Omacus updates

v0.2.11 — See every update in one place

2026-10-23T10:54:10Z

The updates page lists each version in plain words, newest first. What's new in the app opens the same page.

v0.2.10 — A cleaner, calmer look

2026-10-23T10:06:55Z

The app and the website share one quiet look, in light and dark. Type, spacing, and colour come from the same choices, so a screen matches the site.

Settings, About, and dialogs use the same frames and buttons

v0.2.9 — Edit names like any other text

2026-10-23T07:28:25Z

Renaming a value, a folder, or a handle is a normal text field: you can select, paste, and use the arrow keys. Hovering a value such as @trip.total shows one card, with the amount and the page it comes from.

Press F2, or choose Rename. Enter keeps the name, and Esc puts it back

v0.2.8 — Lock pages and folders with a password

2026-10-23T07:09:35Z

A page or a folder stays locked until you type the password. Without it, the notes and the numbers cannot be read.

Lock one page, or a whole folder, from its menu

v0.2.7 — Use a number from another page

2026-10-23T06:11:35Z

Type @trip.total to use a value from Trip Budget on the page you are writing. Change the number there, and every page that uses it follows.

Typing @ lists your pages, then the names on the one you pick
Renaming a name, or the page's handle, updates every use
A missing page stays a quiet hint

v0.2.6 — Use your pages from the terminal

2026-10-23T05:49:43Z

Calculate a line, or a whole page, from the command line. You can list, create, and export pages, and tools such as Cursor and Claude can do the same.

Export a page as notes, or as a PDF

v0.2.5 — Organize pages into folders

2026-10-23T05:21:35Z

Drag a page into a folder in the sidebar, and keep a long list in order. Folders open and close, and a new folder starts from the sidebar.

v0.2.4 — Rename a name everywhere it appears

2026-10-23T04:24:59Z

Rename a value and every line that uses it updates, in one undo. Enter keeps the name, and Esc cancels.

Press F2, use the right-click menu, or choose Rename when you hover
On a phone, long-press the name
A name that is already used on the page is refused

v0.2.3 — Answers update as you type on a phone

2026-10-23T02:35:16Z

A line such as groceries = 100 shows 100 right away, and groceries * 2 shows 200. Lines below the one you edit stay current.

A dash or a curly quote still calculates, so 100 – 20 is 80

v0.2.2 — Preview and PDF stay in step with the page

2026-10-23T01:14:47Z

Scrolling a long page scrolls the preview too. The PDF keeps your lines, blank lines, and comments, and uses the page title as its file name.

Settings opens as a tab beside About
Check for updates can run again after it finishes

v0.2.1 — Clearer printing, and Settings from the sidebar

2026-10-22T23:45:35Z

Print and Export PDF set the page like a short document, with margins and headings, and a line is not split across a page. The gear at the bottom of the sidebar opens Settings.

A value you hover stays on one line, inside the window
An answer on the line keeps its brackets, for example [ $48 ]

v0.2.0 — Preview a page, and see a value when you hover

2026-10-22T19:32:06Z

Ctrl+P shows the page as notes, with each answer beside its line. Hover a name, or a number such as 1.5k, to see its value, and click an answer to copy it.

The web app opens when you are offline, and says so if exchange rates may be old
Settings chooses the theme, where answers sit, and whether to check for updates
A list or a heading can hold a calculation, so - hotel = 3 nights * $180 names hotel
The sidebar, the docs, and the app say page

v0.1.29 — Sidebar icons line up

2026-10-22T15:49:02Z

The new-page button, the sidebar button, and help sit on one line with the rows beside them.

v0.1.28 — Open a deleted page before restoring it

2026-10-20T05:09:48Z

A page in Recently deleted can be opened so you can read it, then restored. A long name stays on one row.

v0.1.27 — The page list keeps your place

2026-10-20T02:03:50Z

Moving through the page list with the keyboard no longer sends focus somewhere else.

v0.1.26 — Sum a few amounts, and bring a page back

2026-10-19T23:07:10Z

sum(), avg(), min(), and max() take a list of amounts, including units and currencies. Deleting a page asks first, and Recently deleted can bring it back.

The page list is Ctrl+J (Cmd+J on a Mac)
An unknown name stays a quiet hint, once you pause
A long page opens reliably on a Mac

v0.1.25 — Millions and billions on an amount

2026-10-19T14:25:18Z

After a currency symbol, m and mm mean million, and b means billion. $2m is two million dollars, not a length.

v0.1.24 — Plan runway and a round

2026-10-19T13:13:42Z

Divide the cash you have by monthly spend to see how many months you can keep going. Write a round as an amount at a valuation to see the stake you give up.

v0.1.23 — Labels stay words

2026-10-19T12:55:23Z

A label in front of an amount, such as Groceries $80, stays a label. On a phone, the page stays still while you type, and the page list does not jump.

Omacus can be installed on a Mac with Homebrew
A rate such as $85/hour, or a percentage, no longer breaks the total beside it
After a currency symbol, b means billions

v0.1.22 — Percentages follow the order you wrote

2026-10-19T04:52:43Z

100 + 10% * 2 is 120. The percentage is applied in the same order as the rest of the line.

v0.1.21 — Totals that work inside a line

2026-10-19T01:02:36Z

total * 1.08 and total in EUR use the total of the block above, not only a line that says total by itself. Dollars and plain numbers in that total add together.

A line that is only a unit name, such as kg, shows nothing
A name you defined as total still wins over the block total

v0.1.20 — Behind-the-scenes improvements

2026-10-19T00:24:40Z

Nothing you see in the app changed.

v0.1.19 — Windows opens on more computers

2026-10-18T22:56:45Z

Omacus starts on a Windows PC that does not have a newer graphics driver. The first line gets the same time to finish as any other line.

v0.1.18 — Install on Windows in one click

2026-10-18T19:50:14Z

The Windows setup installs Omacus for you, with no admin prompt, and adds it to Start. On a Mac, the download opens to a window with the app and an Applications folder.

