About

DuoMode

Features
Read full description

DuoMode is the app for habits, challenges, and routines to do as a duo or solo. Build healthy habits, hit deadline-driven goals, organize your daily routine, and log your mood in a journal, all in one productivity and accountability app. Invite your partner, girlfriend, boyfriend, a friend, or a family member and turn goals into achievements together. Why as a duo? Because commitments are easier to keep when someone else is involved. Studies on habit formation show that having an accountability partner greatly increases the odds of staying consistent. DuoMode turns that into a product: challenges for two, a shared routine, and a mood journal that brings couples closer. CHALLENGES WITH GOALS AND REWARDS Create challenges with a deadline, daily check-ins, day streaks, and milestones with rewards. Choose Duo mode to do it with your partner, Solo mode to grow on your own, or Squad mode to challenge a group of friends. Set a weekly target, a motivational message, a daily reminder, and a surprise reward. Track each person's progress, react to your partner's check-ins with emojis, and log photos as proof the habit was completed. ROUTINE AND DAILY CHECKLIST Organize your day-to-day tasks in a shared checklist: home, work, study, health, finance, pets, and kids. Set the frequency (every day, weekdays, every N days, once a week, or multiple times a day), time, and time of day. Split household chores with shift rotation: my turn, partner's turn, or automatic rotation. Ideal for home organization, fair division of chores between couples, and family routine management. MOOD JOURNAL Log how you felt each day with a mood emoji, formatted text, and photos. Track your emotional well-being on the mood calendar and, if you want, share your journal with your partner to strengthen connection and communication in the relationship. Privacy first: each entry can be private or shared. FEATURES THAT HELP YOU STAY CONSISTENT Personalized reminders and notifications so you never miss a habit. Human-friendly streaks: one missed day won't break your sequence. Retroactive check-ins to log past days. Home screen widgets showing routine and journal progress. Invite by code or link to connect with your partner in seconds. Dark mode, a simple interface, and automatic sync across devices. WHO DUOMODE IS FOR Couples who want to build habits together and organize life as a duo. Friends who want to stop procrastinating with a 30-day challenge. Anyone looking for a habit tracker with real motivation. Anyone who wants to build a morning routine, workout routine, study routine, or reading routine. Anyone looking for an app for goals, self-care, discipline, and personal development. USE CASES Work out at the gym 4 times a week with your partner. Drink more water, meditate, read every day, or sleep earlier. Study for an exam or learn a language with consistency. Split the housework without arguing. Log gratitude and mood daily. Save money with a 90-day challenge and a reward at the end. Start for free: create your account, set up your first challenge or routine, and invite your partner. Download DuoMode and build habits and routines, together or on your own.
