Circle Calculator - Geometry
By AHMET DEMIR
Circle Calculator - Geometry is a specialized utility for engineers and metalworkers that provides geometric calculations and offline technical data on iOS and Android.
The App DNA
What makes this app unique?
The app removes the need for internet connectivity during field work, displacing manual reference charts and general-purpose calculators with a persistent, workshop-ready interface.
For Engineers, metalworkers, and technical students requiring precise geometric calculations and offline workshop data.
What does it look like?
Key features
Generates PDF, CSV, and DXF files for bolt circle coordinates and pipe templates.
Access to DN/NPS pipe dimensions and weights without an active internet connection.
Visual representation of measurements that updates in real-time as inputs change.
How much does it cost?
The freemium model gates professional export formats and expanded project capacity behind a Pro tier, while keeping core geometry tools free to drive ad-supported usage.
Velocity
Maintenance developmentperformanceShow more...
The app maintains a maintenance-tier velocity, with only one release recorded in the analyzed window. The latest release focused exclusively on infrastructure and stability, indicating a lack of new feature development. With the most recent update occurring 66 days ago, the development cycle remains infrequent and focused on technical upkeep rather than product expansion.

Key takeaways for Circle Calculator - Geometry
Where is it heading?
The market for specialized engineering utilities is consolidating around tools that offer seamless integration with professional CAD workflows. Circle Calculator - Geometry remains advantaged by its offline-first design, but the lack of cloud-sync will eventually create a churn risk as professional users shift toward multi-device project management.
- The maintenance-only release cadence indicates a stable, low-overhead product strategy that prioritizes tool reliability over rapid feature expansion.
- High user satisfaction regarding the ad-free, persistent-display interface suggests the core utility is well-aligned with professional sketching and design workflows.
The SWOT
- Offline-ready pipe schedule database reduces connectivity dependency for field workers
- Persistent measurement display during interaction sustains session utility for design tasks
- Professional export formats (DXF/CSV) create a direct conversion lever for CAD-ready workflows
- Expansion into localized metal-stock weight standards could capture untapped professional segments
- Integration of direct CAD-software import plugins would deepen the Pro-tier value proposition
