Document Voice helps you scan, import, listen to, and understand documents with voice guidance—so letters, forms, reports, and PDFs are easier to follow without reading every line yourself. Whether you are reviewing mail at home, checking paperwork at work, studying course material, or helping a family member with an unfamiliar document, Document Voice turns printed and digital pages into spoken guidance you can act on. WHY DOCUMENT VOICE Important documents often arrive in small print, dense language, or multiple pages. Document Voice is built for those moments. Capture a document with your camera, import a photo or PDF, and move from raw text to understanding with tools designed for listening, not just looking. HOW IT WORKS Scan or import a document from your camera, photo library, or PDF file. Extract the text with on-device optical character recognition. Hear it read aloud, get a summary and explanation, or ask a spoken question about what you captured. Return anytime from scan history when you need to review a document again.

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.
