The Old Guy Judo Journal application (“the App”) exists to help grapplers become more intentional, reflective, and effective in their training.

Most of us spend hours on the mat each week learning techniques, drilling, sparring, and solving problems. Yet much of that learning is forgotten within days. The goal of the App is to help practitioners capture those experiences, recognize patterns over time, and turn training sessions into lasting knowledge.

The App started as a tool I built for myself. As an older beginner, I wanted a way to be more intentional about my training, reflect on what I was learning, and identify opportunities to improve. Over time, I realized that many other grapplers face the same challenge of turning training experiences into lasting lessons, so I decided to make the tool available to others.

At its core is a simple belief: thoughtful reflection helps practitioners learn more from the training they're already doing.

What the App Is

The Old Guy Judo Journal App is a training reflection tool.

It helps you:

• Log and review training sessions

• Track techniques you've learned and practiced

• Identify recurring themes and trends in your training

• Build a personal knowledge base of your grappling journey

• Use AI-assisted analysis to surface insights that might otherwise be missed

The goal is not to replace coaching, instruction, or mat time. The goal is to help you get more value from the training you're already doing.

What the App Isn't

The App is not intended to be:

• A social network

• A belt promotion tracker

• A replacement for instructors or coaches

• A competition management platform

• A commercial software product with a full-time development team

It is a passion project built by a fellow practitioner who enjoys both judo and technology, and who believes that thoughtful reflection can accelerate learning.

Who It's For

The app is for grapplers who enjoy learning.

Whether you're a brand-new white belt, a lifelong black belt, a recreational practitioner, or a competitor, the journal is designed for people who want to understand their own training better and preserve the lessons learned along the way.

A Note on Feedback

Feedback, bug reports, and ideas are always welcome.

However, every feature request is evaluated against the mission of helping practitioners reflect more effectively on their training. Not every suggestion will be implemented, and simplicity is often preferred over adding more features.

The goal is not to build everything.

The goal is to build something useful.
