### 1/5 — Its too confusing

*2025-12-20*

While the idea is nice, the app is structured so I couldn’t figure out how to do anything. Its good that there is a free option, but I still can’t use it - it just doesn’t make sense.

### 1/5 — Scam

*2025-11-16*

Not the real app. DO NOT USE

**Developer response:** It is clearly written in the app description: 
"NOTE: This is a companion app focusing on Apple Watch integration and Lock Screen visibility. For the original features, please use the official apps."

### 5/5 — Excellent 3rd Party Addition

*2025-11-13, version 2.1*

Great app, looks good and it’s very helpful filling in gaps of the 1st party app. The widgets are beautiful.

### 5/5 — Great app and customer support

*2025-11-08, version 2.1*

Very useful app, and responsive customer support. 

Recommend for any iOS user with Aranet.
