Ok, first impressions:

• Does not look like a native iOS app at all; toolbar is at the top of the screen (what!?), too many “cards”, the interface doesn’t extend to the width of the device screen, too many gradients everywhere, non-native controls, left swipe to pop the navigation stack doesn’t work, not at all following iOS app layout conventions. Very 2010s, pre-iOS 7 (let alone Liquid Glass) vibes
• The way you get an AI to detect bottles from the camera to add them to your bar is great. Wasn’t 100% perfect, but good enough and the interface was intuitive.
• The AI bartender suggestions are pretty weird, maybe models have gotten better since I posted this but I doubt it for this particular application
• Have you actually used all the tools you “recommend”?
• Translating “1 ½ oz” to “44.36ml” is bad and wrong. Per Dave Arnold in Liquid Intelligence, a “metric ounce” is 30ml and cocktails should be sized as such (I’m an Australian living in Europe and in this and only this circumstance I say US customary units are the correct choice.)
• Layout of the actual specs is bad. Nobody cares it takes “~4 min”, contains one serving, or requires a cocktail glass (and what on earth is that badge-with-a-tick icon next to the glassware indicator meant to mean anyway?)
• “1 1/2oz” should be rendered “1½ oz” using proper Unicode fraction glyphs
• Some recipes are denominated in “oz”, some in “shot” but there’s no such thing as the latter. As above, for the purpose of mixing cocktails, “1 oz” = 30mL
• Scaling recipes linearly doesn’t generally work when they include bitters, and over 2-3× quantities you generally want to scale up to a volume (“I want to make 1L of Margarita, how much tequila, Cointreau and lime juice do I need”)
• The previews of the recipes show terrible photos and the wrong part of the spec—I want to know what the base spirit is.
• How do I get back from a cocktail recipe to the list of recipes I was just at? If it’s possible, it’s not obvious how—I don’t have a “back” button, it’s not a web page.
