so we haven’t collaborated on a list yet (maybe someday) but for my own use, this is an excellent app.
