About
The moment you open it, an infinite universe.
SOPHIA turns a passing thought into a "star" and lets you connect stars into constellations — a whole new way to organize ideas.
It isn't a note list, and it isn't a mind map with boxes to fill. Make a star with your fingertip, trace to connect. That's all it takes for scattered thoughts to take shape.
No manual needed. Just touch, and discover.
WHAT YOU CAN DO
・Double-tap to make a star right there. Name it later, at your own pace
・Trace from star to star to connect them with a line of light
・Long-press a star to lift it and move it anywhere
・Group stars by color and see everything at a glance
・Write detailed notes in each star
・"Summary" turns your connected stars into text, in order — a first draft for plans and scripts
・"Snap the sky" turns your constellation into a single image you can share
・A wide universe of four faces side by side. Pinch to see it all
・Keep up to 5 projects and switch between them (full version)
・Export as text or as a project file
・Reorder the star list by long-press — use it as a calm to-do list too
MADE FOR
・People whose ideas tend to scatter
・Anyone planning projects, scripts, articles or videos
・Anyone who wants to sort out meeting notes later
・Anyone who wants to tidy their mind in a light, enjoyable way
ON YOUR PC TOO
There's a Windows version (free trial). Open what you exported from your phone on a large screen and organize it there, with sticky notes and images.
※ Buying on your phone unlocks the full PC version too.
NO ACCOUNT. ONLY ON YOUR DEVICE.
No sign-in. Your stars and words are stored only on your device.
TRIAL AND FULL VERSION
The trial lets you make up to 10 stars and 1 project. If you like it, a one-time purchase gives you stars without limit and up to 5 projects. No subscription. The universe you grew in the trial stays just as it is.
