LiveCalc – Notizrechner
Live calculations, clearly.
Free
liveCalc brings notes and calculations together in a focused native editor. Write formulas the way you think about them and see each result immediately beside the matching line.
VARIABLES AND DEPENDENCIES
Define a value once and reuse it in later calculations. liveCalc highlights related variables and shows what each result depends on.
UNITS AND CONVERSIONS
Convert metric, US customary and Imperial measures, electrical quantities, energy, data rates, and more. Explore the searchable unit reference and example notebooks.
NUMBERS AND EXCHANGE RATES
Choose decimal and thousands separators with a preview and presets. Request dated ECB reference rates, use saved rates offline, and preserve them as a fixed formula with its source in your notebook.
FUNCTIONS AND CHARTS
Define functions directly in your notebook and explore their shape in the built-in chart.
MULTIPLE NUMBER BASES
Work with binary, octal, decimal, and hexadecimal values and format results for the task at hand.
ORGANIZE AND EXPORT NOTEBOOKS
Start from a template, organize notebooks into groups, and search titles or calculations. Preview multiple files before importing. Export editable notebooks, text with results, or colored images with six themes and three layouts. Results share a fixed column, with optional line numbers. Black-and-white export and native printing are also available.
A NATIVE, PRIVATE WORKSPACE
Calculations and documents are processed locally on your device. liveCalc includes no advertising, tracking, or analytics SDKs. Open and export notebook files or share them through the system share sheet.
liveCalc is designed for quick estimates, technical notes, learning, and any task where the calculation and its reasoning belong together.
