## What is TabCalc?

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
