Pen & Paper is a solid 4.8/5 tool.
But you need a 5/5 System.
James Clear's 'Atomic Habits' is our bible. Paper is powerful because it's frictionless. But paper has no memory. It can't tell you that your coffee intake on Tuesday is ruining your sleep on Thursday. Paper is for *recording*; Habit OS is for *understanding*. We take the friction-less philosophy of paper and add the computational power of a neural network.
If you are looking for simple tracking or gamification, Pen & Paper is a solid choice. But if you are a high-performer looking to optimize your cognitive output with data, Habit OS is the only tool built for you.
