Blingo – Voice Assistance is designed to support people with visual impairments, older adults, and anyone who wants a more convenient AI assistant without relying on complex touch interactions. The app allows you to speak naturally with AI, use your phone’s camera to identify your surroundings, and quickly perform preset voice commands. How to Use Open the app by voice or by double-tapping the back of your phone. When the app launches, the assistant will say: “Hello, how can I help you?” After the assistant finishes speaking (about 1–2 seconds), you can make a request or ask a question. Conversations proceed in order between you and the assistant.

Describe Surroundings Using the Camera Activation commands: “Describe surroundings”, “Describe around me” The assistant opens the camera; point your phone toward the area you want to identify and hold still for about 2 seconds. The app can recognize people, dogs, cats, vehicles, tables, chairs, books, refrigerators, TVs, computers, and more. Results are for reference only. In environments with many objects, counts may not be accurate. 3. Ask Questions & Chat with AI You can ask anything about general knowledge, reasoning, writing, poetry, math, and more. The assistant responds with voice output. The current version does not support real-time information (e.g., weather, gold price, news). An internet connection is required. You can make 20 AI queries per day. Customization Change the voice style and speaking speed. Adjust the number of reminders when no response is detected. Enable/disable camera preview when describing surroundings. Privacy & Data Policy The app does not collect, store, or share personal data. Questions and conversations are processed temporarily to generate responses and are not stored afterward. The app connects to an intermediate server to forward requests to the OpenAI API. All data is processed instantly and not stored on the app or server. Open Source This application is developed under the AGPL-3.0 license.
