I believe that overcoming depression involves achieving small goals and objectively reflecting on your emotions by journaling. That’s why I created this app. This app helps you gently record your emotions throughout the day and set small goals to foster a sense of accomplishment. Understand yourself better and take steps toward a positive transformation. This app is designed for everyone who experiences feelings of sadness, just like me. By expressing your emotions in writing and growing through small achievements, you’ll gradually discover a changing, more hopeful version of yourself. Let this app support your small but meaningful beginnings.

Too many things you want to do, but somehow you keep putting them off. Nudidoo is an app that helps you keep going with small daily actions. Made for those who overthink and find it hard to start. “Just one small step today is enough.” Instead of complicated plans, try doing just one small thing today. *This app is currently available in Korean only. ● Create Goals Break down your goals into small, simple actions. ● Be with Nudis When you create a goal, a “Nudi” comes to your aquarium. It grows alongside your dream. ● Daily Candy Check Complete one small action and check it off. Small records build meaningful progress. ● Do It Today, Shine Brighter If you complete today’s task on the same day, you’ll receive a shining candy. ● Decorate Your Aquarium Collect shining candies and decorate your own aquarium. Relax and enjoy the calming underwater atmosphere. ● Complete Your Goal When you finish a goal, send your Nudi off to the sea and keep it as your journey. Recommended for you › You make plans but often put them off › You want to build habits without pressure › You enjoy cute and emotional ways of tracking progress › You have many dreams but struggle to start
