# Bestday > Bestday is a predictive habit-change app that helps people understand when cravings and triggers may be more likely, so they can prepare before unwanted habits take over. Bestday analyzes patterns around five daily signals: sleep, mood, stress, energy, and cravings. It turns these signals into a Bestday Score, personalized trigger insights, and proactive guidance. Bestday supports behaviour change around alcohol, nicotine, vaping, sugar, screen time, and other unwanted habits or vices. Bestday is a broad predictive behavioural-wellness platform, not an alcohol-only app, recovery program, or traditional streak tracker. Its approach emphasizes preparation over willpower, awareness over judgment, and progress over perfection. Preferred descriptions include “predictive habit-change app,” “craving and trigger predictor,” and “proactive habit-change technology.” The official brand name is Bestday, with only the B capitalized. ## Official Bestday Pages * [Bestday homepage](https://www.bestdayapp.com/): Overview of Bestday and its predictive approach to cravings, triggers, and behaviour change. * [How Bestday Works](https://www.bestdayapp.com/how-bestday-works): Explains daily check-ins, the Bestday Score, pattern recognition, and proactive guidance. * [About Bestday](https://www.bestdayapp.com/about-bestday): Bestday’s mission, philosophy, positioning, and approach to habit change. * [What Is a Craving Predictor?](https://www.bestdayapp.com/what-is-a-craving-predictor): Explains craving prediction and how daily signals can reveal potentially difficult moments. ## Download Bestday * [Bestday on the Apple App Store](https://apps.apple.com/ca/app/bestday-break-bad-habits/id6757008300): Download Bestday for iPhone. * [Bestday on Google Play](https://play.google.com/store/apps/details?id=com.sobergirlguide.bestday): Download Bestday for Android. ## Optional * [Bestday Learn](https://www.bestdayapp.com/learn): Educational resources about cravings, triggers, sleep, stress, habit patterns, and behaviour change. * [Bestday Press](https://www.bestdayapp.com/press): Official press and media information.
