### 5/5 — Great calculator

*2026-08-07*

Not bad but for 8 buck this was worth a good robust calculator with out a dang ad in sight!!

### 5/5 — Great calculator

*2026-08-02*

Clean, thoughtfully designed calculator, especially handy for scientific purposes, especially when it comes to to units and conversions.

### 2/5 — I want to love this, but it’s unusable.

*2025-11-13*

I made a bit on an impulse decision in buying this calculator - it seemed to be an excellent upgrade from the aging desmos scientific app & the just horrible apple calculator. The features of this app are great, but the interface is scaled terribly. It reacts extremely poorly to being resized, and is completely unusable when not in full screen. 95% of my workflow with a calculator is either in slide over or split screen / windowed mode with another app, and when I try this with TechniCalc, the working space gets squished to the top while the keypad becomes enormous. I also thought the custom keypad layout would solve this, but it just replaces blank spaces with a weird series of dots in the tile. The side bar is massive, the keypad is massive, but the actual calculations themselves are squished against the top of the window. If you’re using matrices, they literally overlap on themselves. If this gets fixed down the line I could love this app and give it another try, but this is so terrible I can’t imagine it has been tested properly on iPad.

**Developer response:** If you reach out to me in email with some screenshots of the issues you’re having, I’d love to try and address them. You can use the ‘contact developer’ link in the bottom section of the sidebar, or the menu on iOS

### 5/5 — Simply amazing, but could use multi lines of history on the top

*2025-11-09*

Quite a good and versatile calculator. The title describes my biggest gripe. One QOL improvement could be a bit of color coding for grouped buttons.

**Developer response:** Thank you! 🤩 I don’t quite follow what your feature suggestion is. Reach out to me via email if you wanted to discuss further - my email is in the app

### 5/5 — Outstanding

*2025-10-11*

I think the world has yet to discover this calculator!

**Developer response:** Thank you 😊

### 5/5 — Fantastic calculator app that is as beautiful as it should be!

*2025-04-29*

This app is beautiful on all my devices. It works fast and smoothly and any function I could need is there. Developer is very responsive too!

**Developer response:** Thank you! 🤩

### 5/5 — Form and Function

*2025-03-09*

This app hits the mark in both UI design and feature set. It's highly extensive and allows for customisation whilst also providing all the features you could want out of the box. It is easy to navigate and intuitive to use. As a bonus the app works very well on all devices, be it Mac, iPhone or iPad. For anyone looking to replace their physical calculator this is the one to look at.

**Developer response:** Thank you 🤩

### 5/5 — Excellent for both technical and basic use

*2025-02-12*

This has become the standard desktop calculator on my Mac. It more than lives up to its name for complicated or technical computations, while remaining quick and easy for basic calculations, so there's never any reason to use anything else! Input is simple, both input and output are formatted beautifully, and the result updates as you type. It's fast, solid, powerful, and pretty much always running somewhere among my open windows.

**Developer response:** Thank you! 🤩

### 5/5 — Feature rich calculator

*2024-12-17*

This is a nice alternative to the stock calculator.  Its’ Apple silicon code runs on iPads, Macs and iPhones (just noting that the developer allows this and doesn’t try and sell 2 versions).  A little more interface customizing and it will be great!

**Developer response:** Thank you for the review 🤩

### 5/5 — Great calculator

*2024-12-13*

This was a great find. a proper scientific calculator that is easy and intuitive to use and feature packed but not in a confusing way. Super easy to get set up and customise to what you are doing. 
The developer is also incredibly quick to respond to comments or help. Much appreciated.

**Developer response:** Thank you for your review 🤩

## Version history (last 5 releases)

### 1.31.1 — 2025-11-09

Small refinements to enable the new Liquid Glass elements

### 1.31.0 — 2025-10-01

Small refinements to enable the new Liquid Glass elements

### 1.30.0 — 2025-07-10

The layout on iPad has been improved. There’s a new set of keyboard icons to make advantage of the bigger screen, and the graphing mode will use up less space to allow for more space for your graphs

When designing a custom keyboard layout to suit your needs, you now have the option to add dedicated buttons for constants, equations, and units. This also means if TechniCalc doesn’t have a function built-in that you need, you can add it to your equations list then the keyboard, and it will feel like a built-in function

In addition to the improvements for custom keyboards, a new ‘Woodworking’ keyboard joins the Simplified and Advanced layouts. This is a simplified keyboard with quick access to units commonly used in joinery

Calculations using units are now more accurate. Additionally, when performing calculations on units in the standard editor, better defaults are used when conversions are necessary. For example, multiplying 10 inches by 2 gives 1 foot 8 inches. Of course, if the defaults aren’t what you need, the output can always be customised to your preferences

Currencies can now be favourited in the currency conversion mode

The statistics mode now supports up to eight columns, and a few additional statistics have been added

Along side the four built-in output styles, you can now configure your own style to suit your preferences

### 1.29.1 — 2024-11-10

Users who have upgraded to iOS 18 will now be able to add a shortcut to TechniCalc in their Control Center or lock screen. The Home Screen icons now also support the dark and tinted variants.

There have been a few tweaks in some of the menus within the app. The history screen will let you insert a previous equation into the current equation. A few lists now have the ability to swipe right for commonly used actions: swiping right on a history item will insert the value, and swiping right on an equations item will insert the equation and open the autofill menu. You can also clear all variables from the dropdown menu.
