NItMeter — Professional Nit Measurement in Your Pocket

Features

Six Tools. One App. Zero Hardware.

Everything you need for professional luminance measurement — your standby field meter for when professional spot meters cost $2,000+.

First True Pocket Nit Meter

Measure screen luminance (Nits) with professional-grade accuracy. Your standby field meter when $2,000+ professional spot meters are out of reach. Same precision. A fraction of the cost.

Super Spot Meter — 3-in-1

Works like a traditional 1-degree spot meter with live Nit readings. But unlike legacy tools, NItMeter displays Nit, CCT, and EV simultaneously. Three measurements. One glance.

Region Nit — Area Analysis

Go beyond single-point measurement. Analyze luminance across an entire area — understand how screen brightness and background combine. A breakthrough no hardware competitor offers.

Delta Nit — Compare Instantly

Compare brightness differences between displays, scenes, or setups in real time. Perfect for HDR calibration, multi-display environments, and quality assurance workflows.

Audio Coach — Hands-Free

Real-time voice feedback guides you through every measurement. NItMeter tells you the result, explains the reason, and suggests the next step — hands on equipment, not on the phone.

Professional Insight — Export

Auto-log every measurement with photos and metadata. Export comprehensive reports in PDF or CSV. Includes Nit, EV, ftL, and CCT — ready for client delivery or documentation.

FAQ

Frequently Asked Questions

What is a Nit meter and why do I need one?

A Nit meter measures luminance — the brightness of a surface or display — in candelas per square meter (Nits). It's essential for HDR content creation, display calibration, lighting design, and quality assurance. NItMeter turns your iPhone into a professional-grade Nit meter, your standby field meter — always ready when you need it, built for those blocked by the cost of $2,000+ professional spot meters.

How accurate is NItMeter compared to hardware like the Konica Minolta LS-150?

NItMeter delivers professional-grade accuracy using your iPhone's advanced camera system and our proprietary continuous detection algorithm. While absolute accuracy depends on device calibration, NItMeter's relative measurements and Delta Nit comparisons are consistently reliable for professional workflows.

What is Region Nit and how is it different from a spot meter?

Traditional spot meters measure a single point (typically 1 degree). NItMeter's Region Nit feature analyzes luminance across an entire area — giving you average, min, max, and distribution data. This is critical for understanding how screen brightness interacts with ambient light, or evaluating uniformity across a display.

What does the Audio Coach do?

Audio Coach provides real-time voice feedback during measurement. It announces the Nit value, explains what the reading means, and suggests next steps — all hands-free. Perfect when your hands are occupied with equipment or when you need to measure multiple points quickly.

Can I export measurement data for reports?

Yes. NItMeter auto-logs every measurement with photos and metadata. Export comprehensive reports in PDF or CSV format, including Nit, EV, ftL, and CCT values. Perfect for client deliverables, QA documentation, or internal records.

What is Delta Nit?

Delta Nit lets you instantly compare brightness between two or more displays, scenes, or setups. Point at reference, point at target — NItMeter shows the difference. Essential for HDR calibration, multi-display matching, and quality assurance.

Which iPhones are supported?

NItMeter supports iPhone models with advanced camera systems (iPhone 12 Pro and later). The app leverages Apple's computational photography capabilities for accurate luminance measurement.

Is there a free trial?

Yes! Every plan includes a 7-day free trial with full access to all features. No commitment — cancel anytime before the trial ends and you won't be charged.

How does the pricing compare to hardware alternatives?

Professional spot meters cost $2,000 or more. NItMeter is your standby field meter — starts at just $1.99/month, always in your pocket when you need it.

Will NItMeter work for my industry?

NItMeter serves 12+ professional segments including HDR cinema, display calibration, lighting design, home theater, digital signage, automotive, and more. If you need to measure screen or surface brightness, NItMeter is built for you.
