About ChainBud: Habit Tracker Buddy
Build habits, grow your cute companion, and take care of yourself. ChainBud turns the "Don't Break the Chain" method into a cozy virtual pet adventure. Every day you complete a habit, a new link is added to your chain and your buddy grows. Stay consistent and watch them evolve through 8 levels. CHOOSE YOUR BUDDY - Bun-Bun (Bunny): soft and cheerful, great for daily tasks and creative hobbies. - Leo (Lion): brave and strong, perfect for workouts and focus goals. - Bambu (Panda): calm and mindful, for meditation and self-care. - Kitsune (Fox): quick and energetic, for mornings, steps and early wake-ups. - Hootie (Owl): wise and curious, for study, coding and reading. - Barnaby (Bear): steady and protective, for your toughest willpower habits. EARN STARS, DRESS YOUR BUDDY - Every completed chain earns stars. Your first 3 days pay double! - Spend stars in the shop on hats, glasses, crowns and other cosmetics placed around your buddy's frame. - Play a quick Star Catch round as a reward for completing chains. FAIR, FORGIVING STREAKS - Weekly targets: choose how many days a week counts, the rest are rest days. - Recover yesterday if you forgot to check in. - Streak Shields and vacation mode protect your progress when life gets busy. TAKE CARE OF YOURSELF - Mood jar: log your mood each day and see how your month felt. - Cycle tracker: log periods, flow, spotting and notes. ChainBud learns your average cycle and gently shows the next expected period and when it is late. Spotting is tracked separately and never counted as a period. (Not a medical device and not for contraception.) MORE - Weekly overview of all your buddies, best streaks and heatmaps - Gentle daily reminders - Home screen widget - Optional cloud backup with Apple or Google sign-in - Available in 13 languages ChainBud Premium (optional subscription) removes interstitial ads and adds 3 Streak Shields per week, vacation mode, unlimited Star Catch rounds, exclusive cosmetics and all mood × habit insights. - Terms of Use (EULA): https://yigitemreturkkan.com/chainbud/terms - Privacy Policy: https://yigitemreturkkan.com/chainbud/privacy
