User Manual

Just four steps: draw, confirm, save, share.

1. Drawing

The app opens on the Draw tab. Pick a paper shape (square, portrait, or landscape) to open the canvas. The toolbar at the top lets you choose pen color, width, and opacity, and you can draw freely with a finger or Apple Pencil. Pinch to zoom in up to 8x for fine detail. The eraser is also in the toolbar.

While you draw, your work is autosaved only on your device, as a draft. Nothing is sent over the network at this point.

2. Undo and Redo

Use these gestures anywhere on the canvas:

• Two-finger tap — undo the last stroke
• Three-finger tap — redo an undone stroke

There's no button to find — you can undo or redo from anywhere on the canvas without stopping what you're drawing.

3. Paper settings

Paper color, line color, and background pattern (blank, horizontal ruled, vertical ruled, grid, dot grid, or manuscript) can be changed any time from the paper icon in the canvas toolbar, not just when you first choose the paper.

4. Confirming and saving to the server

When you're done, tap the checkmark at the top right. A movie plays back exactly how you drew it, so you can confirm it looks right. If you're happy with it, tap "Save to Server." Until you do, the work stays as a local draft no matter how many times you close and reopen the app.

"Save to Server" requires signing in with Sign in with Apple. Once saved, you get a share link you can copy or send with the Share sheet.

5. History

The History tab shows on-device-only drafts (a blue "Draft" badge) alongside posts already saved to the server, together in one grid. Saved posts also appear on other devices once you're signed in there.

Opening a post someone else shared gives you a "Duplicate to Edit" option, which copies it into your own drafts to continue from (the original itself is never changed).

6. Sharing

The share link you get after saving opens in any web browser, with no app required. Paste it anywhere you already post — LINE, X, wherever — and anyone can watch the replay.

7. Reporting

The web page a shared link opens has a "Report this post" link. Anyone who sees something inappropriate can report it from there, no sign-in required. Reports go straight to us, and we review and act on them directly.

8. About ads

There's a single ad slot, clearly labeled "Ad," on the History tab only — no other screen (drawing, confirming, sharing) ever shows one. Ads are always non-personalized, and a failed ad load never affects any other feature.
