Record Screen vs Light Meter

Record Screen helps you capture your Phone screen in high quality, keep recordings organized, and edit or share them from one simple app. Start a screen recording with the built-in broadcast control, choose the quality you want, and record what happens on your Phone screen. After recording, your video appears in the Library, where you can review, manage, delete, and open recordings whenever you need them. Key features: • Record your Phone screen in multiple quality levels • Choose from smaller files or sharper video up to ultra quality • Save recordings automatically to an in-app Library • View recording duration and file size • Play recordings with custom controls • Adjust playback speed from slow to fast • Trim clips to keep only the part you need • Rotate video playback when a recording is sideways • Zoom and pan while watching a recording • Export videos in different qualities • Save recordings to Photos • Share recordings through Files or other apps • Use the app in multiple languages Record Screen is useful for tutorials, app demos, gameplay moments, walkthroughs, bug reports, lessons, and saving anything you need to show later. Note: protected video from streaming apps may appear as a black screen or without audio because the Phone blocks DRM-protected content during screen recording.

Middlegray is a light meter for film and digital cameras. Point your iPhone at the scene, and it gives you the shutter speed or aperture to set for the ISO you choose. BUILT TO STAY LIVE Readings update live while you meter. If the camera feed stops, the reading clears and a restart button appears, so a stale reading doesn't sit on screen looking current. If the camera pauses, for example because another app is using it, Middlegray tells you why. A held reading stays on screen even if the camera stops. METERING • Aperture priority or shutter priority • Tap the preview to meter a small spot, or tap Average to meter everything the preview shows • Hold a reading while you set your camera • Each reading shows whether it is still settling or steady • The screen stays awake while you meter • "Too dark" tells you when the light is below what the iPhone camera can measure YOUR STOPS, YOUR CAMERA • Full, ½ or ⅓ stops for aperture, shutter speed and ISO • Apertures from f/0.95 to f/128 • Shutter speeds from 1/8000 s to 30 s, with longer exposures shown as a B time • ISO 3 to 25600, with film speed presets from 50 to 3200 • Lens presets from fast prime to large format, and shutter presets for mechanical and leaf shutters • When the exposure falls between marked stops, it shows the difference, such as +⅓ • When your lens or shutter can't reach the exposure, it shows how many stops over or under CALIBRATION Every iPhone camera differs slightly. Meter the same evenly lit midtone with Middlegray and with your camera's meter, or another meter you trust, then adjust the calibration offset until they agree. The offset covers ±3 EV in ⅓ stops and is saved for your iPhone model. ACTION BUTTON On iPhone models with an Action button, set it to Middlegray's Meter Light shortcut. Press and hold the button to open Middlegray straight into live metering, releasing any held reading. HOW REFLECTED METERING WORKS Like every reflected light meter, Middlegray assumes the scene averages to middle gray. Snow or a white wall reads too dark and a black coat too bright, unless you meter a midtone or tap to meter a spot. The first launch explains this and how to calibrate. WHAT IT DOESN'T DO Middlegray reads reflected light through the iPhone camera. It doesn't do incident metering or color temperature, and B times are not corrected for film reciprocity.
