TL;DR
You don’t need steady hands: in iPhone Photos Markup, hold after drawing and your circle/arrow/line snaps into a clean shape.

Checked  When you circle something on a screenshot to show someone, it usually looks like a wobbly mess. But iOS has a hidden trick: **hold your finger down after drawing** and it snaps into a perfect shape. ## How to do it 1. Open **Photos** > pick an image > tap **Edit** > tap **Markup** (pen icon) 2. Draw a shape — circle, line, arrow, rectangle, star, or even a speech bubble 3. **Don't lift your finger** at the end — hold for about half a second 4. Watch it snap into a clean, geometric shape 5. Tap to accept, then drag the handles to resize or reposition ## Shapes that iOS recognizes | You draw... | iOS makes... | |---|---| | Rough circle | Perfect circle or oval | | Wobbly line | Straight line | | Sketchy arrow | Clean arrow | | Rectangle-ish shape | Perfect rectangle | | Triangle | Equilateral or right triangle | | Star | Five-pointed star | | Heart | Clean heart shape | | Speech bubble (cloud) | Thought/speech bubble | ## Where Markup works It's not just Photos. You can use Markup in: - **Screenshots** — tap the thumbnail that appears after taking one - **Files app** — open a PDF and tap the pen icon - **Mail** — tap an attachment in a draft, then Markup - **Notes** — tap the pen icon to draw - **Messages** — long-press a photo, then Markup ## Why this is genuinely useful Clean annotations make your communication clearer. Instead of a messy red scribble around a button, you get a precise circle that says "this, right here." It's the difference between looking amateur and looking professional — in bug reports, instructions, or design feedback.
