Interactive lessons, 3D form, art references and image analysis. Bring observation into your practice.

iPhone & iPad. Not on the App Store yet. In private beta.

From seeing, to understanding, to creating.

See form

Turn a model, study an artwork, change the light. Build ways of seeing.

Understand form

Learn by doing in interactive lessons, then read colour and value through image analysis.

Create form

Save artworks and swatches, arrange a still life and take that understanding into your practice.

01 / LEARN

Try the principle.
See what changes.

Fundamentals, artist lives and art history share a home in Learn. Open a record and start with a concrete question, then look, interact and understand.

  • Interactive lessons. Explore light and shadow, light direction, observation and proportion. Turn the model, move the light and receive feedback.
  • Artist lives and art history. Follow lives and works along timelines, with world, Chinese and Japanese art history and art by country.

Lessons and content are growing. The app distinguishes available entries from those in preparation.

02 / REFERENCES

Build a collection
you can learn from.

Browse eight subjects: portraits, people and daily life, religion and mythology, landscapes, sea and water, still life and flowers, animals, and abstract art and patterns. Art references and 3D models each have their place.

  • Look closer. Read the artist, date, source and licence, then examine the colour composition.
  • Keep a reference. Save favourites, zoom in and use the squint view to reduce detail and see the broad relationships.
  • Your own references. Import from Photos, Files or the clipboard and keep a floating reference beside the model. View saved works and swatches in your collection.

Image use follows the source and licence listed for each work.

03 / IMAGE ANALYSIS

Read the colours
inside an image.

Choose your own photo, or try an artwork from the reference library. Compare the original with its colour masses and see how colour, value and temperature are distributed.

  • Break it down. Inspect colour proportions, names, HEX values, light and dark, warm and cool, and colour relationships.
  • Use what you find. Pick colours from the image, save swatches and find artworks with similar palettes for reference.

Image analysis runs on your device. Your selected photo is not uploaded.

How light builds volume
matters more than memorising a chart.

Move the light and the shading follows. Compress it to light and dark, then see how the shapes sit on the form.

Which step does each surface fall on?

Plane values from 1 to 9, numbered right on the surface.

Screen recording from the app

Complex forms
start simple.

The head in four steps: from blocks to a complete form. You can always step back.

Perspective is not diagrams to memorise.
It is a relationship in space.

Sphere, cone, cylinder: turn on perspective mode and the guides really sit in space. Move the camera and see.

Eyes, nose, ear and mouth are stepped too.

Screen recording from the app

What matters is
not always the features.

Eleven landmarks on the head stay attached to the model and follow it as you turn. Point, leader line, name, region. Bilingual, in a short and a full version.

Once you understand it,
hide the answer.

From looking, to recognising, to remembering.

The real self-test screen: four choices, and the right answer is never highlighted while you test.

Beyond the head, more forms.

Anime, hands and hair turn, come apart and pose the same way.

Anime has form too.

A flat picture comes from a three-dimensional idea.

Some structures you have to
bend to understand.

A rigged hand: every finger joint bends and extends, or jump to a preset pose.

Understand the head first.
Then the hair.

Same head, different hair. The head stays. The outline changes.

A reference does not have to be found.
You can build it.

Set up your own still-life table on your phone: add objects, move, rotate and scale them, drop them to the ground, light them, compose.

See a problem,
mark it.

Annotate on the image, then export a clean reference: transparent background, 2K or 4K, or a greyscale version for value practice.

Who it is for.

Art students and exam candidates

A structure you cannot read: turn it, switch off the light, test yourself again.

Art teachers

The same model, the same light, the same angle. Explain a structure once, for everyone.

Studios

Use the library as a teaching aid always at hand: heads, features, hands, plaster, still life.

FAQ

Can I download it now?

Not yet. It is not on the App Store and is in a small private trial. The trial application channel is being prepared. You can explore the user guide now.

Which devices?

iPhone and iPad with iOS 18 / iPadOS 18 or later. On older devices, use normal shading or fewer still-life objects.

What works offline?

Form and Studio run locally. Sign-in, learning progress sync, content updates and high-resolution originals need a connection. Available entries depend on the current version.

Why do annotations disappear after changing view?

Annotations are 2D marks tied to the current view. They hide when the view changes to avoid misalignment. Set the angle, then annotate and export.

Do palette values use the same scale as model labels?

No. Model labels run from 1 (lightest) to 9 (darkest). Palette lightness runs from 0 (black) to 100 (white).

Is there an English version?

The app offers Chinese, English and Japanese interfaces.

Where do the models come from?

120 models so far. The author, source and licence of each are listed in the app under Settings → About → Third-Party Assets, and credited authors are named in the footer.
