Opsino

Opsino · VoiceOver & accessibility

Name colors, even when they are hard to tell apart.

If distinguishing colors is difficult, a written color name can help with everyday tasks. Opsino pairs it with readable guidance and VoiceOver support.

Hear your reading

With VoiceOver enabled, the color name and measurement guidance are announced, including in photo mode. Buttons have accessible labels. Measure offers an additional Calibrate action. Photos have accessible controls for zooming, panning and adjusting the circle.

Understand guidance without color codes

Warnings use text and symbols. You do not need to distinguish red and green status indicators. Bright text sits on a dark surface so the camera image behind it does not interfere with reading.

Make room for longer explanations

Longer guidance scrolls and can be opened separately with Show details. The interface accommodates larger system text. A reading with warnings also gives different haptic feedback from one without detected issues.

Easier to read with less transparency

Use the iOS settings Increase Contrast and Reduce Transparency to adapt the display to your needs. Result cards stand out more clearly from the camera view or photo.

Opsino shows red as the main color and magenta as the finer shade with Increase Contrast and Reduce Transparency enabled.
Photo mode with increased contrast and reduced transparency.

Frequently asked questions

Can Opsino read results aloud?

With VoiceOver enabled, measurement results and their guidance are announced. Turn on VoiceOver in your iPhone's accessibility settings.

Can it help with color vision differences?

A written or spoken color name can make everyday identification easier. The result remains a camera estimate and should not be the sole basis for safety-critical decisions.
