Calculator completely free. Add-Ons (Table of Elements, OCR Number Scanner) as in-app purchase.

innovations and add-Ons:
1. "Picking": swipe left/right on a button and any two more numbers on the stack can be calculated on - complete freedom to play with your numbers!
2. "Flick" up/down and buttons activate the 2nd and 3rd calculator functions
3. Table of Elements with many element properties to copy to the stack. Colored heat maps to show relative property distributions
4. Infinte Stack (scrolling)
5. OCR technology to scan in numbers to the calculator stack
6. unique scroll-wheel to quickly calculate TIPs for restaurant bills
7. dedicated memory buttons (also with flick technology: just swipe and tap, and the number is saved)

The only app that combines the spirit of old calculators with new technology:
You will not believe how intuitive and natural this feels: its like RPN was made for touchscreen:
Being stuck to operating on two adjacent numbers is yesterday!

The interface is fluid and intuitive for bringing your thoughts together, put numbers on the stack - contemplate them - manipulate. We designed for fluid gestures and made the experience thoroughly modern.

Just enough scientific functions to be super useful - but not annoying.

Dedicated memory buttons.

Interactive Tutorial.

World's first calculator that can scan in numbers with the camera.

Beautiful periodic table with quick access to the reference data of elements - available for quick copy to the calculator. just rotate to landscape to bring it up. Big thanks to Mark Semadeni!

Clever design and intuitive activation make this app a pleasure to use.

Super

first calculator app with integrated periodic table. Ingenious for chemists and chemical laboratory assistants or for those who often calculate empirical formulas and to produce solutions for a wide variety of compounds. A must have in the laboratory

Mein Favorit

Sehr guter Rechner mit umgekehrter polnischer Notation mit guter Übersicht des Stacks und einigen handlichen Funktionen.

Es wurde viel Wert auf eine Gute Darstellung und ein Maximum an Funktion auf kleinem Raum gelegt. Gut finde ich auch, dass ich nur ein absolutes Minimun an „Clicks“ machen muss um mein Resultat zu erhalten.

Das i-Pünktchen für mich als Elektroingenieur ist natürlich das Parallel-rechnen von 2 Widerständen.

Ich kann die App nur weiterempfehlen!
