## Most critical reviews (5 lowest-rated)

### 5/5 — Excellent accuracy

*2026-05-29*

Just a great app all around really. I use this for my pool and it’s incredibly accurate and I love the recommendations. It’s nice how it tells you what to do first this is something that’s always stumped me when I’m dealing with multiple things.

**Developer response:** Thank you for the kind words and 5-star review. We hope you are still enjoying using the app!

### 5/5 — Awesome app!

*2026-05-29*

PoolFu helps enormously with my pool maintenance, and I love that it actually explains the why behind everything. Thank you for making it so good!

### 5/5 — Gamechanger

*2026-05-28*

I just switched from another pool calculator app. First big difference I see is the UI is designed really well. I use Poolfu for both my pool and hot tub, and the recommendations are on point. It took me a little getting used to, but so far I’m very happy with this app.

### 5/5 — Great Spa Testing App!

*2026-05-22*

This app has been amazing and has exceeded my expectations. I use it when testing my hot tub, I log the results and follow the guidance. It tells me exactly what’s required and how to balance the water correctly. So easy to use and follow, and it’s great having all of the spa information and test history in one place. The achievements awarded in the app are fun too, thanks Splash! ;)

### 5/5 — Incredibly easy to use, very impressive

*2026-03-23*

I’ve been using this for about a week now and I’m absolutely blown away by it so far. It seems to get every treatment recommendation spot on. Well, worth the subscription.

**Developer response:** Thank you for the kind words and 5-star review. We hope you are still enjoying using the app!
