## Most critical reviews (3 lowest-rated)

### 1/5 — Don’t buy

*2023-06-08*

Completely useless. You’d do better with a google search for formulas, especially considering it’s not a free app.

### 1/5 — NDT app

*2022-06-01*

This app is useless, better to use the calculator that comes with the phone.

**Developer response:** Sorry to hear it wasn't helpful! We focused on equations that would be beneficial for inspectors, welders, and anyone else needing ultrasonic formulas. 

I added my email at the bottom of the app (kblack0610@gmail.com), please let me know of any improvements that would be beneficial to you!

### 3/5 — Why is there ads?

*2022-09-28*

Good app. Does what it says and easy to use. However, ads are annoying and unnecessary especially when the app is priced over £7. 

Remove the ads and a full 5 stars would be worthy. The ads just take up so much screen.
