Choose a built-in artwork, select a numbered gem, then tap an empty matching number. Start on an empty matching place and hold and glide to fill more. Starting a stroke on blank canvas moves the canvas. Use two fingers to move, zoom and rotate.

Open Free canvas from the home screen. Choose a gem, color, size and direction, then tap to place it. Select an existing gem to move, rotate or remove it. The menu offers Undo, Redo and Expand canvas. Use two fingers to zoom and move. Free canvas currently uses individual taps; continuous glide-to-fill applies to numbered templates.

Returning saves the canvas on this device so you can continue later. Choose Done and confirm to add it to your completed collection; empty spaces and grid lines disappear. You can change the background. To rearrange gems in a finished creation, make a copy and preserve the original.

Double-tap a gem in the bottom palette to find an unfinished area for that gem. This moves the view; it does not fill the artwork for you.

The app follows its preferred language and supports Simplified Chinese, English and French. All three languages use the same artworks and local saves. Open the language option in the app settings, then go to iOS Settings to choose a language. Switching languages does not create another set of works.

Open Collection to continue a work or enjoy a completed creation. Creating another copy preserves the earlier creation. Numbered artworks and free creations are stored on this device.

For numbered artwork, choose Save PNG to Files or Share. For a free creation, choose Save image in the menu, then select a destination in the system sheet. Open the saved PNG to check it. A PNG is an image, not an editable backup. Set device wallpaper separately in system settings.

App-managed cloud recovery is not available. Progress stays on this device and may be lost after uninstalling, changing devices or device failure. Do not uninstall as a troubleshooting step.

The first release is free, without ads, in-app purchases or subscriptions. There are no purchases to restore in this version. Built-in artworks can be created offline after installation.

The first launch is planned for the U.S. App Store. This website will show a download link once the app is available. Mainland China availability is pending. A website in three languages does not mean downloads are open in every country or region.
