The pool app that tells you exactly what to do, in what order, and why.
No pool app does chemistry guidance correctly. Poolably does.
Enter your test results. Get a numbered plan: what to add, how much, in what order, and why. Not just a calculator — an expert system.
Your CYA is 80? You need FC of 6–8, not the generic ‘1–3 ppm’ every pamphlet says. Poolably adjusts based on your actual stabilizer level.
Track your chemical stock. Auto-deduction when you apply treatments. Low-stock alerts before your next trip to the pool store.
We don't sell chemicals. We don't push brands. No ads, no affiliate links. Just honest chemistry and clear guidance.
Pool chemistry guides, maintenance tips, and seasonal checklists.
Clean your pool filter when pressure climbs 8-10 psi above baseline. Sand filters get backwashed, cartridge filters get hosed, DE filters get recharged.
Calcium hardness should sit between 200 and 400 ppm for most pools. Too low and your plaster dissolves; too high and you get white scale on tile, heater coils, and salt cells.
Digital pool water testers read free chlorine and pH within 5% of a Taylor K-2006, but most struggle on CYA and none tell you how much chemical to add next.
Free calculator with treatment plans, 1 pool, and 30-day history. Upgrade to Pro for unlimited pools, full history, inventory tracking, and more.
