Hardness Master V 1.0.5 To meet the highest standards of heat treatment production lines and QC requirements, this update features an epic engine rebuild. We have not only drastically improved data accuracy but also delivered a tailor-made workflow upgrade for industrial practitioners! Integrated 0.1-Step Limit Database Say goodbye to rough estimates! We embedded high-density, 0.1-step practical physical test data directly into the App's core. Whether it's HRC, HV, HBW, or MPa, every decimal you input maps to the most precise industrial reference. New V8 Conversion Engine (0 Latency Experience) Introduced pre-built dictionary indexing and Binary Search algorithms. Instantly sync and convert all units the moment you type. Fully background-processed, completely eliminating stutters and blank screens for a silky-smooth feel. HV Smart Relay Bridge Technology Solved blind spots in cross-range conversions! When specific Rockwell hardness cannot directly map to low-strength MPa, the engine auto-activates the HV Vickers relay for dual conversion, ensuring a fully connected numerical network across 15 units with near-perfect hit rates. Production Line Exclusive: Keep Awake Mode We heard our field engineers! Enable Production Line Mode in Settings, and your screen will stay awake while the App runs. Wearing gloves or having oily hands? Your phone remains your most reliable industrial dashboard without needing constant unlocking. Unlock Ad-Free Pro Version Measurement requires absolute focus. We launched a permanent buy-out Pro version. Upgrade with one tap to permanently remove all intrusive ads, bringing you the purest, most efficient measurement space. Other UX Optimizations: Redesigned numeric keypad logic, supporting intuitive manual backspace deletion. Cursor always aligns right for better ergonomics. Enhanced floating-point tolerance, ensuring precise docking for all extreme boundary values. Thank you for using Hardness Master! If you love this flagship upgrade, please leave us a 5-star review. It's our biggest motivation for continuous development!
