Purchase fixes. - If you bought Lifetime, Settings no longer shows a Manage subscription button that had nothing to manage. - Settings and the Pro screen now link to the legal notice required in Japan.

Made for iPhone Duo and wider screens. - On an open iPhone Duo, the Learn list and lessons sit on either side of the fold. Lessons scroll the explanation and preview separately from the code and hints. - The preview on the Create screen now reaches the screen edges, and recent shaders and presets show larger on wide screens.

A friendlier Export screen. - Each file's how-to now lives behind a How to use button, so the code gets more room. - Copy the file you're viewing from the top-right of the code, or every file from the button below. - Settings now shows when the on-device model is still downloading and when it's ready.

New: the Learn tab. Four hands-on lessons teach Metal shaders by changing one expression at a time in a real shader, with your result checked against the target as you go. - Coordinates and color, and Circles and rings are free. Soft light, and Noise and patterns come with Pro. - Sliders, multiple choice and tap-to-arrange pieces, so most steps need no typing. - Touch a canvas to read its values, see where your picture differs from the target, and open the finished shader in the editor. Also: Settings now opens from the gear button, primary buttons are easier to read, and the English text uses US spelling.

Graphica Playground now speaks Japanese. On-device generation is also more reliable: broken expressions are caught earlier and redrawn.
