Interaction Latency

Time from user tap to action successfully completed.

When to Use

"Add to cart" button tapped → cart updated
"Submit" button tapped → form processed
"Like" button tapped → state changed
Any tap that triggers async work

Measurement Pattern

TAP → START_SPAN → [async work] → END_SPAN

Capture tap timestamp
Start span with operation name
End span when action confirms success
Include success/failure outcome

Key Thresholds

Rating	Duration
Good	<300ms
Acceptable	<1s
Poor	>1s

Implementation

See

references/ui-performance.md

(Entry Point Latency section) for platform-specific code.

Common Mistakes

Ending span on API call start (not completion)
Not tracking failure cases
Missing the tap timestamp (starting late)
