About

KatKalk

Features
Read full description

KatKalk is a configurable position calculator designed for the fast entry of many individual values. Unlike a conventional calculator, KatKalk keeps every entered position visible. This makes calculations easy to follow, verify and correct—even during fast-paced work. KEY FEATURES • Add, subtract, multiply, divide and calculate percentages • Keep every entered position clearly visible • Add short notes to individual positions • Save and reopen multiple sessions locally • Copy or remove the latest position • Choose from ready-made calculator profiles • Customize the keypad, screen layout and visible controls • Export sessions as readable HTML reports • Print reports directly from a compatible browser • Export and import KatKalk session files • Use the core calculator without an internet connection • Follow shared sessions in read-only viewer mode BUILT FOR PRACTICAL WORK KatKalk is especially useful when many prices, products or other individual values must be entered quickly while the complete calculation remains traceable. Every accepted value becomes a separate position. You can review the complete list, identify corrections and keep short product names or other information next to the corresponding value. FLEXIBLE CALCULATOR PROFILES Choose a simple profile for everyday calculations or adapt KatKalk to your own workflow. Depending on the selected profile, you can customize: • The calculator keypad and its arrangement • Visible buttons and quick-access actions • Notes and audio controls • Position numbers and counters • The total and cumulative totals • Font sizes and screen areas • Calculation and percentage rules Profiles for simple calculations, notes, recordings, advanced controls and classic calculator operation are included. SESSIONS AND REPORTS Save different calculations as separate sessions and reopen them later. KatKalk keeps the individual positions and notes together with the session. Create a readable HTML report for browsers, smartphones and printing. You can also export a KatKalk session file and import it again to continue working with the calculation. LOCAL BY DEFAULT Calculations, notes and saved sessions remain on your device. KatKalk’s core calculator works fully offline. Optional online functions are clearly separated from local calculation. Shared sessions can be followed in read-only viewer mode without allowing viewers to alter the master calculation. KatKalk is not intended to replace accounting, invoicing or financial advisory software. It is a practical tool for fast, transparent and configurable position calculations.
