## Most critical reviews (3 lowest-rated)

### 1/5 — The user

*2017-05-18, version 2.0*

For trig functions, I have tried every entry sequence I can think of, but cannot get it to give the correct answer. I am aware of the degrees/radians choice and that is not the problem. Also what is the "f 0.00" choice for?

**Developer response:** For a trig function, enter the number and then press the desired function.  f 0.00 fixes the number of decimal places.

### 2/5 — bug

*2013-08-03, version 1.0*

Seems to have a bug where the second press of the decimal key doesn't register.

**Developer response:** There can only be one decimal point in a number, so if the decimal point is pressed a second time it is ignored.

### 4/5 — RPN on the phone

*2020-05-18, version 3.0*

I got this calculator for my phone simply because I strongly prefer RPN logic, since it’s what I’ve used all my life; I always mess up what to punch when on regular calculators, plus I find it easier to tack on unplanned numbers to calculate. I only use it for arithmetic functions, so I can’t attest to higher level math functions, but for my simple use I’ve been happy with this calculator.
