Numerus is a calculation notebook: write expressions and see results beside each line. Keep the notes and reasoning that give your numbers context. CALCULATE AS YOU WRITE Use arithmetic, percentages, variables, functions, dates and unit conversions. Continue with previous results and summarize lists with aggregates. ORGANIZE YOUR THINKING Create pages, rename them, duplicate examples and find your work with search, tags and favorites. Explore the example library without leaving the app. SHARE AND KEEP YOUR WORK Export pages as PDF or editable .numerus files. Import pages and save a workspace backup. Page files can also be opened in Numerus desktop. WORK AT YOUR OWN PACE Local calculations work offline. Currency conversions use Frankfurter reference rates when connected and saved rates when available; they are not real-time market quotes. NO ACCOUNT REQUIRED There is no registration, advertising or in-app analytics. Pages are stored on your device, and you choose when to export them. System backups depend on your device settings. English and Spanish interface and examples, light and dark themes, and layouts that adapt to phones and tablets. BUILT TO USE AND SHARE Numerus began at Viento Digital as a tool for our own everyday calculations. We share it for free, without subscriptions or in-app purchases.
