Dopa-writing helps you break the habit of endlessly opening social media, short videos, and games. Pause, write out your thoughts and feelings, and make room for a clearer mind. You don't have to give up your phone all at once. Start by putting the noise in your head into words. Stress, worry, frustration, unfinished thoughts. Write them as they are, for yourself rather than an audience. If you don't want to keep them, let them go without saving. Getting that noise out of your head can give you room to think. A clearer mind makes space for new ideas. When inspiration strikes while you write, capture it immediately with Flash Ideas. Dopa-writing is about more than simply restricting your phone. Turn a device you reach for without thinking into a tool for understanding yourself, thinking deeply, and finding inspiration. Build a new relationship with your phone, one writing session at a time. MAIN FEATURES * Dopa-writing Write down thoughts and feelings as they come, and quiet the mental noise. Shift from endless input to expressing what's already on your mind. * Release Let go of writing you don't want to keep, without adding it to your saved records. * Flash Ideas Capture ideas that appear while you write without interrupting your train of thought. Make space for inspiration as you let go of mental clutter. * App Blocking Use Screen Time to interrupt automatic access to selected apps. Take regular breaks from mindless scrolling and write about what's drawing you back to your phone. * 3 + 1 Intervention Levels Choose Beginner, Intermediate, or Advanced, plus Ultra for complete blocking. Adjust the intensity to suit your goals and gradually change your relationship with your phone. * Reflection Review your character counts, writing time, and how often you interrupted your scrolling. * Dopa Persimmon Grow your own Dopa Persimmon as you keep writing. It grows with your character count, bears fruit, and then...? * Japanese and English Support PRIVACY What you write in Dopa-writing is not sent to external servers. You don't have to post it on social media or share it with anyone. This is a private space to freely express your thoughts, feelings, and whatever is on your mind. PRO The free version includes the core writing experience and app blocking. Dopa-writing Pro unlocks the full experience, including: * More apps you can restrict * Intermediate and Advanced intervention levels * Detailed schedules by day and time * Unlimited Flash Ideas * Instant switching between journaling and Dopa-writing Get more tools to move beyond mindless scrolling and use your phone with intention.
