About this app

ArithCalc is the tape calculator that works the way you think.

Instead of a single result that disappears, ArithCalc keeps your whole calculation visible — like a paper tape you can edit. Type line by line, add labels, and change any number at any time. Every total updates instantly.

WHY ARITHCALC
• See every figure — no more "did I type that right?"
• Fix any line in place — later results recalculate automatically
• Add a label or comment to any line (e.g. "Rent 650")
• Works like notes, calculates like a calculator

FEATURES
• Editable tape — correct any number, totals adjust instantly
• Labels & comments on each line
• Percentages (e.g. 650 + 10%, 500 − 30%)
• Multiple documents — keep separate tapes for work, budget, shopping
• Undo / Redo
• Memory keys (M+, M−, MR, MC)
• Light, Dark & System themes
• Adjustable decimals, thousand separators, font sizes
• Share your calculation or copy the grand total
• Works great on phones and tablets, portrait or landscape
• Fully offline — no account, no tracking

PERFECT FOR
Shopping lists, budgets, expense tracking, invoices, quick everyday math, and anyone who wants to check their work instead of trusting a single number.

ArithCalc is free. Type your calculation, keep it visible, edit anything — that's it.
