2026 Comparison
You don't need a $100/year subscription to keep your pool clean. Here's what to look for in a pool app, and why most of them are trying to sell you stuff you don't need.
There are dozens of pool apps out there, but most fall into one of two traps: they're either glorified product catalogs from chemical companies, or they're bloated with features you'll never use and charge a monthly subscription for the privilege. A good pool app should do a few things really well:
Based on your actual pool volume, not a one-size-fits-all chart. It should account for pool shape, surface type, and sanitizer method.
If the app only recommends its own brand, it's an ad, not a tool. You should be able to use whatever chemicals you want.
You test your water at the pool, not at your desk. The app needs to be fast, mobile-friendly, and easy to use with wet hands.
Pool ownership is expensive enough. A good pool app should have a generous free tier and, if it charges, do so once, not every month.
