Sight Check is a free, privacy-first vision screening app you run entirely on your own phone — no eye doctor's chair required. In a few guided minutes you can check visual acuity, color vision, astigmatism, contrast sensitivity, near vision and more, then track your results over time.
Local screening flows: visual acuity, Landolt C / Tumbling E, generated color plates, color arrangement, astigmatism symptom screen, Amsler grid, contrast, and peripheral awareness. Not a medical diagnosis or certified clinical chart.
Private by design:
• No accounts, no sign-up.
• No analytics or advertising SDKs.
• No background data collection.
• All results are stored locally on your device.
Built for the whole family: voice-guided, hands-free instructions, adjustable for adults and seniors, with multiple user profiles so everyone can keep their own history.
Note: Sight Check is a screening and self-awareness tool. It does not replace a complete eye exam by a licensed professional.
Private on-device vision checks: acuity, color, astigmatism, Amsler & contrast.
