About
Pay once for Pro. No subscription, no ads, no account. Works offline. 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. Free download with a 2-day full-feature trial. $6.99 one-time unlocks Saline Pro permanently — no subscription, no ads, no account, no cloud. Privacy: Saline collects nothing. No analytics, no accounts, no network requests. Your settings live on your device.
