TabCalc - Calculator with Tape

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 This app displays ads. A one-time in-app purchase removes them permanently. Every calculation feature is free. Privacy Policy: https://momokusafarm-pixel.github.io/tabcalc-privacy/
