The Cognitive Execution Operating System for Humans

Where does the story of ReNext begin?

The common scenario：When a task is in chronological order, it may be disrupted by two completely different tasks of projects. Especially when it comes to managing relationships with dozens of clients/family.

A simple conclusion: Productivity is broken.

Reality: Productivity tools haven’t evolved in 20 years. Unbelievable. How dare they? We need to break the industry’s curse.

The truth

Humans don’t think in tasks.

They think in: meaning, memory, direction, and goal/dream.

But modern tools just ignore this.

The efficiency

High efficiency(One of 7 basic design concepts of the iPhone/Steve Jobs): that is, simple, clear and natural. No chaos, no interference, no detour. The memory resources of the human brain are limited, reducing non-intuitive memory, thinking levels, interactive steps, and increasing intuitive associations. — The Art of iPhone Review by Shakenal Dimension

Transfer it to simpler terms. When we talk about efficiency, we talk about accuracy, process, time, and energy. In three layers: thinking, remembering, and executing.

There’s always a long gap between thinking and executing, which is why we need productivity tools to help us remembering.

What's ReNext?

ReNext is a system for thinking, remembering, and executing. Built for the AI era.

From task management → cognitive execution
From task → What's the task and goal/dream? Where did it come from, and where was its path? Where does the ultimate goal/dream go?

The core idea of ReNext & Make the app cool again

The only thing I dare call innovation: the Revolutionary Philosophical Cognitive Framework. It extends the classical philosophical question: Where I come from, who I am, where I am going. The past reality cannot define you; neither can your dreams of the future. Only the fusion of past and future, reality and ideals, truly defines who you are right now. So is to-do. Your brain remembers experiences better than thought. It evokes memory through structure, helping you reconnect with past actions, present identity, and future goals/dreams.

Its expand: Breakthrough project management. Traditional to-do apps fragment thinking. It uses to-do groups as the atomic unit, keeping projects coherent across all pages—no chaos, even with identical task names, even after years. Think in projects, not fragments.

Follow & Lead the time (Just by the way for more efficient): Bottom-up & natural thumb-centered interaction for one-handed user experience. Interaction zones are placed in the most natural thumb-reachable areas, eliminating unnecessary hand switching, mental friction, and interruption. Stay in flow—anytime, anywhere, with one thumb. Every gesture follows your thumb’s natural movement trajectory. Swipe, drag, long-press, and universal back gestures are optimized for comfort, speed, and joy. Productivity should feel intuitive, not exhausting. And Apple is also gradually trying to change to keep up with the times, but it doesn't dare to go all in.

The breakthrough of ReNext

One-handed UX + single-unit cognition = flow state productivity

Theoretical: Reduce memorization time by 40%–70%. Reduce task fragmentation time by 44%. Cognitive switching cost reduction 30% ~ 70%. 3× project completion efficiency.

ReNext vs. Traditional Tools

They are all converging. No innovation, even no change.

Since the internet has thrived, especially the mobile internet, software/apps has become the greatest part of our lives, but there is no one leaving space for software/apps in their products. Even Apple. But I do.

Because they don't believe they can do better, make more money, and are even more afraid of angering their shareholders, so they do not dare to change until others succeed. But I have nothing to lose.

Who needs ReNext?

1B+ global knowledge workers.

For example: managers, office workers, salespeople, teachers and students, government employees, creators, artists, writers, freelancers, and the self-employed.

Why now? It's the era of AI.

I have to admit that it’s the era of AI. AI increases output.

But it also brings risks: noise, distraction, uncertain accuracy, more processes, and hard to save time and energy.

We believe that computers significantly improve efficiency because they drastically reduce the time and energy required for calculations without adding new processes and with nearly 100% accuracy. However, quantum computers that cannot achieve such high accuracy will always struggle to enter the commercial market. Software may crash due to logical errors, but it must not produce errors in its calculations, because calculations are the very foundation of everything; if they fail, everything will be built on a foundation of error.
AI can make mistakes. Even achieving a 70% accuracy rate is challenging for AI, so it’s difficult to rely on it as infrastructure with 100% accuracy. On the contrary, determining whether an AI’s response is accurate requires a higher level of knowledge than the AI itself possesses.
So while AI saves time and effort, it also reduces accuracy and adds an extra step to the process. It’s hard to say that AI has actually helped us improve efficiency.
By the way, AI (especially AGI, which I don't believe will come true if no one will redefine it without a shred of shame or no one will upgrade the AI’s chain of thought into a complete Sacred Chain-of-thought: Philosophy ➡️ Instinct and human needs ➡️ Humanity ➡️ Religion, morality, and law ➡️ Values ➡️ Thinking system ➡️ Theoretical system ➡️ Experience system ➡️ Character ➡️ Emotion.) wants to replace everything. But when working across different fields, efficiency hinges on focus; all-in-one tools/platforms will always distract us from chasing passing the time(entertainment)—it’s human nature—and this is why AI cannot replace specialized categories, as X can't replace vertical-specific forums/media.

