About this app
Bend Allowance Calculator is an offline utility for sheet metal fabrication, repair work, and manual layout. Enter sheet thickness, inside radius, bend angle, K factor, and flange lengths to quickly calculate flat length, bend allowance, and bend deduction, then save common material and process templates. The app supports millimeter/inch switching, quick entry for common angles, reverse calculations, error alerts, local project records, and reusable templates. All data stays on your device. No account, no network access, and no user data collection.

- Developed length summary: support cumulative addition of multiple bend edge lengths
- Material templates: locally save common plate thicknesses, K-factors, and inner radius angles
- Unit switching: quick conversion between millimeters and inches
- Reverse calculation: estimate edge length or deduction value from target developed length
- Error alerts: prompt for abnormal angles, small radii, and missing parameters
- Local projects: save historical calculations and notes
- Convenient for rechecking
