## Most critical reviews (10 lowest-rated)

### 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!

### 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

### 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

### 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.

### 2/5 — No metric system

*2021-06-27*

No metric system

### 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.

### 5/5 — Great App!

*2026-07-18, version 5.6.7*

Super easy to use. 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.

### 5/5 — Simple and smooth

*2022-04-15, version 1.0*

Use this everyday for work . Super reliable

### 5/5 — Get it

*2020-04-14, version 1.0*

This is exactly what I need

### 5/5 — Excellent Calculator

*2019-03-16, version 1.0*

App provides a wide variety of calculations to get my pool in shape. There is an integrated weather feature that provides insight on how and what to do to maintain your pool for any condition. Highly recommend this app!
