Quartenson Tools - Free cognitive practice tools for short focus sessions

by•
Quartenson Tools is a set of free browser-based tools for short focus and visual-attention practice. Try Schulte tables, visual search, visual memory, peripheral awareness, and reaction time exercises. Each tool supports quick, repeatable sessions with clear metrics and same-setup comparisons. For deeper Schulte practice, the Android companion adds session history, pace analysis, heatmaps, trends, goals, and achievements. Built for practice and self-comparison - not diagnosis.

Hi Product Hunt - I’m Mike, the solo maker behind Quartenson.

I started Quartenson because many cognitive tools either overclaim or reduce performance to a single score. I wanted something more practical: short exercises, clear metrics, and comparisons that keep the setup and task context visible.

The free browser toolkit currently includes:

– Schulte Table Trainer
– Visual Search Test
– Visual Memory Test
– Peripheral Awareness exercise
– Reaction Time Test

I’ve also built Schulte Vision Trainer for Android for people who want deeper Schulte practice and progress tracking, including session history, pace review, heatmaps, weekly and monthly trends, goals, and achievements.

The principle behind Quartenson is simple: useful context over labels. The tools are intended for practice, observation, and personal comparison - not medical or diagnostic assessment.

I’d especially appreciate feedback on:

  1. Which tool did you try first, and why?

  2. Were the results and metrics easy to understand?

  3. Would you prefer more browser tools or deeper mobile companions?

Thanks for checking it out. I’ll be here throughout the launch to answer questions and hear what you think.

love that the metrics and setup stay identical across runs so you can actually compare sessions instead of just guessing if you improved. the same-setup comparison choice shows real respect for the practice side of things.

Thanks! That was exactly the goal - making progress comparisons meaningful without reducing everything to a single score.

The same-setup comparison framing for Schulte tables is a smart UX choice, it keeps the focus on progress rather than chasing arbitrary scores across different layouts.

The Schulte table loads fast and the color scheme is easy on the eyes during longer sessions. Like that progress is tracked simply without overpromising any cognitive claims.
