Stores all my data from week to week. Calculates how much of each chemical to add and gives me choices on which chemicals I use. ### 1/5 — Unstable *2026-01-02, version 5.5.9* What a useless app. The conversion between gallons and liters are unstable. In the set up I set my pool capacity to 9247 gallons with no option to set it in metric. . While using the calculator I’d have to flick the switch to convert to metric only to find it consistently gave me a pool capacity of 9247 liters not the correct 35000 liters. Do better! ### 3/5 — Update eliminates features and now includes ads. *2025-08-04, version 5.5.4* This used to be a very handy and free app. ### 1/5 — Changes are horrible *2025-08-01, version 5.5.4* Your changes have completely ruined this app. I use this app daily and have all my pools categorized and now everything is missing. I’m OUT ### 5/5 — Simple and smooth *2022-04-15, version 1.0* Use this everyday for work . Super reliable ### 2/5 — No metric system *2021-06-27* No metric system ### 1/5 — Didn’t get past the login screen *2020-12-26, version 1.0* Not sure why a pool chemical calculator app is asking me to register and login. Surely you don’t need to collect my details for this ### 5/5 — Get it *2020-04-14, version 1.0* This is exactly what I need ### 1/5 — Hopeless where is the metic config? *2019-10-04, version 1.0* It uses only imperial units ### 1/5 — Requires an account *2019-06-23, version 1.0* Im looking for a simple calculator to use occasionally. Thought this would be it. However it requires the creation of a user account to use. 1 star for forcing the creation of a user account before being able to use or even test out this app. ## Frequently asked questions about Pool Chem Calculator ### How many pools can I manage with Pool Chem Calculator?
