Purpose-Built
Materials-test reduction studio for engineering stress-strain, 0.2% offset yield, modulus fit, UTS, elongation, toughness, specimen correction, and repeat comparison.
One-time iPhone and iPad app
Ductilab
Stress-strain test reduction
Core Features

- Modulus, yield, UTS and toughness
- Specimen-photo evidence
Private by Design
No account, subscription, ads, tracking, third-party analytics, or developer-operated backend. Core features work offline, and your work stays on device unless you deliberately share or export it.
Use It Responsibly
Stress-strain calculations do not certify material performance. Confirm specimen geometry, machine calibration, test standard, units, and qualified engineering interpretation.
