FlexCalc is a flexible calculator designed for editable calculations, linked values, history, and instant result updates.

Unlike a standard calculator, FlexCalc lets you tap any number or result, edit it directly, and see related results update automatically. You can reuse results in new calculation lines, drag linked values between lines, and adjust formulas without retyping everything.

Key features:
- Edit any number in your calculation and instantly update the result.
- Reuse results as linked values in new calculation lines.
- Drag linked values to replace, insert, or adjust calculations faster.
- Move the cursor inside numbers for precise edits.
- Review and restore previous work with calculation history.
- Share calculations as text or an image.
- Customize the app with different themes and fonts.
