This app visualizes the unit circle in an intuitive way, allowing users to enter angles in radians or degrees and instantly calculate all important trigonometric values. It supports sine, cosine, tangent, and related unit circle values, making it ideal for high school math, college trigonometry, pre-calculus, and calculus learning.

Every calculation is shown step by step, helping users understand not just the result, but also the calculation process behind it. The app includes animated angle visualization, so users can clearly see how angles move around the unit circle and how trigonometric values change in real time.

Advanced Math Support
Unit Circle Calculator Pro supports negative angles, decimal numbers, fractions, and π (pi) values, making it suitable for both simple and advanced trigonometry problems. Results can also be displayed directly as π-based values, which is essential for students working with standard unit circle angles.
The app includes diagrams for sine and cosine, helping users visually connect formulas with graphs. This makes it easier to understand concepts like reference angles, quadrants, and trigonometric signs.

History, Sharing & Productivity
All calculations are automatically saved in a history list, allowing users to review, sort, reload, or delete previous entries at any time. Selecting a saved entry instantly reloads it for recalculation. Users can also share solutions, making it perfect for homework, teaching, or exam preparation.
A special math keyboard ensures accurate input of fractions, pi symbols, and negative values. Smart validation highlights missing inputs or incorrect values, improving accuracy and usability.

Clean, Focused & Ad-Free
The app is completely ad-free, offering a clean, distraction-free learning experience. It is optimized for iPhone and iPad, making it a reliable math calculator app for daily study and classroom use.
