About this app

ABCalc is an advanced programmable calculator for people who need more than a basic keypad calculator. It lets you enter, edit, review, and reuse complex calculations as clear text, while still giving you fast access to arithmetic, scientific functions, statistics, programming-oriented operations, unit conversions, variables, history, and custom functions.

Instead of forcing every calculation through a small sequence of buttons, ABCalc gives you a regular text editor for expressions. Type a formula, adjust it, copy it, paste it, correct one part of it, or keep several related calculations together. This makes ABCalc useful for longer expressions and custom functions, repeated work, technical notes, study tasks, and any situation where you want to see exactly what you calculated.

Results can be displayed in multiple formats at the same time. This helps you understand the same value from different perspectives and avoid reconfiguring the calculator just to check another representation.

Your calculation history persists across sessions, so previous work remains available after you close and reopen the app. Return to earlier expressions, reuse them, modify them, or keep a record of what you calculated. This is useful when solving related problems, comparing alternatives, or returning to a calculation after an interruption.

ABCalc includes an unlimited number of memory cells in the form of variables. Store intermediate values, name important quantities, and build more readable expressions. Variables make calculations easier to organize, especially when the same value is used more than once or when a formula depends on several named inputs.

The app includes over 100 built-in functions for statistics, science, programming, and everyday calculations. Use the available function set for mathematical work, data-oriented tasks, engineering-style calculations, programmer-friendly operations, and general problem solving without having to recreate every formula from scratch.

ABCalc includes unit conversion with over 100 units of measurement. Convert values directly inside your calculation workflow instead of switching to a separate tool. This is helpful for school, engineering, travel, cooking, shopping, technical documentation, and other situations where different unit systems meet.

ABCalc is suitable for students, engineers, developers, analysts, teachers, and anyone who regularly works with formulas. Students can keep homework calculations visible and editable. Developers can benefit from programming-oriented functions and clear variable-based expressions. Technical users can combine unit conversions, functions, and history to keep complex work understandable.

Key features:

• Enter and edit complex expressions using a regular text editor
• View results in multiple useful formats
• Keep a persistent calculation history across sessions
• Use unlimited variables as memory cells
• Access over 100 built-in functions
• Convert between over 100 units of measurement

ABCalc combines the clarity of text-based calculation with the convenience of a modern calculator app. It is powerful enough for advanced expressions, flexible enough for custom functions, and practical enough for everyday use.

The ABCalc Plus variant additionally includes over 30 light and dark themes and support for custom function libraries.
