Thought-filled Words by Sonder

365 untranslatable words for the feelings we all have and rarely have language for — each one a painting that moves when you touch it.

The first words are yours the moment you open the app. One purchase unlocks the whole collection, for life. No ads, no account, no subscription.

Certain feelings seem too specific to be captured by one word. Until you read a word whose definition describes them so perfectly that you realize you're not the only person to have felt them.

It looks like a museum: every word hangs as a painting that wakes when you touch it. It feels like a book: you wander page by page, at your own pace, with nothing asking anything of you.

Every word becomes a scene of its own: a few seconds of light and motion that fill the screen. You can sit inside it, drag back through it frame by frame, and hold it still whenever you want. Erik Satie's Gymnopédies play softly the whole way through.

No two scenes look alike, and yet you never jump. Each painting finds its way into the next through a transition made only for that pair — unpredictable every time, obvious the moment you see it.

Behind each word is far more than a definition. There's a moment, written to let you feel it from the inside. All of it rests on paper you can make your own: the texture, the typeface, the torn edge, the colors you mark your favorites in. A book that happens to live on your screen.

It even begins the way a book does, with an overture, a poem, a slow breath, before opening into chapters you move through at your own pace.
