Live Scan
A tick scanner that works at arm's length.
Hold the camera over skin or parted fur. TickSentry marks candidate spots as you move, so the small dark things worth a second look are hard to walk past.

Marks candidates live
Stable markers track a spot as you move the camera, instead of flickering on every frame.
Five contrast filters
Inverted, blue, mono, orange and natural. Dark ticks in dark fur are much easier to see once the contrast is flipped.
Torch and haptics
A built-in torch for under-belly and behind-the-ear checks, with a haptic tap when a candidate is marked.
What it does not do. Live Scan uses a local contrast heuristic that runs entirely on your iPhone. It highlights what is worth a closer look. It does not decide what is a tick, and it cannot confirm that no tick is present.


Common questions
- Does the tick scanner work offline?
- Yes. Live Scan runs on your device and needs no connection. Camera frames are processed in memory and are never uploaded.
- Can it scan a person as well as a pet?
- Yes. Live Scan works on skin and on fur: behind ears, along the hairline, and anywhere you can hold the camera steady.
