Reading Review — Keep sample source and retest notes together in a concise, shareable handoff. Sources & Safety — Open current CDC home pool testing guidance and the Model Aquatic Health Code directly from Settings. Camera reliability — Updated camera rotation handling and corrected torch-off behavior for modern iOS releases. Submission polish — Refreshed screenshots and metadata now show the current app flow.

Retest Plan now appears after every result with a next test window, priority reagent, confidence notes, and follow-up steps.

What's New in Striprate 1.2 Pool type - Freshwater, Saltwater, and Spa - A new Pool Type setting in Settings lets you tell Striprate what kind of water you're working with. Saltwater (SWG) pools get a reminder to check salt cell output before adding supplemental chlorine. Spas and hot tubs automatically switch to the CDC-recommended 3-5 ppm Free Chlorine range (vs. 1-3 ppm for a regular pool), so the status indicators and dose recommendations are calibrated for your specific water body, not just a generic pool. Changing Pool Type also resets the targets to the correct defaults automatically. Export test log as CSV - Tap the share button in the Log tab to export your entire reading history as a comma-separated CSV file. The export includes date, pool gallons, pool type, pH, Free Chlorine, Total Alkalinity, status labels, average confidence, and notes - ready to attach to an email, open in Numbers or Excel, or send to your pool service. Metric units now actually work - The "Show metric units" toggle in Settings previously changed the label but left doses in US units. It now converts every dose to metric: fluid volumes become mL / L, and dry weights become g / kg. Amounts are automatically scaled to the most readable unit (e.g. "237 mL" rather than "0.237 L").

What's New in Striprate 1.1 Trends tab — See pH, Free Chlorine, and Total Alkalinity plotted over your last 30 readings. An ideal-range band highlights drift at a glance, and a Rising / Falling / Stable label tells you where each parameter is heading before it leaves safe territory. Add This First — After a scan, tap "Add This First" to get an ordered action plan for your chemicals. Striprate sequences adjustments in the correct Pool & Hot Tub Alliance order (Total Alkalinity → pH → Chlorine) and tells you exactly how long to wait with the pump running between each addition so the chemistry actually holds. Water Balance Score (LSI) — Tap "Balance Score" on any result to compute a Langelier Saturation Index from your strip reading plus a water-temperature slider and calcium-hardness input. Scores outside ±0.30 indicate water that is eroding your plaster or depositing scale — a pro indicator that no basic strip reader shows. Liquid chlorine preference now works — The "Prefer liquid chlorine" setting in Settings now correctly changes the dose recommendation from granular cal hypo to 10% liquid sodium hypochlorite and recalculates the amount in fluid ounces.
