How it works

STEP 01

Take the Spark

30 questions. 5 minutes. Based on 60 years of Big Five personality science. You'll never need to retake it — the app calibrates from here.

STEP 02

Meet your archetype

Your personality profile — named and explained. Not a label. A compass. Scores across 5 traits, described as tendencies, never diagnoses.

STEP 03

Your plan grows with you

Daily Plan habits and weekly Practice exercises matched to your traits. The more you use it, the smarter it gets. Your coaching profile deepens over time.

Plan + Practice

Plan

Your daily habits, built for you

3–5 daily habits matched to your archetype and trait profile. Each one tied to a specific growth area — Warmth, Trust, Modesty — not a generic to-do list.

Example for The Architect: "Pass the praise around" — builds Warmth. Matched because your Agreeableness score shows a growth edge here.

Practice

Weekly exercises for real growth

Short reading, writing, reflection, and listening sessions matched to your growth edges. 5–10 minutes. Science-backed. Never the same for everyone.

Example for The Architect: "Look at your plate before yes" — a reading on over-commitment patterns common in high-Conscientiousness profiles.

Science + trust

60 years of science

IPIP Big Five — the most validated personality model in psychology.

Your words stay yours

Reflections and notes are encrypted. Even we can't read them.

Insight, not prescription

Tendencies, not diagnoses. You choose what to act on.

Grows with you

Profile calibrates deeper over time. Never starts over.

FAQs

What is a Spark?

A free 5-minute assessment of about 30 IPIP-style questions that maps your Big Five traits and assigns an archetype. It is your starting point, not the whole product.

How is this different from 16Personalities?

16Personalities uses type labels inspired by Myers-Briggs. NEO-120 uses continuous Big Five scores from IPIP science, then matches Plan and Practice to your facets over time.

What do I actually do every day?

Complete a few Plan habits matched to your growth edges, plus short Practice sessions (read, write, listen, reflect) that renew with your coaching profile.

What does the calibration percentage mean?

Calibration shows how complete your profile sync is as you deepen measurement in short bursts. It does not rewrite your Spark into a new personality overnight.
