Reducing drinking, staying sober --- Helps you cut down on drinking and stay sober. --- This app supports people who want to manage their alcohol intake in a healthy way and drink less. The goal is not just to quit drinking completely, but also to help with cutting back and drinking in moderation. You can record both planned drinking (the amount you intended to drink) and impulsive drinking (unplanned drinking). By keeping a diary, you can review your drinking habits, plan alcohol-free days, and find the best way to handle alcohol for yourself. Besides tracking your drinking, the app also helps you manage information about how alcohol affects your mind and body, such as your mood and physical health. This helps you understand the connection between your mood, health, and habits. The built-in supporter feature encourages you in your daily efforts with warm messages, helping you feel proud of your progress in managing your drinking. [Main Features] * Calendar - Set goals, rules, and limits for drinking - Record planned and unplanned drinking - Track medications taken - Log mood, physical condition, and weight * Charts and Totals - View changes in alcohol consumption - Count sober days (days without drinking) - See changes in mood, health, and weight - Check various totals * Supporter Feature - Plays 112 types of encouraging voice messages - Choose from 2 character supporters * Paid Features - Remove ads - Import/export data - View charts for periods longer than 3 months [Credits] English voice - ondoku3.com Japanese voice - VOICEVOX:SHIKOKU Metan - VOICEVOX:KURONO Takehiro
