### 1/5 — Not worth $1.99

*2024-02-02*

The app is very basic. There is no way to set notifications. You can’t save any locations. There is no available warning system to set. The website has better tools than this.

### 1/5 — Spinning wheel

*2022-12-23*

Not worth it.
Slow, and grahically worthless.

### 1/5 — Unable to open settings

*2018-08-29*

After paying and deleting / reloading app still unable to open settings.

**Developer response:** Please check with the latest app update. The issues should be addressed. Let us know if there is anything we can improve.

### 1/5 — Crashes

*2017-01-13*

The app crashes, useless
