Why PoolFu Is Simple
Simply Clear & Safe Water.
Pool care is only difficult when every reading is considered in isolation. PoolFu keeps the work simple by reading your chemistry as one connected body of water.
A simple pool dosing app.
PoolFu calculates exact chemical doses for your water temperature, stabilizer level, pool surface, and the products you actually use.
Plain-English explanations.
It explains what is happening when you want to learn, and gives you a direct next step when you just want the pool fixed.
Guidance for your pool.
Your equipment, surface, volume, location, weather, and test history all shape the recommendation you see.
Simple, Not Shallow
The chemistry depth stays under the hood.
pH affects chlorine. Stabilizer changes your chlorine target. Temperature shifts water balance and chlorine demand. PoolFu's Chemistry Engine and Unity Framework handle those interactions for you, then show the clean version.
- Dynamic chlorine targets based on your stabilizer level.
- Temperature-aware water balance that adjusts to your conditions.
- Equipment-first guidance for saltwater pools and real pool setups.
