### 1/5 — Bait & Switch

*2019-03-24*

As usual they sucker you in by making it free, then they overwhelm you with ads then if you want to get rid of the ads you have pay. So I just rid of the app.

### 1/5 — Pathetic

*2018-02-23*

Crashed before I finished typing the equation.

**Developer response:** Thank you for reporting this, it is now solved.

### 2/5 — Suché, nudné

*2020-11-05, version 1.16*

Malý displej, málo nastavení, farebné pozadie iba sivé.

### 3/5 — Naja, aber ok für Schüler bis zur 6 Klasse.

*2020-08-02*

Für Techniker schlecht

### 4/5 — Your math is off

*2019-12-22*

267.46+176.97 = 444.4299999999
Really?

And where is the +/- button?
Could you please add a unit conversion calculator as well?

### 5/5 — Favorite calculator app

*2023-06-29, version 1.16*

A lot of helpful new feature, and i like minimalistic design! Seeing and copying, sharing result top 🔝

### 5/5 — Finally!

*2022-04-15*

Had to look all over to find a memory calculator that wasn’t written by retards who never understood 3rd grade math.

### 5/5 — Solid Basic Calculator

*2019-11-18*

This let’s you fully type out multi-expression math problems. It can’t do anything too fancy, it’s just a solid replacement for the basic calculator. 

Also, if you close the app, the previous expressions stay in your history (I’m not sure about restarting the phone though).

### 5/5 — Has best tape feature

*2019-11-16*

Love it

### 5/5 — Love It

*2019-10-01*

### 5/5 — The calculator I was looking for.

*2019-09-07*

This is the calculator I was looking for. I recently subscribed to the ‘removed ads’ version because this is the one calculator app that had the features I was looking for. For example, I can easily see the last inputs because there is a history panel which you can scroll up and down with the swipe of a finger. I also enjoy the ‘last’ button feature that allows me to do calculations in where I can use my previous calculated sum—multiply/subtract/etc it by an even prior sum, easily accessible via the history feed. Thanks.

### 5/5 — Finally no need to rotate.

*2019-07-22*

Thank you for creating the only calculator app that gracefully gives you more options without having to rotate the screen awkwardly. Coming from a TI 83 background, this is perfect for basic scientific calculating needs.

**Developer response:** Good point, thank you. We too believe you shouldn’t need to rotate for advanced functions.

### 5/5 — Exactly what I needed

*2019-02-28*

Most calculators I’ve found here don’t have a suitable memory for accuracy. This shows all of your previous calculations and allows you to  recall both expressions and values. Especially useful if you’re iterating through a series of values.

### 5/5 — Perfect basic calc app

*2018-01-22*

This is a great calculator app with a log of all your calculations that you can reference & reuse. Very much appreciate that it’s free!

### 5/5 — Easiest calculator I’ve ever used

*2018-01-07*

No directions needed. Easy to use
