Calcutron: Smart Calculator

Calculator with live calculation, memory, a folder-based log, constants, a thoughtful interface, and flexible settings.

Calcutron is more than just a calculator — it is a convenient tool for everyday calculations and storing results.
It is designed for situations where you need more than a quick answer: you may want to save a calculation, come back to it later, and continue working without losing structure.

The app is designed not only to calculate, but to make numbers easier to work with overall. Memory, calculation history, and constants help you keep important calculations and values at hand and reuse them. The app does not limit the number of saved entries and values, while still remaining convenient even during extended work with calculations.

Calcutron offers extensive capabilities for calculating, storing, and organizing calculations:

• calculating as you type, with results updating in real time;
• an unlimited number of memory cells for short-term storage of calculation results;
• an unlimited number of history entries and folders for long-term storage of calculations themselves and their organization;
• many reference values, plus an unlimited number of personal values and categories for storing and organizing them conveniently;
• reusing saved values and calculations in new ones;
• color highlighting for important entries, as well as history folders and constant categories;
• search across history and constants;
• sorting of constant categories;
• comments for saved entries;
• gestures and quick actions for working with calculations faster and more conveniently.

This is especially useful when you need to return to saved calculations, quickly find the entries you need among them, and mark the important ones.

Additionally, the app offers optional premium features available through separate purchase:

• Pro (one-time purchase): additional themes, alternative app icons, and extended highlight options;
• Pro+ (auto-renewable subscription): backup and restore features, plus access to Pro features while the subscription is active.

Calcutron is a good fit for anyone who needs not just a calculator, but a more convenient and thoughtful way to work with everyday calculations.
