Screw-Designer Basic
Screw-Designer Basic is a mobile calculation utility for mechanical engineers to perform VDI 2230-compliant screw joint pre-design.
The App DNA
What makes this app unique?
The app removes the need for desktop-bound software during initial fastening system design, allowing engineers to validate joint reliability in the field.
For Mechanical engineers and fastening system designers requiring mobile pre-design calculations.
What does it look like?
Key features
Calculates tightening and loading based on VDI 2230 guidelines, serving as a brand authority mechanism.
Applies factor-based preload loss calculations for high-reliability engineering.
Generates visual diagrams for tightening and force elongation.
How much does it cost?
The app operates as a free, limited-feature entry point to drive awareness and sales for the developer's professional software package.
Velocity
Dormant developmentopaqueShow more...
With the latest release occurring 374 days ago, the app falls into the zombie category. Development has been stagnant for over a year, with no evidence of recent feature updates or operational activity. The platform-specific history shows a significant disparity, with the iOS version remaining untouched for over 4,200 days. There is no current development momentum to report.

Key takeaways for Screw-Designer Basic
Where is it heading?
The engineering utility market is shifting toward more flexible, user-defined calculation tools, yet Screw-Designer Basic remains anchored to a static VDI 2230 implementation. The app's current trajectory is stable but limited, as the lack of active development prevents it from capturing the non-standard hardware segment that currently drives user frustration.
- The 374-day update gap indicates a maintenance-only posture, which prevents the app from addressing evolving user requirements for custom hardware inputs.
- High sentiment scores among existing users suggest the current feature set provides consistent value for standard hardware assembly tasks.
The SWOT
- VDI 2230 compliance establishes technical authority
- Preload relaxation factor addresses high-reliability design needs
- Manual input fields would capture non-standard hardware users
Next best moves
Ship manual screw dimension input because users cite this as the top missing feature → increase user satisfaction
The counter-intuitive read
The app's dormancy is a feature, not a bug…
Read the full takeBottom line
The lack of development activity suggests Screw-Designer Basic is a legacy lead-generation tool, and adding manual input fields would unlock the non-standard hardware segment currently driving negative sentiment.
