Description

InstruCal turns an iPhone into a force calibration station. Connect a Morehouse HADI reference indicator through a small ethernet adapter and point the camera at the display of the device you're calibrating, and capture each point with one tap: the app records the reference force and the displayed value side by side and calculates the error at every point. • Live reference force from the HADI, converted with your load cell's certificate coefficients • On-device camera reading of the customer's display (Apple Vision or PaddleOCR) • 10- or 20-point runs with automatic targets from the device's capacity, including return to zero • Two runs side by side with % error, compression or tension, lbf/kgf/N/kN/klbf/tonf • Import Morehouse calibration certificates (PDF) with automatic coefficient checks • Export results to CSV for your calibration report • No account, no data collection — everything stays on your iPhone

What's New

Version 1.1 2026-11-06
New in 1.1 • Dead-weight points: mark any point as a weight point and the app works out the force from the weights and your local gravity, so no HADI is needed...New in 1.1 • Dead-weight points: mark any point as a weight point and the app works out the force from the weights and your local gravity, so no HADI is needed for those rows. Gravity comes from your location automatically, or you can enter your own value. • Capture now compares each display reading with the HADI at the same moment and keeps the median pair, and it always captures. • Calibration CSV in a fixed layout, saved to the Files app. Save As… lets you name copies like As Found and As Left. • Edit or enter any point by hand. • Overload warning above 105% of capacity. • Sign options for displays that read tension as negative, plus a Flip sign switch. • Bluetooth shutter remotes and the volume buttons can press Capture. • Table and number display improvements.
