3D Interpolation
By Carlos Moura
3D Interpolation is a specialized utility for directional drilling calculations, serving engineers and students on iOS.
The App DNA
What makes this app unique?
The app removes the manual friction of calculating well-planning parameters like TVD and dog-leg severity by automating the Minimum Curvature method.
For Drilling engineers, technicians, drillers, and students of drilling engineering.
What does it look like?
Key features
Calculates TVD, coordinates, and dog-leg severity using the Minimum Curvature method.
Supports multiple units including degree/100ft and degree/100m to accommodate regional standards.
How much does it cost?
The $9.99 price point targets professionals seeking specialized tools without recurring subscription overhead.

Competitive landscape for 3D Interpolation
How's the Utilities market?
3D Interpolation operates as a niche utility in the Utilities category with a $9.99 price point. The lack of updates for over 25 months signals a maintenance-only posture that limits its competitive relevance against active engineering software.

Key takeaways for 3D Interpolation
Where is it heading?
The outlook for 3D Interpolation is declining due to critical calculation errors that remain unaddressed after two years of inactivity. Unless the developer resolves the azimuth logic, the app will continue to lose relevance to more reliable engineering tools.
- Mathematical errors in azimuth interpolation logic erode user trust, leading to unusable output data for professional drilling engineers.
- The 25-month release gap signals a lack of active investment, leaving the app vulnerable to spreadsheet-based alternatives.
The SWOT
- Configurable intensity units reduce switching costs for international project requirements
- Correcting azimuth logic would restore core utility for professional users
Next best moves
Audit and patch azimuth interpolation logic because users report inconsistent data output → restore core utility
