Emerald Observatory for iPad vs Visolve RT for iPhone

Emerald Observatory displays a wealth of astronomical information all on one screen, in a unique but understandable format. Information includes: - 12- and 24-hour ordinary clock time - Times of rise and set for the Sun, the Moon, and the 5 classical planets - Times of the beginning and ending of twilight - Heliocentric orrery (display of the planets in orbit around the Sun) - Altitude and azimuth for the same bodies (one body at a time) - Current phase and apparent orientation and relative size of the moon - Current regions of day and night on a world map - The Equation of Time, solar time, UTC time, and sidereal time - Month, day, year, and leap-year indicator - Daily alarm (delivered as local notification if app is not running) - Eclipse simulator - Displayed times are synchronized via NTP to "atomic clock" standard, or can be set manually - Uses iPad location, or the latitude and longitude may be set manually A setting is available to allow the display to stay on continuously. If you are having any trouble with the application whatsoever, please see our FAQ on the support page listed below and then contact us through that page if your problem is not resolved. We take pride in responding promptly to all support email requests but we can't fix it if you don't report it (and we have no way to respond to Customer Reviews on the App Store). (NTP requires Internet access. Like all apps Emerald Observatory can not change the device's internal clock.)

Visolve RT for iPhone is the assistive software for people with color vision deficiency, commonly called color blindness. It can apply the following transformations to the live video preview: 1. Red-Green transform -- transforms redder colors to brighter, and greener colors to darker, 2. Blue-Yellow transform -- transforms bluer colors to brighter, and yellower colors to darker, 3. Saturation increase -- increases the saturation of all colors,4. Filtering -- darkens all colors other than the specified color, and 5. Hatching -- draws different hatch patterns according to color. Those transformations help people to distinguish colors, to find a specific color, or to guess a normal color. While Visolve for iPhone transforms colors in a still image such as a photo or a web page, Visolve RT for iPhone transforms colors in a video stream continuously. So you can watch a screen of a video or a game which consists of indistinguishable colors, with transforming the colors. Additionally, it can simulate the appearance of an image for people with color blindness. By using this feature, people with normal color vision can check how color-blind people see the world around them. Note that, however, it should be used only as a guide. We DO NOT guarantee the accuracy of the simulation image generated by Visolve.
