Pool & spa care with any test kit

Yes. PoolFu does the thinking for you. Enter your test results and the app tells you exactly what to do, step by step, with clear explanations of why each action matters. The chemistry engine handles the complexity. You just follow the guidance. If you ever want to dig deeper, Splash AI is there to answer questions in plain English. You don't need to study pool chemistry. You just need to follow the steps.

PoolFu is built on the Unity Framework, a chemistry framework we developed as a first in the pool industry. At its core is an engine based on Wojtowicz's foundational research, the same thermodynamic relationships and saturation equations that define modern pool chemistry science. Unity ensures every recommendation works together as one integrated system. When the app suggests lowering your pH, it has already checked that advice against your alkalinity, stabilizer level, water temperature, and saturation index. You never receive guidance that contradicts itself. This level of coordination is something many pool professionals don't have access to.

Your Health Score is a single number from 0 to 100 that shows how good your water quality is at a glance. It weighs sanitizer levels most heavily, then pH, then the supporting parameters. A score above 90 means excellent water quality. Below 50 means something needs attention now. For whether it's safe to swim right now, PoolFu gives you a separate, clear answer on your pool's screen. One glance, and you know exactly where you stand.

Yes. PoolFu includes specifications for 616 saltwater generator models from 129 manufacturers, each with model-specific salt targets. When your chlorine runs low, the app suggests adjusting your SWG output percentage first, then extending run time, before ever recommending you add chemicals manually. Your equipment does the work. PoolFu just tells it what to do.

Yes. PoolFu includes a searchable database of 1,721 hot tub models from 167 brands, so your water volume is set automatically when you select your spa. Water-balance targets account for higher temperatures, and bromine support is built in for spa owners who prefer it. Spas even get true spa chlorine targets rather than borrowed pool formulas. And if your spa has a UV, active oxygen (AOP), or nanobubble system, like Jacuzzi CLEARRAY or True Water, tell PoolFu and the chemistry adapts: a lower everyday chlorine target, readings that count as acceptable between soaks, and a friendly reminder to top up before anyone gets in. Same precision, smaller water.

Yes. PoolFu works anywhere in the world. The chemistry engine factors in your local climate and seasonal patterns when calculating recommendations. Whether you're managing a pool in Arizona, Norway, or Singapore, the guidance adapts to your conditions. The app speaks your region's conventions too: Celsius and metric units throughout, comma-as-decimal number entry, and a product catalog with local brands, like Canada's Lawrason's range, dosed the way their labels read. Even spreadsheet exports switch to a format your local Excel opens cleanly. Pool chemistry follows the same science everywhere. Your location just changes what that science needs to account for.

Splash is your on-demand pool chemistry expert, available around the clock. The core app already tells you what to do through the chemistry engine. Splash is there when you want to understand why, or when you have a question the step-by-step guidance doesn't cover. Ask why your pH keeps drifting up, and Splash considers your saltwater generator, your test history, and recent weather before answering. Think of it as having a pool expert in your pocket for the moments when you need more than just instructions.

Yes. PoolFu includes a free 14-day trial with full access to everything in the Homeowner plan, from the chemistry engine to Splash AI. Cancel anytime. After the trial, the Homeowner subscription is $53.99 USD per year, or $5.99 per month if you prefer monthly billing. The annual plan works out to less than half the price of a latte each month. Some pool service companies charge $500 a month for weekly chemistry visits. PoolFu gives you that same level of expertise, built on science most technicians don't have access to, for a fraction of what a single service call would cost.

PoolFu is available on iPhone and iPad. Your pool data syncs across all your Apple devices, so you can log a test on your phone by the pool and review your history on your tablet later. Android support is not available at this time.

Yes, all of it, whenever you want. Every pool and spa can export its full test and treatment history as spreadsheets that open in Excel, Numbers, or Google Sheets, plus a complete backup you can restore into PoolFu later. Send months of history to your pool service in one attachment, straight from the app. Your water, your data.
