Error codes, dosing calculators, filter guides, route management, chemical safety — all in one free app that works without signal, right at the equipment pad.
PoolLens replaces the stacks of manuals and "let me Google that" moments with fast, offline-cached answers — built specifically for the equipment pad.
Hayward, Pentair, Jandy, iAqualink, Zodiac, Maytronics/Dolphin, Polaris, Kreepy Krauly, Waterway, and more. Full fault code database with root-cause diagnoses and fix steps — searchable by code or brand.
✓ LiveEnter your pool volume and current readings — get exact doses for FC, pH, TA, CH, and CYA. Covers liquid chlorine, Cal-Hypo, Trichlor, muriatic acid, baking soda, Baquacil, and every major brand product.
✓ LiveRectangular, circular, oval, and L-shaped pools. Turnover rate and drain/refill calculations built in. Save your pool volumes for instant reuse on every visit.
✓ LiveBackwash steps, media sizing guides, DE charge calculators, cartridge sizing by sq ft — organized by filter type with tabbed navigation. Troubleshooting for every common issue.
✓ LiveOpening, closing, weekly, and monthly checklists. Tap to check off tasks as you go. Progress tracked per visit, per pool. Never miss a step.
✓ LiveBuild your daily stop list, mark pools done as you go, add custom stops. Visual progress bar shows the day at a glance. Detects stale days so you never run yesterday's route.
✓ LiveSave every pool on your route — volume, shape, filter type, notes. Auto-fills your dosing calculator when you select a pool. Chemistry history logged per visit.
✓ LiveGreen pool? Generate a full multi-step treatment plan from a single reading. SLAM targets auto-calculated from CYA. Drain/refill math included. Never guess the path to clear water.
✓ LiveSalt cell diagnostics, optimal salinity ranges, cell cleaning procedure, troubleshooting low output and high/low salt alarms — covers all major SWG brands.
✓ LiveHandling protocols, PPE requirements, spill response, and incompatibility warnings for every chemical in the toolkit. Critical knowledge offline at every service stop.
✓ LiveEverything — every error code, every calculator, every reference — is cached to your device on first load. Works in mechanical rooms, basements, and zero-bar backyards. Green dot = you're good.
✓ LivePoint your camera at an error code display — PoolLens reads it instantly via AI and pulls the full fault diagnosis, causes, and fix steps in seconds. Works online or offline.
✓ LivePoint your camera at any pool part — pump impeller, filter grid, salt cell, valve, O-ring — and PartSnap identifies the manufacturer, model, OEM part number, and what to search online to order it.
✓ LivePoolLens is a PWA — a website that behaves like an app. No app store required, no account, no credit card.
On any phone, tablet, or laptop. No download, no login. Just open the URL and you're in.
iOS: Share → Add to Home Screen. Android: tap the browser menu → Install App. It'll look and feel like a native app — icon, full-screen, no browser chrome.
Enter each pool on your route — name, volume, shape, filter type. They're saved to your device. Every subsequent visit, just pick the pool and the calculators pre-fill.
After the first load, PoolLens caches everything to your device. Pull the error code reference at a garage panel with no signal. Run the SLAM calculator in a basement equipment room. It just works.
The big platforms are built for office managers billing hours. PoolLens is built for the tech at the equipment pad.

* Skimmer pricing per pool/mo as of 2024. Pool Brain pricing per tech/mo. PoolLens does not compete with billing — we complement it.
The feature no one else has built: point your camera at any error display, fault code panel, or equipment label — and get the full diagnosis in seconds.
Aim at the display — PoolLens reads the fault code and pulls root cause + fix steps instantly. No typing, no Googling.
Snap your test strip — get immediate chemical readings fed directly into the dosing calculator.
Photo an unknown part — get the manufacturer, model number, and compatible replacements. No more mystery impellers.
AI scanning feature coming in the next release
Real feedback from service professionals who use PoolLens poolside every day.
"Had a Pentair MasterTemp throwing a code I'd never seen. Pulled up PoolLens while the customer was standing there — had the diagnosis and fix steps in 10 seconds. Looked like a hero."
"I've been doing this 11 years. Still use it every time I open a pool in spring — the chemical sequence, the DE charge calc, all of it. And it works in my customer's equipment room with zero signal."
"We use Skimmer for billing, but every tech on my crew has PoolLens open all day. It's the reference layer those platforms never built. Game changer for new hires."
The pool industry already charges enough. PoolLens is free because great field tools should be free.
The pool industry trains new techs with a 2–4 week ride-along and tribal knowledge. No structured curriculum. No standard protocol. 21,000+ new techs enter the field every year with no consistent training tool.
Daily 5-minute micro-lessons on the standard service workflow: skim, brush, vacuum, test, treat, document. Checklists techs tap through at each stop.
Branching decision-tree scenarios based on real test readings. "Your pool is cloudy. FAC reads OK. Walk through this." — the thing the ride-along was supposed to teach.
Quick-access equipment lookup built into the same tool the tech already uses. Common pump codes, heater lockouts, salt cell diagnostics — on-route, not in a binder.
Algae ID visual guide, green pool recovery, phosphate management, salt pool acid demand — the edge cases that break a new tech's first season.
Pricing: Free for individual techs (weeks 1–2) · $49–$99/mo company license for up to 15 trainees · $29 CPO prep module
Use PoolLens Free Today →No catch. PoolLens is a free reference tool for pool technicians. No ads, no freemium upsell, no account required. We built it because good field tools should be free. The AI scanning feature will remain free when it ships.
When you first open PoolLens, the service worker caches the entire app — all JavaScript, all error code data, all reference tables — to your device. From that point forward, you don't need internet. The green dot in the header confirms you're running offline-capable. Works in basements, underground equipment rooms, rural backyards — anywhere.
No. Those are service management platforms — billing, invoicing, customer CRM, route optimization. PoolLens is a field reference tool — error codes, dosing, filter guides. They're complementary. Many techs use Skimmer for their business and PoolLens for poolside reference. We intentionally don't do billing.
Open poolens.pages.dev in Safari (iOS) or Chrome (Android). On iOS: tap the Share icon → Add to Home Screen. On Android: tap the browser menu → Install App. Takes about 5 seconds. You'll get a home screen icon and full-screen mode — just like a native app, no App Store required.
Hayward (TriStar, Super Pump, MasterTemp, OmniLogic), Pentair (IntelliFlow, IntelliFlo, MasterTemp, EasyTouch), Jandy (iAqualink, JXi), Zodiac, Maytronics/Dolphin (robot cleaners), Polaris, Kreepy Krauly, Waterway, and more. We're continuously adding codes — Beatbot and Betta robotic cleaners are in the current expansion.
Two modes are live now. Error Scan: point your camera at any error code display — Hayward, Pentair, Jandy, Maytronics, and more — and the AI reads the code and returns the full fault diagnosis, likely causes, and fix steps in seconds. PartSnap: point at any pool part and the AI identifies the manufacturer, model, OEM part number, condition assessment, and what search terms to use to find it online. Both modes have an offline fallback using your device's native text detection when you don't have signal.
100%. Your pool profiles, chemistry history, and route data live entirely on your device in localStorage. Nothing is transmitted to any server. There's no account, no backend sync, no data collection. Your customer data is yours.
