HarkHow old are your ears?
A hearing check and an eye chart in one app — honest about how each result was measured.
31
Ear age from an 8–20 kHz sweep, then a six-frequency threshold curve for each ear. Every result carries the headphones and volume it was measured on, so trends only compare like with like.

What Hark checks
- Hearing: ear age, a pure-tone threshold curve (250 Hz–8 kHz, both ears), a tinnitus tone matcher.
- Vision: a tumbling-E eye chart at one metre with live distance guidance, contrast, colour plates, an astigmatism dial and an Amsler grid.
What Hark is not
Hark is a screening app. It does not diagnose anything and it is not a medical device. Results are estimates, labelled with how they were measured. For a diagnosis, see an audiologist or an optometrist.
