Notepad Calculator

Keep notes, calculations, and results on the same page. Notepad Calculator turns each page into a live calculation sheet. Write plain text, enter an expression, define a variable, or continue from the previous result. Answers appear inline so the reasoning stays visible beside the numbers. Use it for: • Personal budgets and expense breakdowns • Shopping totals, discounts, and tax estimates • Trip costs and bill splitting • Study notes and formula checks • Lists, averages, statistics, and unit conversions Features: • Multiple named pages for separate calculations • Instant results next to each expression • Variables such as price, tax, total, or any name you choose • Chained calculations using the previous result • More than 50 built-in math and statistics functions • Lists and the special above variable for nearby values • Searchable function reference with examples • Configurable decimal precision • Light and dark themes • JSON backup export and import • Local app storage with no account required • Calculation timeout and recovery tools for problematic expressions Notepad Calculator keeps the work readable: the notes explain the calculation, the expressions show the method, and the inline answers show the result. Your pages are stored in app storage on your device. Export a backup whenever you want a portable copy.
