The Inspiration: A Different Way to Walk

I’ve been using walking as part of my efforts to improve my fitness and overall health.

Like many people, I started by using an existing fitness application to track my steps and monitor my activity. While that was useful, I became interested in the Japanese Walking Method, also known as interval walking training.

The approach alternates periods of faster walking with slower, more comfortable walking.

What interested me was the structure. Rather than simply tracking how far I walked or how many steps I completed, I could follow a routine that deliberately varied the intensity of my exercise.

It seemed like a practical approach to incorporate into my existing fitness activities.

But I wanted more control over the experience.

I wanted to decide how long to warm up, how long to walk quickly, when to slow down, and how long to cool down, without constantly checking a stopwatch or my phone.

That became the inspiration for Niko Fit: Japanese Walking Method.

The Problem: Step Tracking Wasn’t Enough

Most conventional walking applications focus on recording activity.

They measure steps, distance, exercise duration, and estimated calories burned.

Those features are useful, but they don’t necessarily provide the guidance needed to follow a structured interval walking routine.

I wanted an application that could do more than record a walk.

It needed to guide the activity itself.

The experience had to be simple enough to use while walking, with minimal interaction required once a session started.

The Solution: Niko Fit

I developed Niko Fit as a walking application built around structured fast-and-slow walking intervals.

The application offers three program options:

Easy Walking Routine

A predefined 40-minute program designed to provide a more approachable introduction to interval walking.

Standard Walking Routine

A predefined 40-minute program offering a structured fast-and-slow walking session.

Custom Walking Routine

For users who prefer greater control, Niko Fit allows them to create their own interval walking program.

Users can configure:

  • Warm-up duration

  • Fast-walking interval duration

  • Slow-walking interval duration

  • Cool-down duration

This provides flexibility for different preferences, capabilities, and fitness goals.

Designing for the Walking Experience

One of my design priorities was minimizing the need to interact with the phone during a walking session.

When following intervals, users need to know when to increase or decrease their walking pace.

Niko Fit addresses this through voice guidance and notifications that signal when to transition between fast and slow walking.

This allows users to concentrate on their walking rather than repeatedly checking their screens.

The application also provides basic activity information, including estimated calories burned based on personal information such as age, height, and weight.

Keeping the Technology Practical

An important design decision was keeping the initial application focused.

Niko Fit does not currently require integration with a smartwatch, fitness tracker, or other wearable device.

Instead, the application provides a straightforward experience centered on configurable walking intervals, guidance, and basic activity tracking.

This reduces the complexity of the application and allows users to follow their walking routines directly from their phones.

Wearable integration remains a potential area for future development, but it was not necessary to deliver the core experience I wanted.

From Personal Need to Product Development

Niko Fit began with a problem I experienced personally.

I had a fitness goal, discovered an exercise approach that interested me, and wanted a more convenient way to incorporate that approach into my activities.

Rather than accepting the limitations of my existing tools, I decided to build something that better suited my needs.

Developing Niko Fit involved translating a relatively simple idea into a functional application with configurable programs, user preferences, interval timing, notifications, and activity estimates.

The emphasis was on creating a focused experience rather than adding features simply because they were technically possible.

What This Project Demonstrates

This project reflects several capabilities that I bring to product development and operational improvement.

Problem Identification: Recognizing the difference between what existing tools provide and what users actually need.

Product Thinking: Translating a personal use case into clear application requirements and functionality.

User Experience Design: Prioritizing simplicity, configurability, and hands-free guidance during physical activity.

Practical Technology Development: Building an application around a defined purpose while managing scope and technical complexity.

Continuous Improvement: Identifying opportunities for future enhancements without losing focus on the product’s core functionality.

What I Learned

Niko Fit reinforced my belief that useful technology doesn’t always need to solve a complicated problem.

Sometimes the opportunity is to take an existing activity and make it easier, more structured, or more enjoyable.

The challenge is understanding how people will actually use the product.

For a walking application, that means considering what happens when someone is outdoors, moving, and unable or unwilling to interact with their phone constantly.

The result is an application designed around the activity, rather than expecting the activity to revolve around the application.

For me, Niko Fit represents the connection between personal curiosity, practical problem-solving, and application development.

The goal wasn’t to build another step counter. It was to build a walking companion that helped me follow a structured routine on my own terms.
