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

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.

Graphing has been in beta for some time users wanting to brave it, but today, it makes its prime-time debut. You can add up to eight equations to plot all your ellipses, quadratics, trigonometric functions, or any other equations you may have. Every equation can be customised to change the colour and line width. Once you’ve added them all, you and pinch and pan around to see how each equation changes over the x and y axes A new onboarding screen lets new users quickly choose the most common settings when starting the app for the first time. You can pick the theme, the keyboard layout, and the number formatting Equations provide a quick way to insert a pre-written equation into your current input. Now, you can insert your equations using a function representation. When using this optional mode, your equation placeholders will be converted into the function parameters, and duplicated placeholders will be collapsed into a single function parameter. This provides a much more compact representation, and speeds up filling in equations The units conversion screen has been improved to simplify the most common actions. By default selecting new units will replace all units. It is, of course, still possible to add, edit, and delete individual units through a new advanced edit mode Keyboard navigation has been further improved throughout the app. You can now press enter in the modals for adding custom constants, variables, equations, or graphing equations to submit them To match the iOS and iPadOS counterparts, the macOS app can now set the theme to always be light or dark, overriding the system theme

The graphing mode has been completely reworked to support graphing multiple equations at the same time. You can now display up to eight equations simultaneously, with each equation being displayed in a different colour. Additionally, it is now possible to use variables in your graphed equations In a similar fashion, the currency converter now allows converting multiple to currencies at the same time. Changing the input will give the conversions for as many currencies as you need

Graphing has been asked for a lot - and today, it makes its debut! You can plot equations using both x and y, graph areas using greater than and less than operators, and pinch and zoom on the graph International users can now input decimal separators using the comma on their hardware keyboard instead of the period, and add undo and redo as keyboard swipe gestures When setting symbols for constants or variables, you can now use the hardware keyboard The built-in NIST have been updated to their latest values

Currency conversion has long been a highly requested feature - and today, it makes its way to TechniCalc. The new currency conversion mode allows you to convert between 57 currencies with the latest exchange rates. You can find currencies grouped by their geographical region, or use the search feature Unit conversions have undergone a significant enhancement. Previously, the standard editor allowed advanced unit-related mathematical operations but lacked the ability to convert units. On the other hand, the unit converter offered a simpler interface - so only accepted basic inputs - but was the only way to convert units. Now, the standard editor now has parity with the unit converter. When you do unit-related maths, you’ll be able to convert the output into both regular units (e.g. square inches), or composite inches (e.g. feet and inches). You’ll also be able to input composite units into the standard editor too - i.e. 1 ft 3 in. Lastly, PSI (pounds per square inch) has been added to the list of units Several adjustments have been made to the interface. Both input and output sizes have been increased, reflecting the bigger phones of today. Additionally, the live result's appearance has been refined to seamlessly integrate with the surrounding content. The live result is also enabled by default now Undo and redo is now supported using the standard system gestures - either a three finger swipe backwards/forwards on the input, or shake the device. In addition, the current state of each editor will now be preserved when switching back and forth between them There’s also a fix to a memory leak with long-running equations

The hexadecimal digits (A-F) will now be hidden until you start entering a hexadecimal number with the 0x character. Additionally, when entering digits in binary (0b) and octal (0o), the digits outside of the base will be disabled. Sorting items in equations, variables, history etc. will no longer have the sorting reset when adding new items

The popups throughout the app (modals if you’re technical) have a had their design updated, and now includes the system swipe-down-to-dismiss gesture in many cases Some icons have been redesigned The output for solvers has been updated. You can now copy results to the standard editor to do further computations on. And like the standard editor, it now will also indicate the angle mode used for computation if it would have had an effect the outcome The submit button will provide a shortcut to jump to all placeholders, rather than just placeholders from inserted equations. Pressing tab on your hardware keyboard will now tab between placeholders Pressing and holding on the fraction button will now move some characters before and after the cursor into the newly created fraction There were a few performance improvements in the syncing data, and when updating variables Favourite unit conversions will now be grouped by their dimensions Lastly, there were a few bug fixes. The physical keyboard will now work again in the unit converter, the add constants screen, the add variable screen, and the add equations screen. When searching for units, it will no longer show a completely blank screen when no units matched the search query

The unit converter gained a new ‘favourites’ section where you can add the units you use most frequently When converting from multiple units to a single unit (e.g. feet and inches to meters), the meters will no longer be rounded down to the nearest whole number Multiplication and division by units will now simplify if there are overlapping units On macOS and iPads with a keyboard, you can insert units using the keyboard; and search constants by their symbol (e.g. ‘hbar’ for Plank’s constant, or rk90 for the Von Klitzing constant) When outputting to other bases, the exponents will now be in the base, rather than base 10 Finally - some bug fixes. In the rare case that we cannot display an equation, it’ll show an error rather than turning blank. Fixed a crash if you moved your finger at exactly the right time while interacting with the keyboard - you had a window of a few milliseconds to trigger this crash, and it was only seen once. Pressing tab on macOS will no longer stop the keyboard from working. The example for equations has been updated. The cosec button appeared twice, instead of one of the instances being sec

Fixes the equation input turning blank for some (extreme) inputs

The unit capabilities in TechniCalc have seen their biggest overhaul since it launched. You can now add units within the standard editor, and mix and match them. For example you could write, (1 mi + 300 ft) / (1 min + 30 s), and get 18.9 m/s. You could then move this result directly to the unit converter and convert this to 68 km/h. The new unit capabilities are deeply integrated with the rest of the app, and all built-in scientific constants can be used with their units You can now choose to force dark or light mode instead of what’s set in system settings There’s a new shortcut to auto fill the repeated placeholders in equations. After you’ve filled in a value for the first placeholder, placing the cursor on any subsequent placeholders will show a tooltip to fill in the first value When adding a matrix, unfilled elements will default to zero, making it much quicker to fill in some larger matrices You can now re-order your custom constants, equations, and variables Added 95% confidence interval to statistics mode Improved output quality when copying equations as MathML Then lastly, a lot bugs were squashed. Calling a function with a negative number (e.g. sin -1) wouldn’t parse. The input was empty when you opened a shared TechniCalc link. There were a few layout issues that happened in various menus when using an iPhone in landscape orientation. Placeholders were erroneously added when adding a new equation. Tapping on links in the reference section would crash the app. There was a battery drain issue when cancelling a long-running computation
