semper Measures Strain with a Phone

Why it surfaced

semper runs digital image correlation on the phone: photograph a painted random speckle pattern before and during loading, then inspect how each image window moved. It works offline-first and documents its limits plainly—the app does not perform scale calibration—while offering a manual, glossary, parameter reference, and early access for testers.

An Android tool that turns speckled photographs into full-field displacement and strain heatmaps for courses and research groups.
