If it accumulates over 1 month, 6 months... over a year, how many important keywords do we forget? Maybe the big direction of your life will change little by little. At times like this, Subrain will act like a milestone in your life. Feel free to write down everything from simple things to do to important keywords about your life. Subrain is a notebook for minimalists who hate complexity. Feel as if you have an extra brain. Just remember these two things: Writing notes and pages containing notes.
