## Most critical reviews (3 lowest-rated)

### 1/5 — Impossible to use

*2026-08-09*

It won’t let you register for an account. The app is useless.

### 1/5 — Trash

*2024-11-19*

This app is absolutely abysmal. The previous app sucked and they managed to make one worse. Much less user friendly. Honestly would love to know what they did and how much these people are getting paid to put this product out there…

### 2/5 — New app needs help

*2025-10-31*

The product this monitors is only a few months old. Maybe July 2025. The app has bugs. I see no room and water temp data from 9/30/25 to 10/19/25, data 10/20/25 and nothing thereafter. Plus the water level graph is too small to measure. It never changes. Other issues. I see reviews are truncated so no point in going further.
