Eye health apps usually pick one test. OptiCheckAI combines a Snellen acuity test, procedurally-generated Ishihara colour-vision plates, a 60-second blink-rate monitor, and a Gemini Vision AI eye scan — then layers an AI coach on top. It was found through app-gap research combining "vision test" and "dry eyes", both green-difficulty keywords.
The free screening suite
- Snellen — 8-line acuity test with Sloan letters.
- Ishihara — procedural colour-vision plates drawn on a Canvas bitmap mask (no static images to ship).
- Blink monitor — 60-second scan using Vision face landmarks to measure blink rate, a real dry-eye indicator.
- History — track results over time.
Pro: AI eye scan and OptiCoach
Pro ($4.99/mo or $29.99/yr) adds an AI eye scan — snap a close-up and Gemini Vision returns observations, self-care steps and an urgency tag (routine / soon / urgent / emergency). The OptiCoach AI chat reads your test history, so advice is personalised. Doctor-ready PDF reports and family profiles round it out.
ASO keyword strategy
Apple auto-indexes compounds like "vision test", "dry eye", "eye exam", "color blind test" and "ishihara test" from the keyword field — so a single well-chosen keyword string unlocks dozens of long-tail searches. Browse more health apps or read our app description guide.
