Features

Everything a pro calibrator does.
Explained in plain English.

◎

Guided calibration

Seven clear steps with tips for your exact monitor and meter. White point, brightness and gamma set and verified, with an ICC profile installed for you.

☀

Room light & colour

The diffuser arm measures your room in lux and Kelvin, then recommends the right screen brightness and warns about light that misleads your eyes.

⟳

Auto room profiles

Every 15 minutes it checks the room and switches between your Night, Normal and Day calibrations, changing profile and brightness together.

✓

ΔE2000 verification

30 real-world colours: greys, five skin tones, bridal red, gold zari and ColorChecker colours, each measured through your profile.

▦

Uniformity heat-map

Nine-point check shows whether corners are darker or tinted, so you know where on the screen to judge critical skin tones.

✎

What changed report

Before and after: brightness, white colour, grey balance, contrast and colour range, with a plain-English grade after every calibration.

⎙

PDF certificate

A one-page A4 certificate of your screen's accuracy. Keep it for your records or show clients your editing screen is verified.

⏰

Recalibration reminders

Monitors drift. After 25 days the Dock, menu bar and a notification remind you, with one click to recalibrate.

Room-aware

Your room changes.
Your colour shouldn't.

Calibrate once for each light level. CeleBrat Calibrate watches the room from the menu bar and loads the matching calibration and brightness, only after two readings agree, and never during Editing lock.

FAQ

Good questions.

Which meters are supported?

The X-Rite / Calibrite i1Display family: i1Display Pro, Pro Plus, Studio and ColorMunki Display. All are unlocked to full features.

Does it work with any monitor?

Yes. Calibration runs through the Mac, so it works with any external monitor or the built-in screen. Monitors that accept brightness commands over the cable get automatic brightness control.

Will Lightroom and Photoshop use the profile?

Yes. The profile is installed in macOS ColorSync, so Lightroom, Photoshop, Capture One and Safari pick it up automatically.

How often should I recalibrate?

Every 2–4 weeks. The app reminds you after 25 days for each room profile.

Why do I need an account?
