Generate custom binaural beats around any base frequency including Alpha, Beta, Delta, Gamma, Mu, and Theta waves. Simple modern interface allows selecting Binaural Beats from 1 to 50 Hz and a Base Frequency from 20 to 1500 Hz. Binaural Beats require high quality headphones or stereo speakers. What are binaural beats? Binaural beats can help with sleep, focus, and meditation. They are an auditory illusion perceived when two different tones of slightly different frequency are presented to each ear. The frequencies are very low and each one is tuned specifically for each ear which is why headphones are required. What are the different types of binaural beats? - Alpha waves are associated with a restful and relaxed state that exists when both entering and exiting sleep. - Beta waves are associated with concentration and moderate alertness. - Delta waves are associated with deep sleep cycles and the release of physical awareness. - Gamma waves are associated with alertness and sensitive perception. - Mu waves are associated with a state of physical rest, stillness, and immobility. - Theta waves are associated with the heavy relaxation that comes from frequency, deep meditation. Directions: Drag slider to select a desired Binaural Beat from 1 to 50 Hz. Next, drag the base frequency to a tone that sounds pleasant to your ears. The binaural beat is generated around this base frequency. Adjust device volume using the on-screen volume slider to a comfortable level. You can also specify to play audio to any AirPlay supported device. Toggle audio playback using the Play/Pause button.

Diffraction Grating Calculator
Read full descriptionHide full description
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.

Verdict
The clearest difference is price: Binaural Beats Generator + at Free against Diffraction Grating Calculator's $2.99. Binaural Beats Generator + also leads on update cadence (every 3 weeks vs every 29 months). Diffraction Grating Calculator's advantage is ads (none vs shown) and iOS requirement (13 vs 15.0). On in-app purchases and device support there is nothing between them.
