User reviews

Great app for pool owners!

Really impressed with this app! If you have a pool, you know how frustrating it can be trying to keep all the chemicals balanced. This makes the whole process a lot easier. I really like how it tells you exactly what chemicals to add and how much, instead of having to figure it all out yourself. It’s simple to use, easy to understand, and takes a lot of the guesswork out of maintaining a pool. Definitely worth checking out!

Awesome

Excellent app. Poolcoach takes the guess work out of pool care. The recommendations are easy to follow and it keeps my salt water pool crystal clear. Definitely worth downloading if you want a simple way to manage your pool.
