Notepad Calculator vs Network & System Admin Toolkit

Notepad Calculator is a smart calculator disguised as a notepad. Instead of juggling a calculator app and a notes app, just write what you're thinking — every line is calculated instantly, right next to your words. Write math the way you think Type expressions in plain language and get answers on the same line: 500 + 200 * 3 → solved as you type, no equals button needed 10 km in miles, 5 feet 6 inches + 8 in today + 3 weeks, Jan 1 2025 to Mar 1 2025 tax = 15% then reuse price + tax anywhere below 8%, VAT, tip, subtotals and totals with #tag aggregation Every answer becomes a variable you can reference later, so multi-step calculations stay readable. Powerful, all offline A fast local engine handles a huge range of math with no internet, accounts, or AI required: Functions: sqrt, sin, cos, tan, log, ln, exp, abs, round, max, min, pow, and more Constants: pi, tau, phi, e Units & conversions: length, weight, volume, time, speed, temperature, electrical, and custom units Currency conversion with offline-cached exchange rates and a live "Update Rates" refresh Statistics, percentages, bases & bitwise (hex/binary/octal), trig in degrees or radians Chinese large-number support (万 / 亿) and spelled-out numbers (million, billion) Make it yours Definition Sheet — define global variables, your own units (1 box = 12 items), and custom functions (f(x) = x * 2) that apply to every document Organize work into folders, pin, archive, and search across all notes Headers (# Title), dividers (---), and tag totals keep long sheets tidy Tint the results column, align answers, and adjust line spacing to taste Export any sheet to Markdown or CSV Built for Mac Menubar Quick Calc — pop open an instant calculator from the status bar without leaving your work iCloud sync — your notes and calculations follow you to iPhone and iPad Native Mac storage, autosave, and a clean three-pane layout (sidebar · editor · live results) Smart autocomplete for units, currencies, functions, and variables 10 interface languages with live switching Whether you're estimating a project budget, converting recipes, planning a trip, or just splitting a bill, Notepad Calculator turns your notes into a living spreadsheet — without the spreadsheet.
