## Most critical reviews (9 lowest-rated)

### 1/5 — Requires In-App Purchase

*2021-09-12*

It claims to be a free app but it requires an in-app purchase right out the gate to even work.

### 1/5 — App freezes and crashes constantly

*2021-01-21*

Not really a calculator as it crashes or freezes doing basic calculations. It also freezes entirely trying to open the settings pane. Takes much too long to open. 

Built in calculator on the phone is much better.

### 1/5 — Crashes Before it Even Opens

*2020-12-16*

I think the title of this review pretty much sums it up. This is not an app, it’s an icon that you can put on your phone to click on when you’re feeling bored and want to see it fail to even load a startup page. 

I the developers’ reply to the other review about constant crashing particularly amusing. To paraphrase, “Just because its response to an unexpected scenario (unexpected by the developers, that is, since it clearly wasn’t unexpected by the other reviewers, 100% of whom encountered it during routine use) is to simply crash, does that make it a rubbish app?” Yeah, I think that’s pretty much the definition of a rubbish app. Either get your act together or at least learn how to gracefully accept your mistakes. It’s called being an adult.

### 1/5 — Just immediately crashed. Also, no help or other information

*2020-10-17*

It just fires up with its UI. There’s no Help or any other way that I can see to learn what this can *do*.

First thing I did when I started it was type in x = 3y. It offered a graph option. I tapped that and it crashed.

Every time, it does this. This app is rubbish.

**Developer response:** Hello,
I agree with you that a help section might be needed for more advanced functions.

Concerning the graph, the = sign in Euclid tells the app to draw 2 different functions (ex: x=2x will show 2 different lines). Because in the second expression, Euclid couldn't really understand what was happening, it crashed. It's a known bug that I'll try to fix!

I'm sorry that you don't like Euclid. Does that particular issue makes it a rubbish app though?

### 2/5 — Unintuitive and uncustomizable

*2024-02-11*

It doesn’t even use the standard calculator layout, causing me to hit comma instead of period constantly. Why is it even there when comma decimals are off?

It took me ages to figure out how to get the result of my calculations, and I’m not sure what I did that caused the answer to begin showing up. I just want a calculator app that works like the default Android one. Bonus points for Speedcrunch/Numbat style features, but entirely unnecessary.

### 4/5 — Decent

*2022-04-01*

Powerful, but there is 1 bug and a UI/UX opportunity. When the display is full, adding new characters does not scroll visually, but logically it did. Thus, one need to move to the left to refresh, even though the new characters are on the right. This is known as happened on Mac but fixed already. 

Overall, the UI could be improved by allowing gestures instead of relying solely on the arrows, and adding landscape support with the additional buttons.

### 5/5 — Review botted?

*2021-12-18*

Using this through my set app subscription and have had none of the issues from previous reviews.

### 5/5 — Brilliant app

*2020-11-15*

This app is brilliant. The design is really well thought out and executed - the conversions in particular are brilliant. 

Thanks for making a great app!

### 5/5 — Superbe calculatrice ! 👏

*2020-10-07*

Très simple d’utilisation, l’application est très esthétique. 

Elle est aussi personnalisable au niveau des couleurs et l’outil de conversion est très utile. 

Bon point également pour l’intégration des graphiques, la fonction de partage est aussi très pratique.
