** FREE FOR A LIMITED TIME ** Seeing Assistant Light allows blind people to detect the light sources. During operation, the application generates a characteristic, continuous sound. The tone of that sound depends on light intensity – the more intense light, the higher the tone. User can locate the light source by turning camera when the sound has the highest pitch – camera then points to the brightest point. Sound can be turned on and off by double-tap (triple-tap on VoiceOver mode). User can not only check whether light in the room is turned on, but also whether some electronic device with display is turned on, or even whether LEDs on electrical device is turned on or off. Before buying the application please read the terms of use of the application: http://seeingassistant.tt.com.pl/en/light/terms/ -- ** Na ograniczony czas aplikacja jest darmowa ** Seeing Assistant Light umożliwia osobom niewidomym wykrywanie źródeł światła. Podczas działania aplikacja generuje charakterystyczny, ciągły dźwięk. Wysokość dźwięku zmienia się w zależności od natężenia światła. Im jaśniejsze światło, tym jest wyższy generowany dźwięk. Użytkownik lokalizuje źródło światła obracając obiektyw kamery w kierunku, któremu towarzyszy najwyższy dźwięk. Dźwięk można włączać i wyłączać poprzez podwójne stuknięcie (potrójne w trybie VoiceOver). Korzystając z aplikacji, użytkownik jest w stanie nie tylko stwierdzić czy w danym pomieszczeniu pozostawił zapalone światło ale także, czy dane urządzenie elektroniczne z wyświetlaczem zostało włączone a nawet czy dioda sygnalizacyjna jakiegoś innego urządzenia elektrycznego świeci czy pozostaje zgaszona. Przed zakupem aplikacji proszę się zapoznać warunkami korzystania z aplikacji: http://seeingassistant.tt.com.pl/light/terms/

Hear the Light turns light into sound, so you can "hear" where brightness is around you. It was designed from the ground up for people with vision loss. Point your device's back camera in any direction and listen to a tone that rises as the light gets stronger. This makes it easy to find a window, check whether a lamp is on, or tell if a device has an indicator light lit. What makes it stand out: It detects even very small device lights — such as the LED on a router, a TV on standby, or a charger. Of all the apps of this kind we have tested, it is the only one that reliably picks them up. For very faint lights, the room should be dark so they stand out from any other lighting. Extremely fast response: the tone changes instantly as you move the device, noticeably faster than other similar apps. Features: Vibration feedback with variable intensity, independent of sound: use sound, vibration, or both together. Ideal if you have trouble hearing. (Vibration requires an iPhone.) Colour recognition: hear the basic colour of a small light, for example red, green or blue. It is a helpful guide, with best results in a dark room, close to the light. Two sound modes: continuous tone or pulses. Three sensitivity levels, affecting both the sound and the vibration. Light intensity shown in lux (estimate), spoken aloud with a single tap. Built-in user guide. Fully accessible with VoiceOver. Two languages, Greek and English, adapting automatically to your device's language. Privacy first: It does not collect any personal data. No internet connection required. No advertising, no tracking. The camera is used only to measure light — it does not take or store photos. Note: the lux reading and the colour recognition are estimates based on the device's camera and may not always be exact.
