iPhone Giveaway of the Day - Oilbook - Fluid Painting

I've always wanted to develop an oil painting app. After trying existing solutions on the market, I found that they only mimic the texture of oil paintings, which I believe is not perfect. Pigments are essentially a liquid, so my goal is to authentically recreate the dynamic process of paint flow and diffusion based on fluid mechanics and other physical principles. This vision led to Oilbook — a truly unique software.

The default brush can adjust the number of bristles and the size of the brush. The fluidity of the pigments can also be adjusted. Other brushes can adjust texture, size, point distance, hardness, direction, opacity and other parameters.
Reducing 'Bristle Count' can sometimes improve the effect. For some brushes, it is better to adjust the hardness. For example, please try to adjust the hardness of some brushes to 0.

Supports multiple undo/redo.
Supports switching between portrait and landscape modes.
A large number of oil painting texture color presets with adjustable intensity can be applied to your work.
You can choose colors, use the eraser, clear the canvas, switch full-screen mode. The current project progress can be saved, and the archive can also be deleted. You can save your work to photo album or share it.
In Apple Pencil mode, the stroke thickness will change in real time with the pressure.
There is a user guide in the settings page.

In the pro version you will:
- Get all brushes and color presets, and they are constantly being updated.
- Remove watermark.
