Bend Calculator vs BendSource

Sheet Metal Bend Calculator is a focused utility for press-brake and sheet-metal layout work. Calculate the values fabricators use every day: - Bend Allowance (BA) - Bend Deduction (BD) - Outside Setback (OSSB) - Flat Length - K-Factor - Single-bend and multi-bend parts The app makes angle and dimension conventions explicit. Choose bend angle or included angle, then calculate flat length from tangent-straight dimensions or outside mold-line dimensions without mixing assumptions. Built for practical shop calculations: - Decimal inch and metric units - Editable K-factor - K-factor solver from measured bend data - Material/tooling presets - Saved calculation history - Text share for quick checks - Pro CSV/PDF exports for shop summaries - iCloud sync with local fallback Free includes ads and practical limits. Pro removes ads and the daily calculation limit, and unlocks expanded history, presets, multi-bend parts, and export workflows. Pro is available two ways: a one-time purchase that is yours for good, or a weekly subscription that renews until you cancel. Both unlock exactly the same features. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled in your App Store account settings. Important: bend results depend on material, tooling, grain direction, bend method, and shop practice. Use this app as an engineering aid and verify results against your own shop data before production.

BendSource turns supported EMT layouts into tape-ready fractional marks while keeping the formula, bender value, rounding rule, and source visible. CALCULATE SUPPORTED EMT BENDS • Offset bends with spacing and shrink • 90° stub-ups and back-to-back 90s • 3-point saddles using sourced 45° and 60° center-angle methods TAPE-READY MARK SHEETS See numbered M1–Mn positions, bend references, spacing, and rounded inch fractions in one place. Choose the rounding increment used for the displayed marks. CHECK THE METHOD Open Formula Mode to review the substituted values, unrounded result, preset provenance, manufacturer document, cited pages, and applicability notes. USE YOUR BENDER VALUE For supported 90° methods, you can save a take-up value read from your own bender or manual. User-entered values remain clearly labeled Check Bender and are never presented as manufacturer presets. PRIVATE AND OFFLINE Core calculations, saved Mark Sheets, and user presets stay on your device. BendSource has no account, ads, analytics SDK, or subscription. SCOPE Version 1 supports 1/2-inch, 3/4-inch, and 1-inch EMT for the bend methods shown in the app. A calculated result confirms the math and selected inputs; it does not claim a physical bend, jobsite conditions, or a specific bender has been field verified. Offset calculations and the source catalog are free. One Lifetime Unlock enables the other supported calculators, saved Mark Sheets, and user presets.
