About

Columnam

Columnam - The Self Actualization App With Columnam, you can produce greater work in a more efficient manner, with an improved understanding and appreciation of whatever it is you do. Columnam trains users, through highly structured work sessions and psychological techniques, to enter the state of focus on command. By tracking users' focus and work habits, it creates a personalized system of improvement that includes analytics to display those habits, and challenges to improve them. That improvement is made extremely achievable by the rigid structure of the program. Our community provides a social environment of ambitious learners who are overcoming, or have overcome, the same challenges that the user is facing. By learning to focus on demand, users will engage with their work on a deeper level, deepening at the same time their appreciation of that work, as its virtues are viewed with a clear eye. As a result, users of Columnam will produce greater work in a more efficient manner, with an improved state of mind and relationship with their work. Learn to Focus Deeply: Train deep focus while doing your work/schoolwork. To properly train this skill, we split your work sessions into two separate categories 1. Deep Work: When you want to deeply engage with a task. During these sessions, you go through a series of psychologically proven methods to induce a state of deep focus and reduce split attention. Apps are blocked and a longer period of time is dedicated. Analytics are collected on your habits. 2. Other Work: When you need to focus, but don't need to engage deeply. A lighter focus ritual is performed and app blocking is less strict. Analytics are collected on your habits. Seamless Scheduling: Easily create your daily work schedule with our framework. Track Your Habits Automatically: Columnam automatically collects 30 different data points from your work sessions and produces 129 insights on the way you work. You can check important statistics anytime from the analytics page and, starting after your third week of our program, you will receive a weekly summary containing personal insights on your habits and special "insight challenges" to improve them. Improve with Challenges : Our challenges provide you with both a personalized and a structured system for improving your focus and work habits over time. Join the Community: Learn to focus deeply alongside other ambitious people and high achievers. Achieve Flow State on Command: Columnam is built to train you to enter "flow state," the mental zone where you work better and faster with greater understanding. Rigid Structure = Improvement: rely on a focus optimized system that guides you through success; not motivation, willpower, or "Dopamine Replacement." Not Pomodoro: Columnam is built to fix your broken attention span, not to cater to it. Your Life is not a Game: badges, streaks, and little birds won't help you. Columnam has no gamification Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
