Striprate is an offline pool and spa test-strip companion for fast pH, free chlorine, and total alkalinity checks. Dip a compatible generic three-pad strip, frame the pads inside the on-screen guide, and tap Read. Striprate samples pad colors on device, matches them to bundled chart values, and creates water-care estimates scaled to the pool volume and targets you enter. Manual entry is available when lighting or camera conditions are not suitable. WHAT STRIPRATE DOES - Reads compatible generic three-pad pH, free chlorine, and total alkalinity strips - Samples each pad color from the live camera frame on device - Includes manual entry and a built-in sample reading - Matches bundled values for pH 6.2-8.0, free chlorine 0-10 ppm, and total alkalinity 0-240 ppm - Scales displayed adjustment estimates to the pool volume and targets you enter - Supports freshwater pools, saltwater pools, and spas - Lets you override a pad value when the printed strip chart differs - Logs readings with dates, color swatches, notes, and review context - Shows pH, free chlorine, and total alkalinity trends - Exports the local reading log as CSV - Includes sequencing, retest planning, confidence notes, and a water-balance workspace - Adds Reading Review for recording sample source, preserving retest notes, and sharing a concise handoff - Links directly to current CDC home pool testing guidance and the Model Aquatic Health Code PRIVATE BY DESIGN Striprate has no account, no analytics, no tracking, and no developer backend. The camera is used only to sample the three strip pads. Frames are processed live on the device and are not stored or uploaded. Reading history and preferences remain in local app storage unless you choose to export or share them. IMPORTANT SAFETY INFORMATION Displayed values and adjustment amounts are general estimates, not a substitute for the strip or chemical product label, local requirements, or professional water testing. Confirm compatibility and concentration, add chemicals gradually, never mix products, circulate as directed, and retest before another adjustment.
