Lantern
Accessibility
Lantern explains open cancer trials and research studies in plain language. The people who need that most are often patients and caregivers reading under stress, sometimes with a vision, hearing, or motor difference on top of everything else. That makes accessibility central to how Lantern is built, not a feature bolted on at the end.
Lantern is a native iOS app built on Apple’s own frameworks, so it works with the accessibility features already in iPhone. Here is what it supports, and what each one means.
Supported features
- VoiceOver. Every screen, control, and result is labeled for Apple’s screen reader, so you can navigate and read the app by sound and touch. A trial or study result reads as a single item with a hint about what opens when you tap it, instead of a jumble of separate pieces.
- Voice Control. You can drive the whole app by voice: search, open a trial, switch tabs, change settings. The spoken names match what is on screen, so “tap Literature” or “tap Search” does what you expect.
- Larger Text. All text scales with the iPhone Dynamic Type setting, up through the largest accessibility sizes (200 percent and beyond). The reading screens, where the plain-language explanations live, grow with your chosen size so the content stays readable.
- Dark Interface. Lantern follows your system appearance and ships a full dark theme, a warm near-black rather than a harsh pure black, to ease reading in low light.
- Differentiate Without Color Alone. Status and study details are shown as words and shapes, not color-coded dots. “Recruiting,” “Phase 2,” and “Children” are spelled out, so nothing depends on being able to tell one color from another.
- Sufficient Contrast. Text meets the WCAG AA contrast standard, at least 4.5 to 1 against its background, in both the light and dark themes, checked token by token across the app.
- Reduced Motion. When Reduce Motion is turned on, Lantern settles its animations. The lantern mark stops its gentle flicker and the launch screen appears in place instead of sliding in. Screen changes fall back to simple cross-fades.
What Lantern does not include
Lantern has no video or audio content, so Captions and Audio Descriptions do not apply. If that changes in a future version, this page will change with it.
How this was checked
These features were tested with VoiceOver and Voice Control turned on, at the largest accessibility text size, in both light and dark themes, with contrast ratios measured against the WCAG AA threshold and Reduce Motion verified on the device.

Lantern is for education only. It explains public information in plain language. It does not tell you whether anyone qualifies for a trial or what a study means for your own situation. Only a care team can decide that.
