NoLight

NoLight is a black screen camera and recording workspace designed for focused, distraction-free video capture. Record video while keeping your screen dark, or continue working inside NoLight with useful tools like Web, Notes, and Clock. KEY FEATURES BLACK SCREEN RECORDING Start recording and switch to a completely black display whenever you want. Restore the screen instantly without stopping your recording. ALWAYS-VISIBLE RECORDING INDICATOR While NoLight is recording, an on-screen indicator is shown at all times - including while the screen is black. It cannot be turned off, and there is no setting or gesture that hides it. RECORDING WORKSPACE Keep recording while using built-in tools: • Web browser • Notes • Clock • Vault CAMERA CONTROLS Choose the settings that fit your session: • Video or photo • Front or back camera • 1080p and 4K on supported devices • Microphone control • Recording background options QUICK BLACKOUT Start directly in blackout mode, or switch to the black screen while recording using supported controls. NOTES WHILE RECORDING Capture ideas, reminders, or research notes without ending your recording session. VAULT A separate space inside NoLight, unlocked with Face ID or a PIN you choose, for your own recordings, notes and browsing — much like the Hidden album in Photos or a Face ID–locked folder in Notes. It protects your own material from someone else picking up your unlocked phone. It does not change how recording is indicated. STORED ON YOUR DEVICE Recordings are saved on your device. NoLight has no accounts and uploads nothing; files leave your device only when you choose to export or share them. BUILT FOR REAL SESSIONS NoLight is useful for lectures, meetings, research, events, presentations, long recording sessions, and other situations where a bright camera screen can be distracting. NoLight respects iOS camera and microphone permissions and system privacy indicators.
