This app works ONLY with physical urine ketone test strips. Do NOT scan:
✓ Only scan ACTUAL urine ketone test strips after dipping in urine!
Use clean container or urinate directly on strip
Dip bottom pad (ketone pad) for 1-2 seconds
Tap edge on paper towel to prevent running
CRITICAL! Set a timer. Too early/late = wrong results
Hold against white background and scan
Test first thing in morning - Most accurate results
Use good lighting - Natural daylight or bright LED
White background - Use white paper for accurate color detection
Wait EXACTLY 15 seconds - Set timer! Critical for accuracy
Hold camera steady - 6-8 inches from strip, no shaking
Test consistently - Same time daily for trends
Don't scan random photos - Only works with real strips
Don't wait too long - After 60s colors become inaccurate
Don't scan in dim lighting - Causes wrong readings
Don't use expired strips - Check expiration date
Don't test after drinking water - Diluted urine = false negative
Don't scan other test strips - pH/glucose strips won't work
🎯 Best Times: First morning urine or 3+ hours after eating
💧 Hydration: Heavy water intake dilutes ketones
📸 Camera: Clean lens, use flash if needed, hold horizontally
📊 Track Trends: Look at patterns over days, not single readings
🏃 Exercise: Can temporarily lower urine ketones (body using them!)
