精神年齢/診断

精神年齢/診断 is a lightweight (about 3MB) Chrome extension that allows users to measure their "mental age" through a quick and engaging quiz. By answering 20 intuitive questions, users can discover whether their mind aligns with that of a child, teenager, adult, or beyond. The app is designed for fast diagnosis, suitable for parties, social gatherings, or simply to kill time during commutes.

The user-friendly interface lets you enter your real age and then select from four options per question. Results are fun and shareable, with a feature to post directly on Twitter. While the diagnosis provides entertaining insights, it is not comprehensive but offers a playful exploration of the gap between body and mind. Compatible with Android 4.4 or higher, this free extension keeps users updated with future releases via push notifications.
