## Most critical reviews (7 lowest-rated)

### 1/5 — Incorrect compared to other calculators

*2022-01-30*

Off by between 5-10 kts.  Not reliable

### 3/5 — No way to choose between F and C?

*2021-08-22*

Is there really no way to change between Celsius and Fahrenheit? That makes it so you need another app to convert temperature. Am I missing something? This seems like a major oversight.

### 4/5 — How do u change to mph

*2024-09-05*

I can’t find how to change knots to miles per hour which my airspeed indicator is calibrated in?

### 5/5 — Well Done

*2024-01-01*

Thank you.   Both of your apps are absolutely perfect.  Thank you.

### 5/5 — Works as stated. Generous contributor to the flight testing and experimental community.

*2023-05-13*

Another useful offering by Mr. Petty. Thank you sir. I’m enjoying tinkering with Benchmark too. As for the one user saying there is no way to change units; there is. Tap the little “i” in the corner and drill down. As for the other claiming the app is inaccurate, if you mix up C and F, you get a big error (10 knots on a sample I just did).

### 5/5 — Simple but lacking unit selection

*2020-07-11*

Simple app very easy to use. That is exactly what I was looking for.

### 5/5 — Excellent

*2016-06-15*

A great tool - thanks :-)