Or install from a terminal with one line, on Windows or anywhere else

v0.1.17 — Answers appear as they're worked out

2026-10-18T17:19:16Z

You see each line's answer as it finishes, instead of waiting for the whole page. Copying an answer no longer freezes or lands late, and an impossible date says so.

v0.1.16 — Clearer rounding, dates, and large numbers

2026-10-18T16:48:09Z

$1.005 rounds to $1.01. 1.000,50 reads as one thousand and a half, 1 lakh is 100,000, and a date on its own is that date.

today + 3 weeks stays on the right day when the clocks change
I spent $40 stays $40 even when I is also a name on the page
$-5 is minus five dollars

v0.1.15 — A long page stays quick

2026-10-17T22:12:07Z

Editing the end of a long page recalculates that line, not every line above it. The window does not wait on the math.

Each line gets the same time to finish, wherever it sits on the page

v0.1.14 — Percentages, money, and dates, more carefully

2026-10-17T21:48:07Z

10% off 20% off $100 is $72. C$ and A$ read as their own currencies, and Jan 31 + 1 month stays on the calendar.

Halves round on the exact digits: $1.005 is $1.01
10% * 200 is 20, not 2,000%

v0.1.13 — The window stays responsive

2026-10-17T20:59:21Z

A line that would take too long stops, instead of freezing the window. When a line has no answer, it can say why, quietly, in the answer's place.

$100 - 10% - 10% is $81
Tickets 2 x $14 is $28
A plain number added to an amount keeps the currency, so rent + 5 stays in dollars

v0.1.12 — Answers sit on the line, including on a phone

2026-10-17T20:37:00Z

Each answer sits at the end of its line, and moves below the line when there is no room. A phone no longer squeezes every line into half the screen.

On a phone, Share and Private live in the page menu

v0.1.11 — Try a page on the homepage

2026-10-17T13:08:08Z

The homepage can swap the demo for the real editor, on the page that was playing, without saving anything. A privacy page says what stays on your computer.

Share, and the page menu, sit above the page

v0.1.10 — Share a page with a link

2026-10-17T07:24:38Z

Share link copies a link that opens the page in the browser, or back in the app. The page is inside the link, so it is not sent to a server.

The web app keeps pages in this browser, and can open when you are offline
You can install it on your home screen

v0.1.9 — Tips, splits, and how long a download takes

2026-10-17T06:28:10Z

18% tip on $62, $84 split 3 ways, and 4 GB at 100 Mbps each get an answer. You can count days until a date, convert 16px in rem, and turn a colour such as #ff8800 into RGB, with a swatch.

Copy a page as a Markdown table
One download page covers every platform

v0.1.8 — A smaller download on a Mac

2026-10-17T05:46:23Z

There is a download for Apple silicon and one for Intel, so each file is about half the size. Two windows stay in step, and one does not overwrite the other.

v0.1.7 — Update checks through the day

2026-10-17T04:58:26Z

Omacus looks for a new version when it starts, and again every few hours while it stays open, instead of only once a day.

v0.1.6 — Undo a deleted page, and fewer wrong answers

2026-10-17T03:27:06Z

Deleting a page can be undone, and a failed save tells you instead of failing quietly. An amount in a label, such as Groceries $40, stays the amount you wrote.

half of 50 is 25, and 50 percent off 80 is 40
I spent $40 is $40, and $4 a day is four dollars a day
An update checks the download before it installs

v0.1.5 — Copy a page with its answers

2026-10-16T23:31:03Z

Copy with answers places each result after its line, ready to paste. You can jump to a page by its name, or by something written on it.

in 90 minutes, 3 hours from now in Tokyo, and 3pm + 45 min count from now
Exchange rates and the update check refresh while Omacus stays open

v0.1.4 — Update in one click

2026-10-16T22:51:28Z

On Windows, Update now replaces the app where it is and restarts. On a Mac, the update replaces Omacus where it already lives, instead of adding a second copy. Links in About open in the browser.

Help has its own window, and the version sits at the bottom of the sidebar

v0.1.3 — Omacus tells you when a new version is out

2026-10-16T22:25:21Z

A note at the bottom of the sidebar appears when a newer version is published. Update now installs it and offers to restart. Your pages and settings stay.

Turn the check off in settings
omacus --version prints the app's version

v0.1.2 — Imperial measures, and a time on a date

2026-10-16T21:46:08Z

2 imperial pints in ml converts UK pints, and CHF 300 works the same as 300 CHF. 3pm PST on Dec 1 in London uses the right offset for that date.

A date can be Dec 1, 1 December 2026, tomorrow, or next Monday
Words that only start like a day, such as Sunset, stay labels

v0.1.1 — Percentages and units that come out right

2026-10-16T21:02:42Z

6 is what % of 120 is 5%, and $100 - 20% takes the percentage off the amount. 60 km / 2 hours is a speed, and the units stay on the answer.

Two-word units such as nautical mile, fl oz, and sq ft
A block total can be saved with subtotal = total
The website, with docs and a download for each platform
The Mac installer puts Omacus in Applications

v0.1.0 — A notepad for math

2026-10-16T17:03:18Z

Omacus keeps a whole page. Every line keeps its answer, you can name a value and reuse it, and changing a line updates what follows. Pages are saved as you type, on Linux, macOS, and Windows.

Units, percentages, currencies, and time zones, written the way you would say them
The Omarchy installer asks before it adds a shortcut, and suggests Super+Ctrl+Alt+=
Two pages created a moment apart no longer overwrite each other
