Saline is the iOS chemistry assistant for saltwater pool owners. Enter your test readings — free chlorine, pH, total alkalinity, calcium hardness, cyanuric acid, salt, water temperature — and get exact doses scaled to your pool volume. Cell-aware: pick your Hayward TurboCell, Pentair IntelliChlor, or Jandy TruClear and Saline tunes salt targets and recommendations to that specific cell.
Features
• Brand-cited dose math for BioGuard, HTH, Clorox, Pool Essentials, Leslie's, and generics
• Test & Adjust: 7-parameter readings → recommendations with manufacturer-cited dose math
• CSI (Calcium Saturation Index) calculation — the metric that predicts SWG cell longevity
• SWG-specific FC/CYA guidance — 5 % ratio, not the 7.5 % manual-chlorine rule
• Borates calculator — TFP's recommended pH-stabilizer that most pool apps ignore
• Salt addition calculator with cell-brand-specific targets
• Named-source citations: Trouble Free Pool wiki, manufacturer documentation
• Universal app for iPhone and iPad
For pool owners who don't want to memorize forum threads. SWG (saltwater) pools 8,000–60,000 gallons.
