Nombri (Tally Counter) vs Diffraction Grating Calculator

The App Nombri is a powerful Tally counter. You can use the App whenever you need to count something. Use it for sports activities, for your private and professional life, for everything you want to count. - Count your running laps - Count your sit-ups - Count the cups of coffee you drink - Count the number of days left until your birthday - Count the number of days since you quit smoking - Count the visitors of an exhibition - Count the passengers entering or leaving a train or bus, if you need to decide wether to change the schedule - Count what ever you like… The App supports different types of counters: - Tally Counters, which you can use to manually count anything you want - Event Counters, which count the days since or up to a certain date - Timers, which are counting hours, minutes and seconds down to 0 There's no limit in the number of counters you can create. Each counter is configurable: - Set the initial value - Set the increment/decrement for the +/- buttons - Switch on/off sound effects, Speech output, vibration feedback - Give each counter a color. - Show the counter value within the App badge. - Enable the timestamps and history to analyze the progress over time graphically Other features: - A special mode lets you control multiple counters at once. - Control a counter from within the notification center - All counters are accessible from the Apple Watch as well. - Export the counter values - Analyze the counter data graphically

Diffraction Grating Calculator is a physics/math calculator that calculates the angles of diffracted orders of monochromatic light when shone on a reflective diffraction grating. Features: - Instant calculation. - Results are copyable to other apps. - Formulas are included as reference. - Supports up to 16 decimal places. - Supports various units 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. In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams traveling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element. Because of this, gratings are commonly used in monochromators and spectrometers. A diffraction grating is a material that contains a large number of parallel slits separated by a distance (d). This periodic separation of slits is usually on the order of micrometers. Because this distance is on the order of the wavelength of light, when light waves pass through the grating, the slits are able to cause constructive and destructive interference among the light waves. The waves will constructively interfere if the angle of reflection delays one of the waves by a whole wavelength. Diffraction grating equation: m * λ = a * sin(θm) Where: m: The order number of the diffracted image, m = 1,2,3 ... θ: Grating angle, in radians a: Grating Spacing, in lines per meter λ: Wavelength, in meters Thanks for your support and do visit nitrio.com for more apps for your iOS devices.
