## What is BVCalc?

Calculate with confidence. BVCalc combines live-updating algebraic entry with an RPN stack that shows the full expression behind every value. Reuse past work with a tap, switch modes anytime, and audit every step.

Why BVCalc
• Live result as you type, so no need for a  “=” key
• Reuse expressions, not just values
• Shared tape/stack with readable infix history
• Switch between Algebraic ↔ RPN mid-calculation
• Touch-friendly stack gestures (tap to swap/roll)
• Basic & Scientific keyboards + external keyboard support
• Long-press to edit any past step; copy/paste everywhere
• Color-coded parentheses, themes, high-contrast mode
• Memory for reusable snippets
• No ads

BVCalc makes partial-step workflows fast and reliable: what you see is the math you actually entered.
