Common questions
How do I get accurate results? Turn brightness up, turn off Night Shift, True Tone and Color Filters, use even daylight, and hold the device at arm’s length. The App’s “Screen tips” page walks you through it.
Is this a diagnosis? No. The App is a screening tool. If a result suggests a color vision difference, see an optometrist or ophthalmologist.
Is there a time limit? No, the timer is off by default. You can turn on a per-plate timer in Settings.
What if I see nothing on a plate? Tap “I see nothing”. Some plates are meant to be blank, and some fade for certain types of color vision.
How do I restore Pro? Open the App → Settings → Restore purchases, signed in with the same Apple Account.
How do I cancel my subscription? iOS Settings → your name → Subscriptions → Colorblind Test, or App → Settings → Manage subscription.
How do I get a refund? Purchases are handled by Apple: reportaproblem.apple.com.
Why does Color Assist need the camera? To name the color under the crosshair and apply filters live. Nothing is recorded or uploaded.
