Tune the projector before your presentation in a few easy steps, or compare 3D quality on your next home theater system. Just connect to an HDMI, AirPlay, VGA or other video output and this app will display test patterns and play audio test tones with simple instructions for tuning your system. And there's more... Run TV TuneUp 3D in Executive mode, and take a series of simple steps with clear instructions to perfect the picture on your projector or display.  In 3D mode, the app provides advanced tools for measuring the ghosting or crosstalk for different combinations of displays and 3D glasses, for example. Use engineer mode to view a selection of standard test images matched to the resolution of your display. From NTSC from your iPhone's Analog Video Adapter, to full HD 1080p on your iPad's HDMI  connector, TVTuneUp3D delivers pixel-perfect synthesized test patterns and industry-standard charts provided by top test-equipment manufacturer LYNX Technik AG. Get the most from 3D TV Your iPad or iPhone can send a 3D picture to your 3D TV, and TV TuneUp 3D gives you the tools to find the best system, and get the most from it. First check and tune the stereo alignment, both Top-and-Bottom and Side-by-Side stereo modes are supported. Or use the crosstalk test to measure and minimize ghosting. It will help you find the best glasses or compare the systems in the store before you invest. Ghosting cannot be completely eliminated, but now you can reliably compare different systems, and even tune them to reduce the problem. Tune up the seats! Use the parallax samples to try different levels of 3D effect. Make sure the seats are not too close or just verify that the 3D is working, no blu-ray DVD required. Tune the tunes! With sample audio tests provided, you can optimize the stereo separation of your audio system, verify the speaker wiring polarity, and check for distortion. Note, to use AirPlay with any app as a separate display, set AirPlay to Mirroring, and the app can use the display. AppleTV with AirPlay presently support a maximum resolution of 1280x720 when mirroring or working as an external display. Features: Tune up your TV with a few simple steps Great with TV, projector, HDTV, 3D glasses Supports analog video, VGA, or HDMI adapters, and AirPlay video out Full access to all video modes for connected devices High-resolution, professional quality test patterns for standard displays Stereoscopic 3D test patterns for alignment, crosstalk measurement 3D output in Side-by-Side, Top-and-Bottom, and mono formats Retina-ready universal app, optimized for iPhone and iPad.

About

LightScope

This app uses your device's camera to measure and analyze various light properties, including illuminance, luminous intensity, and color temperature. It offers real-time histograms, contrast ratio, and noise measurements, with options for image capture and history tracking.

Highlights
  • Illuminance (lux) measurement
  • Luminous intensity (candela) calculation
  • Color temperature (K) analysis
  • Real-time histogram
  • Contrast ratio measurement
  • Image capture and storage
  • Measurement history and trends

LightScope is a comprehensive solution providing professional light measurement and analysis using your iOS device's camera sensor. 【Key Measurement Features】 • Illuminance (lux) Measurement: Calculates accurate illuminance by analyzing EXIF data from the camera sensor. Illuminance is derived using the formula: (F-number² / (Exposure Time × ISO)) × Calibration Factor. • Exposure (EV) Calculator: Converts measured illuminance to EV and suggests proper exposure combinations in standard stops for your ISO and aperture (or shutter) settings. • Luminous Intensity (candela) Calculation: Automatically calculates the luminous intensity of a light source based on the set distance. Uses the formula: Illuminance (lux) × Distance². • Color Temperature (K) & Tint Analysis: Precisely measures the light source's color temperature (1500K~15000K) and tint (green-magenta bias) by analyzing the camera's white balance sensor data — useful for identifying fluorescent and LED lighting. • Real-time Histogram: Visualizes the balance of shadows, midtones, and highlights through 16-level brightness distribution analysis. • Contrast Ratio Measurement: Evaluates the brightness ratio between bright and dark areas of a scene (based on 10th/90th percentiles) according to WCAG accessibility standards. • Noise Measurement (SNR): Calculates the signal-to-noise ratio in dB to evaluate image quality in the shooting environment. 【Advanced Features】 • Image Capture and Storage: Captures camera images at the time of measurement and stores them with measurement data. • Full-screen Image View: Zoom, pan, and rotate captured images for detailed inspection. • Gallery Saving: Save captured images to your device's photo library. • Measurement History and Trends: Save all measurements chronologically and chart trends for lux, EV, color temperature, contrast, and SNR. • Continuous Logging: Automatically record measurements at a set interval (1-60s) — great for lighting design and site surveys. • Full-Resolution Image Storage: Keep captured images at original quality for detailed inspection and gallery saving. • Export All History: Export every measurement as a CSV file or a PDF report. • Notes & Location Tags: Attach notes to measurements and optionally save the measurement location. • Home Screen Widget: See your last measurement (lux, color temperature, contrast, SNR) right on the home screen. • Camera Full-screen Mode: Hide panels to focus on the camera view while checking key measurements via a mini info panel. • Measurement Lock: Freeze exposure and white balance for stable, steady readings. • Spot Metering: In full-screen mode, tap anywhere to meter around that point. • Perfect Dark/Light Mode Support: All UI elements automatically adapt to the system theme. 【User Settings】 • Calibration Wizard: Enter a reading from a reference lux meter and the calibration factor is calculated automatically. Manual slider adjustment is also available. • Distance Setting: Set the distance to the light source for precise luminous intensity (cd) calculations. • Front/Rear Camera Selection: Choose the appropriate camera for your measurement situation. 【Technical Features】 • Support for measuring various light source types: natural light, LED, fluorescent, incandescent, etc. • Color temperature and tint sourced directly from the camera ISP's white balance estimation for reliable readings • 10-frame moving average filter for measurement stabilization • Center-weighted or spot (tap-to-meter) analysis for accurate evaluation of the main subject • Automatic exposure quality assessment based on histogram analysis Perfect tool for photographers, videographers, lighting designers, UI/UX developers, and anyone who needs accurate light measurements.

Verdict

The call

The clearest difference is price: TV TuneUp 3D at $1.99 against LightScope's $9.99. TV TuneUp 3D also leads on device support (4 vs 2) and iOS requirement (7.1 vs 16.6). LightScope's advantage is update cadence (every 2 weeks vs every 34 months) and review sentiment (42% vs 29%). On ads, in-app purchases and monetization model there is nothing between them.
