StripVision: AI Water Test

StripVision reads water test strips with your iPhone camera and turns pad colors into precise ppm values in seconds. Stop squinting at printed charts in poor lighting. Place your test strip next to its bottle chart, and StripVision measures colors with scientific precision, corrects for ambient lighting, and gives you the exact measurement number — or tells you honestly if the strip could not be reliably verified. NEW IN VERSION 1.2 • 3-Second Kinetic Video Scan: Captures multiple temporal frames to eliminate single-frame glare and sensor noise. • 3D Tilt Leveler: On-screen gyro-level ensures your phone stays flat over the strip for uniform illumination. • Haptic Reaction Timer: Visual and vibration countdown prompts you to photograph the strip at the exact reaction second specified by the strip manufacturer. • Smart Single-to-Panel Detection: Photographing a single-pad strip in 7-in-1 mode is automatically recognized and redirected without error. • Quota Shield: Failed or unreadable photos never consume your scan quota. • Reminders & History: Set re-test reminders and track long-term chemical trends with interactive charts. HOW THE SCIENCE WORKS • Laboratory Color Space: Converts RGB camera sensor pixels into perceptual CIELAB (L*a*b*) space. • Ambient Illumination Compensation: Estimates illuminant color temperature (D65 daylight, cool LED, warm fluorescent) and balances shadows and reflections. • Dual-Engine Fusion: Cheung 2004 polynomial regression cross-checks against a fine-tuned vision AI model. • 5-Stage Optical Quality Gates: Validates framing, glare index, delta-E distance, confidence, and chemical ordering. SUPPORTED TEST TYPES • Swimming Pools & Spas: Free Chlorine, Total Chlorine, Bromine, pH, Total Alkalinity, Cyanuric Acid, Total Hardness. • Aquariums & Aquaculture: Nitrite (NO2), Nitrate (NO3), pH, General Hardness (GH), Carbonate Hardness (KH). • Drinking Water & Wells: Total Hardness, Residual Chlorine, Iron (Fe), pH. • Commercial & Industrial: Chlorine Dioxide (ClO2), Disinfection residual monitoring.
