A museum-inspired app for iPhone & Android

Restore masterpieces.
Return to a living gallery.

Cadrelle is a private museum you carry with you. Restore famous paintings piece by piece, then step into a gallery that changes over time — with curator’s notes, daily highlights, and monthly exhibitions.

Not a puzzle app with paintings in it.
A living museum that happens to begin with a puzzle.

i · Restore

The work returns
in pieces.

Fragments gather as you move them. A painting reveals itself slowly, then all at once. No coins. No confetti. No noise — just the painting coming back to its frame.

ii · Discover

A curator’s note,
not a trivia trap.

When the frame is whole, the work opens. A short, intelligent note explains the painting’s technique, its world, and what to notice the second time you look. Go deeper if you want. Move on if you don’t.

iii · Progress

Move through
the canon.

Seven collections, arranged chronologically. You are not just finishing paintings — you are moving through centuries, one restored work at a time. Selected rather than scraped.

  • Renaissance
  • Baroque
  • Dutch Golden Age
  • Rococo
  • Romanticism
  • Impressionism
  • Post-Impressionism
Cadrelle app: permanent-collection rooms view showing Post-Impressionism, Baroque, and Rococo with editorial subtitles.

iv · Return

A museum that
keeps changing.

Cadrelle is run like a small cultural institution, not a static library. Each day, Today’s Highlight surfaces one work. Each month, a new seasonal exhibition — like When the World Blooms — opens around a single idea. You never return to quite the same museum twice.

Membership to a
living museum.

Cadrelle is offered as a membership in the museum sense: one price opens the full permanent collection, plus every exhibition, daily highlight, and guided programme that follows. You are not buying a fixed bundle of puzzles. You are entering an evolving cultural space.

No tiers. No premium paintings hidden behind another paywall. No ads. A short trial lets you restore your first works before deciding. Cancel anytime from your phone’s settings.

The Permanent Collection

  • Real masterpieces from major museums
  • Curator’s notes on every work
  • Adjustable difficulty, from a few minutes to an evening
