1.25.1
2024-03-04
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
1.24.1
2023-11-29
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
1.23.2
2023-07-21
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
1.22.2
2023-06-08
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
1.21.1

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
1.20.0
2023-02-12
The keyboard is so fundamental to TechniCalc, it only makes sense you’d be able to customise it. You can now design your own keyboard layout in a way that makes sense for how you use it. A new keyboard editor lets you drag and drop buttons and create submenus in whatever makes sense for you. You can continue to use the default advanced layout, in addition to a new simplified layout - which drops a few advanced features to make more common features faster to access
Pressing and holding on the previous/next buttons will start fine cursor placement. You can also use two fingers anywhere on the keyboard to do the same thing
For users from countries with non-English number formats, it’s now possible to choose the decimal and thousands separators
When entering numbers and viewing results in binary, octal, or hexadecimal, digits will now be grouped in to groups of 4 instead of 3
The statistics mode now lets you add headings to each column. In addition, when you press the clear button, you’ll now get to pick between clearing only the data - leaving the number of columns, their titles, and chosen statistics in-tact - or resetting the whole table
Added pre-filled exponents (square, cube, inverse); x-, y-, and z- unit vectors
And finally, some bug fixes. The handling of mixed fractions with superscripts has been improved. The rref function will no longer give ‘internal error’ for some inputs. And lastly, when searching in the constants modal, it will no longer crash if there are no results

2020-10-19
This update lets you add your own equations — with placeholders for where you need to fill stuff in. Once you've set them up, you can add and combine them in the editor.
iPad got even better too. Adding items to your memory, searching for constants, or picking units now come come in from the side and take up less space.
Lastly, adding items to memory is even easier. You can now edit the value as well as the symbol.
Please recycle your formula books responsibly.
