One small task a day. Build small wins and grow your confidence, step by step. One Task a Day is a simple habit-building app that helps you choose just one task for today and record your daily progress. Do you ever feel overwhelmed by too many things to do? Do you blame yourself for not keeping up with a habit? Does a long to-do list make you tired before you even start? This app is not designed to make you do more. It is designed to help you take one small step today, in a way that feels possible. Main Features 1.

Focus on one small step. Small wins, repeated over time, can grow into real confidence. 2. A Gentle New Green Home Screen In version 2.0.0, the app has been redesigned with a calm green visual style. - A home screen that makes today's task easier to see - Clear states for not set, pending, completed, and tomorrow - A softer design that feels comfortable to open every day The app is meant to support you quietly, not rush you. 3. Achievement System Consistency matters. Your progress is recognized with simple achievements. - Track your current streak and total completed tasks - Unlock badges such as First Step, 5-Day Streak, and Weekly Master - Feel a steady sense of progress as you keep going Seeing the days you completed helps you naturally want to continue. 4. Reflection Calendar Look back on your progress with a clear monthly calendar. - See your completion history at a glance - Turn your past effort into visible confidence - Review previous tasks whenever you need to 5. Goal Setting Set a long-term goal or dream and keep it close to your daily task. - Remember your goal from the home screen - Connect today's small task with what you are working toward - Stay motivated by remembering why you want to continue Why One Task a Day Helps Doing one small task every day can support your mindset in three ways. 1. Builds self-efficacy Each completed task gives you proof that you can follow through on what you decided. 2. Reduces decision fatigue Choosing one task makes it easier to stop wondering what to do and start focusing on what matters. 3. Encourages a positive habit of reflection At the end of the day, you can look at what you did instead of only thinking about what you missed.
