Your pool, figured out

The pool app that tells you exactly what to do, in what order, and why.

What makes Poolably different

No pool app does chemistry guidance correctly. Poolably does.

Step-by-Step Treatment Plans

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.

CYA-Aware Chlorine Targets

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.

Chemical Inventory Tracking

Track your chemical stock. Auto-deduction when you apply treatments. Low-stock alerts before your next trip to the pool store.

100% Independent

We don't sell chemicals. We don't push brands. No ads, no affiliate links. Just honest chemistry and clear guidance.

Maintenance

Pool filter cleaning - sand, cartridge, and DE

Clean your pool filter when pressure climbs 8-10 psi above baseline. Sand filters get backwashed, cartridge filters get hosed, DE filters get recharged.

Pool Calcium Hardness: How to Test, Raise, and Lower It

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 - are they worth it?

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.
