> "Apple also says that it’ll use machine learning and Apple Maps to label stores that you use in the app, and use that data to track purchases across categories like “food and drink” or “shopping.” " - I guess this is novel in the United States, but challenger banks like Monzo/Starling have been doing this for a number of years. And even then, I don't think any machine learning is needed here. Monzo use the Merchant Category Code (https://en.m.wikipedia.org/wiki/Merchant_category_code https://en.m.wikipedia.org/wiki/Merchant_category_code) to categorise purchases and public/commercial data sources like Google, Twitter and Foursquare (see https://community.monzo.com/t/where-does-monzo-get-its-icon-images/8385 https://community.monzo.com/t/where-does-monzo-get-its-icon-...) to get merchant locations, "friendly" names and logos.