Efficiency becomes everything.

Think different

ReNext

The completed to-do, the next to-do, and the to-do following that next to-do (ReNext) form the most fundamental project/unit within ReNext.

Vision

ReNext becomes: The layer between human intention and ultimate goal/dream.

Philosophical Principle

 Tao: Toward Goodness.The goodness: the way to meet instincts and needs in a way that is higher than the relative social or group consensus.

Technology should help humanity create a happier, more natural life, rather than deprive people’s abilities or even trap them within it.

As technology advances, the resulting increase in efficiency frees humanity from the struggle for survival. This newly gained time should be devoted to the pursuit of a meaningful life.

However, driven by human nature and deliberate temptations, the vast majority of ordinary people instead seek extreme emotional thrills to fill the void in their souls. This is the logic behind the decline of human civilization.

Thus, the regression of human civilization in tandem with technological progress has become a pattern. This is not the original sin of technology, but rather an inevitability resulting from the combined influence of human nature and deliberate temptations.

Design philosophy

Love and Nature. Minimalist. Human-Centered.

Nature Is Simplest: Font, color and space replace heavy frames and lines, inviting exploration and discovery.

Balance: Based on "Tao", that is, weakens the impact of defects as much as possible and strengthens the sense of existence of advantages, so that the whole is in the best state of balance.

Humanity: Humans make tools to meet human instincts and needs, not to endure their defects, otherwise they are anti-human.

Optimal Visual Effect Ratio: providing better visual design under the premise of realizing the same product functions.

Global unified: every component and each design element follow the same design concept.

Exquisite (elegant): to pursue the maximum amount of visual information in the minimum visual unit, and the perfect spatial combination of all visual amounts of information.

Extreme: to do our best to pursue the perfection of every detail. Don't believe in the closeness of the feeling, but in the accuracy of numbers.

High efficiency: simple, clear and natural. No chaos, no interference, no detour. The memory resources of the human brain are limited, reducing non-intuitive memory, thinking levels, interactive steps, and increasing intuitive associations.

The design of ReNext logo

The primary colors are hex 777777, hex 2473EE, hex 73E247, and hex AEAEAE. The ReNext Logo background uses hex 73E247 with 12% opacity. Hex 777777 squares represent completed to-dos. Hex AEAEAE horizontal (hidden) and vertical lines on the Hex 777777 squares provide visual emphasis. Hex 2377EE square represents Next to-do, while hex 73E247 squares represent ReNext to-dos.

The story between me and ReNext

With my company was facing bankruptcy and mounting debt, I wanted to take some time off. Despite the immense pressure from those around me, in the last 2023–2024, I have written 3 books. I used Ulysses to complete it on my iPhone. I focused on one thing. My head always contains all the complete frameworks, levels, and details of a book, because I need to immediately locate where I need to change and add. So I need to know what kind of book I want to write, what I want to write next, and what I have written. I really don’t need any tools to help me remember. But I only sold one copy of the book I wrote. But in 2026, I had a bit more luck and sold two copies. Actually, my main goal is to challenge myself to think more systematically and pass on what I’ve thought. Making money is secondary; if it happens, that’s a bonus. But that makes it hard to face my family, because as far as they’re concerned, if you don’t make money or achieve fame, you’re a loser no matter what. After I was existing from that state and moving on in life, life is full of small/big things that distract me, and I find it hard to achieve the same level of focus I had when writing a book, even with productivity tools. I used to use OmniFocus — the most expensive one — but I really use it less. Even people say it’s professional, but I think it's difficult to use, and it’s just another normal to-do reminder with new skin for me. I worked with my former partner — the founder of Lab 11 UK— on the Zones. But it was far away from my thoughts, so I decided to make it myself. Why didn't I do it in 2021? Because I thought learning a coded language for me to focus on operations was hard and meaningless. Fortunately, the AI works well in 2024, and I have written books for 2 years, so don’t let my parents worry. I borrowed money from my parents, brought a second-hand basic MacBook Pro, and a subscription to Apple develop, with the AI help, I'm learning from practice, even though I can’t write code from zero, but I know the basic framework of Swift and know how to change like my original thought. But a year has gone by, and I still haven't made a single penny. I just wanted to make the coolest things that make me satisfying and delightful. To normal users, minimalism feels so comfortable it goes unnoticed; but those who delve deeper will find nothing but surprises and moments of deep emotion. After all, I lean more toward conceptual and research-oriented work, so I lack design experience, and there may be some details that are beyond my abilities.
By the way. I really hate how iPhones keep getting bigger and bigger without regard for the user experience and the peak of product design built by Steve Jobs.
