About
A small app for observing yourself, like standing on a shore at dawn.
Don't rush, don't answer, just wait — a gentle dialogue practice
that quietly reflects the patterns in your choices.
[ FREE FEATURES ]
- Step into 8 scenarios with 6-8 choice options each
- Situations are adapted to 10 occupations:
Office worker / Student / Self-employed / Homemaker / Teacher /
Researcher / Software engineer / Hardware engineer / Sales /
Senior or second-career
- Visualize your tendencies on an 8-axis radar chart:
Situation Analysis / Problem Solving / Project Management /
Strategic View / Scholarly View / Collaboration [Same Page] /
Decision Speed / Long-term View
- 16-type personality observation with primary and secondary tendencies
Each letter (I/E/N/S/T/F/J/P + Identity) explained in gentle prose
- "Dissonance button" to record the very feeling of pausing
- Suggestions of suitable roles and complementary axes by personality type
- "Your Bookshelf" - 108 curated titles, matched to your personality
and tendencies (Hayao Kawai, Sandel, Kahneman, Harari, and more)
- Four font sizes, supports Japanese / English / Simplified Chinese
All processing happens on-device. No personal information is collected.

[ ABOUT THE NAME KAILUA ]
Kailua is Hawaiian for "two seas" (kai = sea, lua = two).
A place where two waves meet — yourself, and AI.
[ THE NORTH STAR OF THIS DESIGN ]
This app chooses to be a supporting actor in your relationships.
- It does not maximize time spent
- It does not call you back with notifications
- The AI asks back gently rather than answering
- "Curating the dialogue space" is the app's real work
