Splash is the iOS chemistry assistant for chlorinated freshwater pool owners. Enter your test readings — free chlorine, pH, total alkalinity, calcium hardness, cyanuric acid, water temperature — and get exact doses scaled to your pool volume. Source-aware: pick your chlorine source (trichlor tablets, cal hypo, dichlor, liquid bleach) and Splash factors how each one moves CYA and CH alongside the chlorine.
Why source-aware matters: every pound of trichlor tabs adds about 6 ppm of cyanuric acid to a 10,000-gallon pool. Most pool apps recommend "shock with trichlor" without forecasting where your CYA will be in eight weeks. Splash projects CYA forward based on your dose history and warns you before the pool chlorine-locks.
