Triangle Calculator is a specialized geometry utility for students and engineers that computes right-angle triangle properties on iOS.
The App DNA
What makes this app unique?
It removes the cognitive friction of manual geometric calculation by providing high-precision results and visual proportional feedback.
For Students, engineers, and professionals requiring quick, high-precision right-angle triangle calculations.
What does it look like?
Key features
Calculates lengths, angles, area, and perimeter using two known values.
Draws a triangle based on calculated values, with alerts when proportions are too small for accurate visual representation.
Performs all math using 64-bit double precision, providing up to 15 significant digits.
How much does it cost?
Triangle Calculator is distributed as a free utility with no visible monetization or in-app purchase gates.

Key takeaways for Triangle Calculator
Where is it heading?
The math-utility market is consolidating around tools that offer cross-platform cloud sync and broader geometric support. Triangle Calculator remains a stable, specialized tool, but its lack of active development limits its growth potential against more agile competitors.
- The 1908-day update gap indicates a maintenance-only posture, which limits the app's ability to compete with modern, cloud-integrated math utilities.
The SWOT
- 64-bit double-precision engine provides 15 significant digits
- Proportional visualization alerts prevent geometric modeling errors
- Add support for non-right-angle triangles to expand audience
- Implement history export for engineering workflows
