Installation & Usage Instructions
Getting CalcService up and running is straightforward, regardless of your operating system. Windows users can download the installer from the official website, run the .exe file, and follow the on‑screen wizard. The installer automatically creates a desktop shortcut and adds CalcService to the system tray for quick access.
macOS users should download the .dmg package, drag the CalcService icon into the Applications folder, and launch it from Launchpad. For Android, open the Google Play Store, search for “CalcService,” tap “Install,” and grant the necessary permissions to overlay on other apps. iOS users can find the app in the App Store, install it with a single tap, and enable “Keyboard Extension” in Settings to use the calculator directly within any text field.
Once installed, activation is as simple as typing an expression within square brackets, for example [12 + 7 × 3]. Press the configured trigger (default: Ctrl + Enter on desktop, a floating “=“ button on mobile) and the bracketed text is instantly replaced with the computed result, e.g., 33. The app also offers a small overlay window that can be summoned with Alt + C (Windows) or a swipe gesture (mobile) for quick one‑off calculations. Users can customize the trigger keys, decimal precision, and display format from the Settings menu, which is accessible via the system tray icon or the app’s main screen. All preferences are saved locally, ensuring a consistent experience each time you launch CalcService.
For power users, CalcService includes a “History” panel that logs the last 50 calculations, allowing you to revisit and reuse previous results. The history can be exported as a CSV file for record‑keeping or imported back into the app if needed. Additionally, the “Script Mode” lets you write multiple lines of calculations separated by semicolons, perfect for batch processing simple financial models or statistical formulas without leaving your text editor.
