Aging Curve Test

In Korean gaming slang, "aging curve" is what you blame when your hands stop keeping up. Aging Curve Test turns that joke into something you can measure. Twelve mini-tests cover six abilities: reaction (simple and choice reaction time), aim (flick and tracking), timing (stop-the-hand and keep-the-beat), judgement (Stroop and go/no-go), memory (sequence memory and the chimp test) and hand speed (CPS and APM).

A quick run takes about three minutes and a full run about seven. At the end you get a score per ability, a radar chart, a gamer type and a "physical age", which you can save as an image or send to a friend as a challenge link. Every test also has its own page for practice.

The scoring is published in full on the site, including the anchors for each test and the formula for the age. The site notes that reaction slowing from age 24 comes from a 2014 PLOS ONE study of 3,305 StarCraft 2 players. It is a game, not a medical test. Free, no account, nothing to install.
