About

independent developers who do not want to be oxen and horses. However, I have been learning how to make products since January this year, so I feel ashamed to call myself an independent developer. But I want to use this to motivate myself.

FocusAge - How old is your focus? Find out in 3 minutes.

FocusAge is a free 3-minute web test that measures your focus, attention and working memory across 5 dimensions — then shows you a "Focus Performance Age" compared against age-group benchmarks. Run 3 short challenges (a Stroop color task, a Schulte attention grid and a memory round), get a radar breakdown of your strengths and weak spots, and walk away with a personalized 7-day plan to sharpen the dimensions you scored lowest on. No signup. No email. Everything runs in your browser.
