### 3/5 — Clearly needs much improvement

*2024-05-31*

I got this app primarily to use my own function that I set up in the app. That part of this calculator is glitchy to the point of being unusable. My function required values of 8 variables to be input. Once I had the function set up (which itself was a chore with this app), I went to use it on my iPhone 23 pro. Well, I could only input values for 4 of the variables while the rest remained somewhere in the lower part of the screen where there was no way to even see them. I deleted the app, downloaded again and repeated the process with the same result. 
So, in short, this app did not serve me at all.

### 5/5 — FANTASTIC STREAMLINED APP!!!!

*2024-05-31*

Minimalist great functioning app with customization capability,fills the need perfectly for quick calculations in everyday life, and then some…

### 1/5 — Unable to enter any values :-(

*2024-05-31*

I'm sure this app used to work as I've created a couple of my own formulas in it however I noticed a while back that when I go to any of them (actually just tested and it's not just my formulas but also all the in-built ones too) I can no longer tap into the text fields and enter any values 😟

This unfortunately makes the app completely unusable. 

I'm on an iPhone 12 Pro Max if that helps at all. 
If you can update it so it starts working again then I'll be able to update my review but at the moment the app unfortunately is essentially useless to me I'm afraid.

### 1/5 — Adds unwanted item in predictive bar

*2023-03-19*

It adds an unwanted item in the predictive bar which persists in text messages and other places when the keyboard is used.  It will not go away, even after deleting the app.

**Developer response:** can you send screenshots in my instagram page @mcktrdev. i will try to fix as soon as possible.

### 4/5 — Core functionality is good, but some UI roughness

*2023-01-03*

The core functionality to easily create formulas and then run them repeatedly is great. A spreadsheet app (Numbers, Sheets, Excel) can provide similar functionality, but with a more cumbersome interface.

UI anomalies:
• Long value prompts prevent the input box from appearing (eg the Gravitational force formula in Physics won’t enable input on iPhone 13 Pro).  
• When editing a formula the automatic variable/function recognition jumps the cursor unexpectedly to the end of the text (eg erasing the variable name “distance” in the middle of a formula will cause the cursor to leap to the end when the automatic function detector sees “distan” and interprets tan as the tan() function.
• inputting the numbers at the bottom of the screen and then seeing the result at the top is a bit strange. Normally UIs flow from the top down.

### 3/5 — I didn't like it.  But I gave it 2 more stars…

*2022-12-09*

The developer took the time to respond so I gave them 2 more stars for answering. 

Maybe I missed it, but there is no "CLEAR" button to erase everything after I have done my calculation. Sorry, better calculators out there. This one has some nice features but without an easy way to erase everything, not worth keeping. Deleting it now. Also, why have all the numbers and operatives at the bottom of the screen and the = sign at the top?? It almost seems like an after thought when programming- "Oh, we need to be able to solve the problem, so let's put the = sign somewhere, but not in a good spot".

**Developer response:** We will add the “clear” button in future updates. The reason why the “=” key is above is actually this program is designed to run saved formulas. Calculator feature was added later. I couldn't understand why you were so offensive when giving feedback. Thanks for your feedback anyway.

### 2/5 — Idea is good, however…

*2022-12-07*

…however, the very first operation that I tried to make was F to C degree conversion, and the interface doesn’t accept negative numbers. The keypad does not “think” you would ever need to convert negative temperatures.

Plus, the calculator interface in general looks confusing, not too friendly.

**Developer response:** We will fix keyboard immediately. Thanks for your feedback, we will consider your opinion for upcoming updates.

### 2/5 — No decimal point on the app keyboard

*2022-12-07*

This would be a great app, but I can’t believe it hasn’t got a decimal point input on the app inbuilt keyboard in physics and maths mode (and probably other modes).

**Developer response:** We will fix keyboard immediately. Thanks for your feedback, we will consider your opinion for upcoming updates.

### 1/5 — Please review your code.

*2022-10-13*

Once a Function is created , if you delete it and start creating it again , the original function variables keep appearing even although you have changed them. Very very frustrating.

**Developer response:** Are you experiencing this error with preloaded functions? Because I couldn't see this problem in newly created formulas. I would appreciate if you take a video and send it to our email support page.
