Phase 01: Input UX Verification Report

Phase Goal: Users can log weight and reps quickly on mobile without fighting the inputs

Goal Achievement

Observable Truths

# Truth Status Evidence
1 Weight field displays "kg" unit suffix visibly ✓ VERIFIED /src/components/WeightInput.jsx passes suffix="kg" to StepperInput; StepperInput renders suffix in .input-suffix span (line 73); CSS styling at lines 1893-1899
2 Tapping +/- increments weight by 2.5kg and reps by 1 ✓ VERIFIED WeightInput passes step={2.5} (line 8); RepsInput passes step={1} (line 8); StepperInput handleIncrement/handleDecrement use step param correctly (lines 36-42)
3 Typing negative values is prevented; stepping below 0 is blocked ✓ VERIFIED handleInputChange enforces min constraint (lines 21-24); handleDecrement uses Math.max(min, numValue - step) (line 32); both components set min={0}
4 All inputs and buttons are at least 44px tall for thumb usability ✓ VERIFIED .stepper-btn is 44×44px (lines 1821-1824); .stepper-container is 48px tall (line 1817); all action buttons have min-height: 44px; mobile optimized to 48×48px (lines 1902-1912)
5 Input font size is at least 16px to prevent iOS auto-zoom ✓ VERIFIED Global rule at lines 1780-1788 sets font-size: 16px for all inputs; .stepper-input explicitly sets font-size: 16px (line 1869)

Score: 5/5 truths verified

Required Artifacts

Artifact Expected Status Details
/src/components/StepperInput.jsx Base stepper component with ±/input/suffix ✓ VERIFIED 90 lines, complete implementation with min/max validation, step control, suffix support
/src/components/WeightInput.jsx Weight wrapper with 2.5kg step and "kg" suffix ✓ VERIFIED 19 lines, properly configured StepperInput wrapper with step={2.5}, suffix="kg", min={0}
/src/components/RepsInput.jsx Reps wrapper with 1-rep step ✓ VERIFIED 19 lines, properly configured StepperInput wrapper with step={1}, min={0}
/src/App.css - stepper styles Input sizing (16px font, 44px buttons) ✓ VERIFIED Lines 1776-1913 provide complete styling for stepper with accessibility rules
/src/pages/WorkoutPage.jsx Integration of WeightInput & RepsInput ✓ VERIFIED Lines 3-4 import; lines 329-337 render with proper onChange handlers
From To Via Status Details
WorkoutPage.jsx WeightInput import (line 3) + render (line 329) ✓ WIRED Component imported and actively rendered in set logging UI
WorkoutPage.jsx RepsInput import (line 4) + render (line 334) ✓ WIRED Component imported and actively rendered in set logging UI
WeightInput.jsx StepperInput import (line 1) + render (line 5) ✓ WIRED Wrapper properly delegates to base component
RepsInput.jsx StepperInput import (line 1) + render (line 5) ✓ WIRED Wrapper properly delegates to base component
StepperInput User input → onChange handleInputChange (lines 13-28) ✓ WIRED Text input with full validation piped to parent onChange
StepperInput +/- buttons → Handler handleIncrement/Decrement (lines 30-42) ✓ WIRED Buttons call handlers that compute new values and trigger onChange
onChange handlers State update WorkoutPage setSetInputs (lines 277-282) ✓ WIRED Changes flow to parent component state management
State → UI Display updated values setInputs[setNum] (line 324) ✓ WIRED State changes reflect in rendered input values

Anti-Patterns Found

No blockers detected.

Inspection of key files:

  • /src/components/StepperInput.jsx: Complete, substantive implementation
  • /src/components/WeightInput.jsx: No stubs or placeholders
  • /src/components/RepsInput.jsx: No stubs or placeholders
  • /src/App.css: All required accessibility and sizing rules present (no TODO/FIXME)
  • /src/pages/WorkoutPage.jsx: Full integration with proper state management

Requirements Satisfaction

All 5 success criteria from ROADMAP.md satisfied:

  1. ✓ Weight field shows "kg" unit suffix visibly inside or adjacent to the input
  2. ✓ Tapping + or - on weight steps by 2.5kg; tapping + or - on reps steps by 1
  3. ✓ Weight and reps inputs reject negative values — typing or stepping below 0 is blocked
  4. ✓ All input fields and action buttons are at least 44px tall and usable with one thumb
  5. ✓ Input font size is at least 16px so iOS does not auto-zoom the page on focus

Summary

Phase 01 goal is fully achieved. The input UX is complete with:

  • StepperInput: Reusable component with validation, stepping, min/max constraints, and optional suffix display
  • WeightInput: Configured for 2.5kg increments with "kg" suffix
  • RepsInput: Configured for 1-rep increments
  • CSS: Accessibility-first sizing (44px minimum touch targets on desktop, 48px on mobile) with 16px font to prevent iOS auto-zoom
  • Integration: Fully wired in WorkoutPage for exercise logging

All artifacts exist, are substantive (not stubs), and are properly wired. Users can quickly log weight and reps on mobile without fighting unresponsive or inaccessible inputs.
