TabCalc - Calculator

Never go back to a calculator that erases your work. TabCalc keeps a separate tape in every tab, so calculations run side by side. Basic and scientific, one tap apart.

TabCalc is a calculator that keeps a separate calculation tape in every tab. Run several calculations at once: estimates and household budgets, materials and labor. Switch between them freely.

Features

• Each tab keeps its own expression, tape, and last answer. Switching tabs never clears your work (up to 10 tabs)
• Your calculations stay on screen like a paper tape, stacked in order so you can look back at any time
• Tap any entry to insert that answer into the current expression. Long press to copy
• Switch between basic and scientific with one tap. The tape stays the same within a tab
• Scientific mode covers trigonometry, logarithms, exponentials, square and cube roots, powers, factorial, reciprocal, pi, e, and EXP. The 2nd key switches to inverse trigonometric functions and powers of ten
• Toggle between DEG and RAD
• Basic arithmetic is exact. 0.1 + 0.2 correctly shows 0.3
• Thousands separators, with scientific notation for very large or very small numbers
• Tabs, tape, and the expression you were typing are all restored when you reopen the app
• Light and dark mode, 24 theme colors, Japanese and English

Who it's for

• Anyone adding up several totals at once while shopping or budgeting
• Anyone splitting estimates or costs into separate line items at work
• Students and professionals who need a scientific calculator
