RealTime AI Cam tells you what your camera is pointed at, out loud. Every part of it runs on the phone, so it works in airplane mode, on a subway, or in another country with no data. No account, no subscription, nothing to buy. WHAT IT DOES Names what is in front of you, over 600 everyday objects. What's this? describes the whole scene in a sentence and reads it to you. Hold to ask a question about what it sees, and it answers first: yes, no, or the number. Reads printed text out loud, and says numbers and dates the way a person would. Help Me Aim: say what you are looking for, a face, a page, a label, and it talks you into the shot, then takes the picture itself once you are lined up. One tap flashlight for dark rooms. Translates printed text into English. Distance to what is in front of you on iPhones with a depth sensor. LANGUAGES Built for English speakers. It reads English, and translates printed Spanish into English with no internet at all. Other languages download once from Apple, then work offline too (iOS 18 and later). WHAT STAYS ON YOUR PHONE Everything runs on your phone. The only time the app goes online is to download a language pack, once, and only if you want to translate something besides English or Spanish. English and Spanish never touch the internet. WORKS WITH VOICEOVER Every button is labeled, so you can run the whole app without seeing the screen. You can also let VoiceOver do the talking instead of the app if you prefer. HONEST ABOUT WHAT IT IS The models are small enough to live on your phone, which is why it works with no signal, and it does get things wrong sometimes. It tells you when it is unsure rather than guessing confidently. BUILT FROM WHAT USERS ASK FOR Most of what is in here came from blind and low vision users emailing me and me building it that night. If something does not work with VoiceOver, or you want it to do something it does not do yet, email info@nicedreamzwholesale.com.
