What’s changed.

3.0.1 August 2026

Sign in and the Pro upgrade are now reachable from the opening tour, so a new install is offered both before it finishes.

On iPhone, the composer gained an equals key, the symbol drawer closes by swipe or tap, and a long equation no longer overlaps its own preview.

On Mac, the settings window resizes.

3.0.0 August 2026

Calciq becomes a notebook.

Introducing notebooks. Calculations now live on a page you can name, revisit, and switch between, instead of scrolling away.

Name a value once, write rent = 2400, then use it in every line below. Change the definition and everything that depended on it updates, with the old number struck through so you can see what moved.

Algebra and calculus arrived. Solve equations, take derivatives, and keep exact fractions and radicals rather than rounded decimals. Matrices came too, with determinant, inverse, and solving systems in a grid built for typing.

Every result expands into a receipt showing the steps behind it, and solved equations can be graphed.

Calciq Pro launched. It lifts the workspace and variable limits, searches everything, keeps history forever, and raises the monthly AI allowance. Everything that computes on your device stays free.

2.3.1 July 2026

Chains of plain arithmetic typed after a result, like +500+900, continue your running total on the spot. They no longer needed an internet round trip for basic math.

On Mac, a question that needs AI now offers Sign in with Apple right where you are, and your question continues once you're in.

History shows your most recent calculation at the top again.

2.3.0 July 2026

Time questions answer instantly however you phrase them. What time in New York now, NY time, and current time in Sydney all read your own clock, correct wherever you are.

Days until any date works, not just named holidays. Calciq reads the actual date, so days until July 4 and days until 12/25 both compute.

Geometry computes on your device with correct units. Area, perimeter, volume, and surface area across rectangles, triangles, circles, spheres, cylinders, and cones, with a length times length answer shown in m².

Time zone answers now flag a day change, so 7:00 AM (+1 day) reads unambiguously.

Scientific and SI conversions widened considerably, covering current, charge, moles, candela, and far more metric prefixes. Number conversion works across any base from 2 to 36.

2.2.2 June 2026

Far more units convert offline, including pressure, energy, power, force, frequency, data rate, fuel economy, and torque. Even 5 parsecs to furlongs computes on your device.

More math answers locally too. Hyperbolic functions, absolute value, floor, ceiling, rounding, gcd, lcm, and list statistics, in symbols or plain English.

Developers gained octal conversion, bit shifts, and bitwise NOT alongside the existing hex and binary support.

Mortgage affordability questions work again, answering a clarifying question keeps units on the result, and crypto conversions give a clear message rather than an error.

2.2.1 June 2026

A long list of math fixes. Logarithms with an explicit base, very large powers shown as a magnitude, negative exponents following standard convention, and thousands separators and currency symbols inside expressions.

Follow-ups got much better. Changing one value now recomputes the whole projection, asking for a new calculation by name starts fresh, and explain that walks through the real formula with your actual numbers.

Multi-step questions like split 100 three ways and add 10% are now answered end to end instead of half computed.

In the terminal, Esc clears the line rather than quitting, and your question stays visible while an answer is on its way.

2.2.0 June 2026

Open-ended finance arrived. Ask how much house you can afford at a monthly payment, rate, and term, or what the most you can borrow is, and Calciq asks for anything missing in a single question before computing.

2.1.0 June 2026

Live currency conversion. Ask 100 usd in eur and get a real rate as of today, still working offline from the last known rate with a note when it's stale.

More instant local answers, including natural language trigonometry, logarithms, bitwise operations, age from a birthdate, and time zone conversion.

When a question is genuinely ambiguous, Calciq asks one focused question instead of quietly guessing.

2.0.5 June 2026

Send Feedback and Report Incorrect Result arrived in Settings, the second prefilled with what you typed and what you saw.

A global hotkey on Mac, ⌃⌥K, opens the calculator from anywhere.

Multi-part questions now list every detail the assistant needs rather than trailing off.

In the terminal, you can edit anywhere in the line rather than only at the end.

2.0.4 June 2026

Follow-up answers became reliable. Asking whether a figure was a total or per person now answers correctly instead of occasionally redoing the math wrong, and a missing value is asked for rather than guessed.

2.0.3 June 2026

Repeating an AI question within your last seven days reuses the saved answer across every surface, so it costs nothing from your allowance.

Several correctness fixes. Negative temperature conversions, splitting by zero, compounding frequency on APY, and trigonometry at boundary angles, where sin(180°) now reads 0 rather than floating point noise.

The terminal gained a splash screen, a :color command, and Ctrl+Y to copy the latest result.

2.0.1 June 2026

Clear History arrived in Settings on both platforms and as a command in the terminal. Clearing is local and never touches your monthly AI allowance.

An accent color picker came to iPhone, matching the Mac, and the palette swapped a near-identical teal for violet.

Answering an AI clarifying question now continues the conversation rather than dead ending.

1.0.0 May 2026

First release.

The same plain English calculator on iPhone, Mac, and in the terminal. Type a question and get an answer, with no modes and no buttons, spanning everyday math, finance, developer conversions, and scientific functions.

Each answer feeds the next, so a running total builds as you go. For anything the built-in rules don't cover, AI steps in.
