As answered by people managing JavaScript Operator Lookup and AlcoList.
AlcoList's answer:
AlcoList is built around calm awareness instead of guilt or pressure. It helps people understand drinking patterns with clear totals, trends, breakdowns, spending, and personal guidelines, without turning the app into a recovery program or a judgmental habit tracker.
AlcoList's answer:
AlcoList is simple, private, and focused on everyday tracking. It is made for people who want to understand what they drink, when they drink, how much it costs, and whether their habits are changing over time. It works across iPhone, iPad, and Mac with a clean interface and practical analytics.
AlcoList's answer:
AlcoList is for people who drink alcohol but want more awareness and control. It is useful for mindful drinkers, people reducing alcohol, people tracking spending, and anyone who wants clear personal data instead of guessing from memory.
AlcoList's answer:
AlcoList started from a simple problem: alcohol habits are easy to underestimate when they are spread across casual evenings, weekends, social events, and “just one drink” moments. The app was built to make those patterns visible in a calm, practical way.
AlcoList's answer:
Native Apple stack: Swift, SwiftUI, SwiftData, CloudKit/iCloud sync, Charts, and StoreKit. AlcoList is built for iPhone, iPad, and Mac.
