Koss Applications

Applications that turn
complexity into clarity.

We build apps that take messy, overwhelming information and make it useful. From wearable health data to AI prompt engineering, our work is about giving you the context to act with confidence.

Built in 2026 Two apps live Solo Developer

Two apps, one philosophy.

Make the complicated easy to use, and easy to understand.

How we build.

01

Context, not noise

A metric without meaning is noise. We design every feature to explain what it means and why it matters to you.

02

Useful, not exhaustive

We'd rather show you the three things that change your day than the thirty that don't. Clarity beats coverage.

03

Designed to act on

Whether it's health data, or AI prompting, we design to give you the ability to act on that information.

Artifex Health

Health insights
that help you act.

Artifex Health turns wearable and body data into clear, actionable insights so you can understand how you feel, train, and recover.

Our mission.

One health app that brings your wearable, body, lab, and nutrition data together — then ties it all into insight you can actually use.

With backgrounds in professional gaming and a deep love for the health and wellness space, we design with intention. Seeing your own metrics is great — but we want you to do more than look. We want you to act. Artifex Health makes you aware of your metrics, gives you context behind them, and offers a personally curated path to improving them. Earn achievements, track your trends, and chat with an AI coach that pushes you toward better habits, every day.

Inside the app.

Artifex Health transforms raw wearable and phone data into meaningful feedback. Instead of disconnected metrics, it ties them together to help you understand what changed, why it matters, and what to do next.

  • Sleep stage & quality
  • Daily readiness
  • Heart rate trends
  • Activity tracking
  • Calorie burn
  • Nutrition logging
  • AI coaching
  • Personal goals

The right model.
The right prompt.

Mycelio optimizes every prompt behind the scenes and routes it to the best AI model for the job — so you stop fighting with phrasing and start getting richer, more accurate answers with less effort.

How Mycelio works.

Three steps happen the moment you hit send.

1

You write a prompt

Type your idea however it comes out — rough, short, or messy. No prompt-engineering skills required.

2

We optimize it

Mycelio rewrites your prompt into a clear, expert-level instruction designed to pull the best possible answer.

3

We route to the best model

It picks the ideal model for your task — or you choose — across Anthropic, OpenAI, Google, DeepSeek and more.

From rough idea to expert prompt.

Most people never get the most out of AI because writing a great prompt is hard. Mycelio does it for you — expanding your request with the context, structure, and detail that top results require.

  • Turns one-line asks into rich, structured prompts
  • Adds the context models need to respond accurately
  • See exactly what was optimized before it runs

One prompt. Every model.

Different models are great at different things. Mycelio routes each prompt to the best fit automatically — or run the same prompt across several models and compare answers side by side.

  • Auto-routing picks the best model for each task
  • Compare responses across models in one chat
  • Switch models mid-conversation, anytime
