Personality: 16 Types & Big 5 · HarmonyOS

Help & support

Two sourced personality questionnaires for reflecting on everyday patterns.

16 types: the full 32-item OpenJung adaptation of OEJTS 1.2 explores E/I, S/N, F/T and J/P preferences. Raw scales range from 8 to 40, midpoint 24. An exact midpoint is shown as X rather than forcing a type. This is not the official MBTI and is not affiliated with its owners.

Big Five: all 50 IPIP Big-Five Factor Markers with their published scoring keys. Reports show five raw sums from 10 to 50, not population percentiles, accuracy or intelligence scores.

Each questionnaire has separate local progress, reports, answer review and deletion. Answers are not uploaded. Free, without ads, accounts, in-app purchases or analytics SDKs. Multiple interface and content languages.

Sources: public-domain IPIP items; Traditional Chinese by Sih-Ci Jhu, with script conversion for Simplified Chinese. The 16-type questionnaire uses existing OpenJung texts, adapted from OEJTS by Eric Jorgenson / Open Psychometrics. Its questionnaire content and our content adaptation are provided under CC BY-NC-SA 4.0. The Chinese translations and this app have no independent psychometric validation or local norms.

For adult self-exploration, not diagnosis, treatment, hiring or relationship decisions. Sources, scoring, licenses and limitations are available inside the app.
