### 1/5 — Ads

*2024-01-16*

Works as intended but plays an add every lightning strike. Wasting time

### 1/5 — Horrible app with intrusive ads

*2021-08-05*

Just use a web app for this, honestly.

**Developer response:** The app is free. Thats why there is ad. You receive data after ad. You can remove all advertisements with in-app purchase.

### 1/5 — Shame on Apple for allowing this app

*2020-07-05, version 1.04*

The app is just an ad generator. When you click on the thunder button it pops up an ad that can’t be closed and you don’t even get the data. Total scam app.

**Developer response:** The app is free. Thats why there is ad. You receive data after ad. You can remove all advertisements with in-app purchase.

### 5/5 — Nice

*2020-06-16*

I like the map feature to see whereabouts it hit
