How it works
- Open the app and allow the camera — the check starts immediately, no detours.
- Hold the camera close to skin or hair. In the inverted view, a tick stands out as a bright, clearly visible dot.
- Turn on the light, zoom in, or freeze the view whenever you need a closer look.
Why inverted colors?
A tick is small, dark, and often sits where you can barely see it — the hairline, the neck, the back of the knees. To the naked eye it passes for dirt or a shadow. Inverting the camera's colors turns that inconspicuous dark speck into a bright spot with strong contrast against the skin. That's exactly the effect TickSpot uses — read more in "Finding ticks with inverted colors".
Frequently asked questions
How does TickSpot help find ticks?
TickSpot shows your phone camera's live feed with inverted colors. A dark tick on lighter skin becomes a bright, clearly visible dot — much easier to spot than with the naked eye.
Is TickSpot free and do I need an account?
Yes, TickSpot is free and runs right in your browser. No account, no sign-up — open the app, allow the camera, done. You can also install TickSpot on your home screen, and it even works offline.
What happens to the camera images?
Everything stays on your device. TickSpot processes the camera feed entirely locally in your browser and uploads nothing. An image is only saved or shared when you explicitly choose to.
Does TickSpot replace seeing a doctor?
No. TickSpot helps you find ticks but makes no diagnoses. After a tick bite, if you notice redness, or whenever you're unsure: seek medical advice.
