QA Device Coordinate Map — Template

How to Use This File

This is a template for documenting your app's tap targets. Fill in the coordinates for your specific app by:

  1. Take a screenshot: agent-device screenshot /tmp/debug.png
  2. Open it in an image viewer
  3. Measure the tap target position in pixels
  4. Divide by the device scale factor to get logical points
  5. Record the coordinates below

Device Dimensions

iPhone 16 Pro (default)

  • Logical resolution: 402 × 874 points
  • Pixel resolution: 1206 × 2622 (3x scale)
  • Safe area top: ~59 points (Dynamic Island + status bar)
  • Safe area bottom: ~34 points (home indicator)

iPhone 15 / 16

  • Logical resolution: 393 × 852 points
  • Pixel resolution: 1179 × 2556 (3x scale)

Pixel 8 / 9

  • Logical resolution: 411 × 915 points
  • Pixel resolution: 1080 × 2400 (2.625x scale)

iPad Pro 11"

  • Logical resolution: 834 × 1194 points

Bottom Tab Bar

Most apps have a bottom tab bar. Measure the Y position and X position of each tab.

Tab Name x y Notes
1 (your tab) ___ ___
2 (your tab) ___ ___
3 (your tab) ___ ___
4 (your tab) ___ ___
5 (your tab) ___ ___

Tip: Tab bar Y is usually around 850-860 on iPhone Pro models.

Common UI Elements

Element x y Notes
Back button (top-left) ___ ___ Usually ~30, 60
Settings/Menu (top-right) ___ ___ Usually ~380, 60
Screen center ___ ___ ~200, 437 on iPhone Pro

Screen-Specific Elements

Screen: (your screen name)

Element x y Notes
(element) ___ ___
(element) ___ ___

Screen: (another screen)

Element x y Notes
(element) ___ ___

Tips for Finding Coordinates

Method 1: Screenshot + Image Viewer

agent-device screenshot /tmp/debug.png
open /tmp/debug.png  # Opens in Preview on macOS

Use Preview's inspector to read pixel coordinates, then divide by scale factor.

Method 2: Accessibility Snapshot

agent-device snapshot -i

Elements with tap targets show bounding boxes. Use the center of the box.

Method 3: agent-device highlight

agent-device snapshot -i       # Get refs like @e1, @e2
agent-device highlight @e1     # Highlights the element on screen

Method 4: Trial and Error

agent-device click 200 400     # Try a tap
agent-device screenshot /tmp/after-tap.png  # Check result

Using Coordinates in Tests

Set coordinate overrides in qa.config.sh or qa.config.local.sh:

# Tab bar
export TAB_BAR_Y=855
export TAB_1_X=60
export TAB_2_X=170
export TAB_3_X=290
export TAB_4_X=400
export TAB_5_X=520

# Custom elements
export BACK_BUTTON_X=30
export BACK_BUTTON_Y=60

Then use them in test scripts:

source qa.config.sh
tap $TAB_1_X $TAB_BAR_Y    # Tap first tab
tap $BACK_BUTTON_X $BACK_BUTTON_Y  # Tap back
