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.
