Flexible Calculator Pro

Flexible Calculator Plus is a full-featured tape calculator that shows every step of your work — so you can always check what you calculated and why.

TAPE VIEW: SEE EVERY STEP
Unlike a standard calculator that only shows the current number, Flexible Calculator Plus displays a scrollable tape of your entire calculation. Review, verify, and catch mistakes before they matter.

COMPLETE HISTORY
Your calculation history is saved automatically. Scroll back through past sessions, copy any result, or pick up exactly where you left off.

MEMORY FUNCTIONS
Store and recall values with M+, M−, MR, and MC. Essential for multi-step calculations where you need to hold an intermediate result.

BUILT-IN UNIT CONVERTER
Switch to the unit converter to convert lengths, weights, temperatures, and more — all without leaving the app.

CLEAN, FOCUSED INTERFACE
Three tabs: the live tape calculator, your saved sessions, and the unit converter. No clutter, no unnecessary features.

WORKS OFFLINE
No internet needed. No account, no ads, no data collection. Just a clean, reliable calculator.
