VisionCheck

VisionCheck is a free, offline vision self-screening tool that helps you
notice possible changes in your eyesight before you visit an eye doctor.
It is NOT a medical device and does NOT provide a diagnosis. It is a simple
first step — a filter that tells you whether what you're noticing is worth a
proper checkup, not a replacement for one.
WHAT'S INSIDE
• 6 standard vision self-tests: Distance (Snellen/Tumbling-E), Near vision,
Astigmatism, Contrast sensitivity, Amsler grid (macular check), and Colour
vision
• Symptom-guided mode — tell the app what you're noticing and it recommends
the right tests, or run a Full Eye Check to do all 6
• Clear green / yellow / red / urgent results with plain-language guidance
on when to see a doctor
• Works fully offline — no internet connection needed, ever
• No account, no sign-up, no login
• Bilingual — full English and Urdu (اردو) support, including spoken audio
guidance for low-literacy users
• Your results stay on your phone — nothing is uploaded anywhere
• Save a PDF summary or share a text summary to show your doctor
• Local history of past self-checks, viewable any time, and fully erasable
WHO IT'S FOR
Anyone who wants a quick, private, no-cost way to check whether their vision
has changed — especially useful where regular eye exams are hard to access.
Every result screen reminds you this is a screening tool only and encourages
a professional exam for anything outside "normal."
PRIVACY
VisionCheck collects no personal data, runs no analytics or ads, and makes no
network requests at all. Everything happens locally on your device. See the
full privacy policy for details.
IMPORTANT
This app is not a substitute for a comprehensive eye examination by a
qualified ophthalmologist or optometrist. If you experience sudden vision
loss, severe eye pain, or flashes of light, do not rely on this app — seek
emergency medical attention immediately.
