Aperture Area Calculator is a physics/math calculator designed to quickly and easily compute the aperture area of a lens. Features: - Instant calculations. - Results can be copied to other apps. - Includes formulas for reference. - Supports up to 16 decimal places. - Offers various unit options for each input. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. About Aperture: An aperture is a hole or an opening through which light travels. In an optical system, the aperture determines the cone angle of a bundle of rays that come to a focus in the image plane. The f-number (also called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system is the ratio of the lens’s focal length to the diameter of the entrance pupil. The focal length of an optical system measures how strongly the system converges or diverges light. The amount of light captured by a lens is proportional to the area of the aperture. Aperture Area Equations: n = f / D A = π (D / 2)² A = π (f / (2 * n))² where: D - aperture diameter f - focal length n - f-number A - aperture area Thank you for your support!

Verdict
The clearest difference is price: Flat Pattern Bend Calculator at Free against Aperture Area Calculator's $2.99. Flat Pattern Bend Calculator also leads on update cadence (every 6 weeks vs every 32 months). Aperture Area Calculator's advantage is in-app purchases (none vs 6) and ads (none vs shown). On device support there is nothing between them.
