Restoring a purchase
Section titled “Restoring a purchase”Pro belongs to the Apple Account you bought it with, so you never pay twice. On a new iPhone, or after reinstalling, open Chromacy, tap Pro (the sparkles at the top right of the Measure screen), then Restore Purchases. Make sure you’re signed in to the App Store with the same Apple Account you used to buy Pro.
Can my family use Pro?
Section titled “Can my family use Pro?”Yes. Pro works with Family Sharing: if you’re in a Family Sharing group with purchase sharing turned on, everyone in the group gets Pro from one purchase. A family member may need to tap Restore Purchases once to pick it up.
Why does the answer differ from what I see?
Section titled “Why does the answer differ from what I see?”Chromacy measures the colors in the photo, and several things sit between the object and your eyes:
- The light. A white shirt under a warm bulb really is orange-ish in the photo. See lighting and white balance.
- The camera. Phone cameras adjust exposure, white balance and color to make a pleasing picture, not a measured one.
- The screen. Screens differ in color and brightness, and features like True Tone and Night Shift shift colors on purpose.
- What’s around it. The same color looks different against different backgrounds. Your eyes judge a color relative to its surroundings; Chromacy measures it on its own.
- Your eyes. Color vision varies from person to person, and the words people use for colors vary too. That’s why Chromacy shows how close the call is, not just a winner.
If Chromacy picked the wrong part of the photo, tap the subject to measure it instead.
How do lighting and white balance affect results?
Section titled “How do lighting and white balance affect results?”Light has a color of its own. Daylight, shade, warm bulbs and screens all tint everything they light, and the camera only partly corrects for it. A tinted photo gives a tinted answer.
For the most faithful reading:
- Use daylight near a window, out of direct sun, or bright, neutral indoor light.
- Avoid colored light, such as a lamp with a colored shade or light bouncing off a colored wall.
- Fill the frame with the subject, or tap it.
- Use white-balance mode: tap something in the photo that should be white or grey, such as a sheet of paper. Chromacy removes the color cast from the measurement. How it works explains the details.
Which iPhones get the on-device AI analysis?
Section titled “Which iPhones get the on-device AI analysis?”The AI analysis is part of Pro and runs entirely on your iPhone. It needs:
- An iPhone that supports Apple Intelligence: iPhone 15 Pro, iPhone 15 Pro Max, or any iPhone 16 or later
- iOS 26 or later
- Apple Intelligence turned on in Settings
On other iPhones, everything else in Chromacy, Pro included, works as usual.
What happens when the trial ends?
Section titled “What happens when the trial ends?”After your 5 trial photos, your saved results stay in your history, and you can still open and share them. To measure new photos, get Pro. See pricing.
Does Chromacy need an internet connection?
Section titled “Does Chromacy need an internet connection?”No. All the measuring, naming and AI analysis happens on your iPhone. The only thing that uses the network is the optional iCloud sync in Pro. Buying Pro goes through the App Store, which needs a connection.
Which iPhones does Chromacy run on?
Section titled “Which iPhones does Chromacy run on?”Any iPhone with iOS 17 or later.
