Velocity
Maintenance developmentperformancemonetizationplatform expansionShow more...
Development momentum is classified as maintenance, with the latest release arriving 6 days ago after a significant gap in cross-platform parity. While the Android version received updates for newer OS compatibility and billing, the iOS platform has remained stagnant for over 1,500 days. The current development trend is focused on technical stability and platform-specific feature maintenance rather than consistent cross-platform iteration. The app is not currently utilizing a live-ops model to drive engagement.

Key takeaways for Roll Calculator
Where is it heading?
The industrial utility market is consolidating around tools that guarantee measurement precision. Roll Calculator remains exposed: unless the calculation engine is audited and fixed, the app will continue to lose professional users to more reliable alternatives, regardless of platform compatibility updates.
- Calculation engine inaccuracies (thickness and depth variables) erode professional trust → users abandon the tool for manual estimation methods.
- Maintenance-only update cadence (Android 16 support) fails to address the critical calculation engine complaints reported by users.
The SWOT
- Specialized measurement algorithms for rolled materials
- Implement user-requested custom material template saving
