PoolOS — Modern Pool Control PoolOS is built around four principles: 1. Blistering fast When you tap a circuit, light, pump, or spa control, the app should respond instantly. No staring at a spinner wondering if anything happened. 2. Built for pool owners, not IT people You shouldn’t need to understand networks, relays, protocols, or controller quirks just to turn on your spa. PoolOS tries to handle as much as possible automatically and explain what’s happening when it can’t. 3. Enterprise feel, not glitchy The app should feel calm and trustworthy. No random equipment flicker, no confusing reconnect storms, no dashboard lying about what the hardware is doing, no more "do something and have it undo about 30 seconds later" 4. Trusted information PoolOS treats the controller as the source of truth. It gives you instant feedback, then verifies against the hardware and corrects itself if needed. Take control of your Pentair (and soon others) pool system the way it should have always worked. PoolOS is a fast, clean, and actively maintained replacement for the Pentair ScreenLogic app — built by a pool owner, for pool owners. Why PoolOS? The official ScreenLogic app hasn't seen meaningful updates in years, and it looks like it was developed for the installers, not the user. PoolOS connects to your existing Pentair ScreenLogic controller and delivers a modern, intuitive experience on top of the same protocol — no new hardware required. Weather Watch = Three layers of protection, One app. Weather Watch is built into PoolOS — no separate app, no extra setup. 1) Storm Watch is free for every user. 2) Weather Guard and Lightning Proximity are PoolOS Pro features. Storm Watch: PoolOS monitors the NOAA National Weather Service alert feed for your pool’s county in real time. When a severe weather warning is issued, you get a push notification within seconds — not minutes. Weather Guard: No pool app protects your heat pump. Until now.... Heat pumps lose efficiency — and risk compressor damage — when outdoor temperatures fall below their operating range. The Pentair app will run yours at 38°F without question. PoolOS won’t. Weather Guard is an automatic heat pump protection system that monitors outdoor temperature and prevents your heat pump from running in conditions that waste energy and/or could damage the compressor. Set your threshold once. Weather Guard handles the rest — silently, automatically, and with hysteresis logic that prevents short-cycling. Lightning Proximity (coming soon): is real-time lightning strike tracking with distance-based alerts. Know exactly how close strikes are — not just that a storm is somewhere nearby. Full control of your Pentair EasyTouch, IntelliFlo, IntelliChlor, and UltraTemp systems Fast local network connection Real email support from the developer who uses this app daily Free vs Premium​ I want to be clear about the model. The free app still covers the core pool experience and everything you'd find in your pool management app: monitoring, manual control, schedules, setup, and normal local/remote access through the connection path you already use. The free app also includes Storm Watch, which is a storm alert system. Premium is for cloud-backed intelligence features that require servers and external data sources, like Weather Guard, Lightning Proximity and upcoming - Pump Optimization. Pricing is $8.99/month or $89.99/year, with a 14-day free trial and Family Sharing, and auto-renewal. Privacy Policy https://mypoolos.app/privacy.html Terms of Use (Apple): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Requirements: Pentair ScreenLogic Interface adapter. Jandy and Hayward support coming soon.
