Your needs are the brief
Make-It-Yours Planner
Cannot find the planner or app you actually need? Build the first useful version yourself. Choose the sections, rename them and print a planner designed around your real day.
Build a single-page personal planner that works on my phone and prints neatly. First ask what I need to track and what I do not want included. Let me rename sections. Save everything only in my browser and explain the code at a beginner-friendly level.
