ADV. Scanner turns your iPhone into the first step of a custom fit. Scan your ears, review the result, and send it to ADV. to order in-ear monitors made for you. Two ways to scan: • Ear scan — scan each ear directly with the front camera. Spoken and on-screen guidance walks you through it, so you can do it yourself in front of a mirror or with a friend's help. • Ear-impression scan — if you already have silicone ear impressions from an audiologist, place them on the printed ADV. scan sheet and sweep your phone around them. On-screen guidance shows what has been captured and the scan finishes by itself when it is complete. Then: • Review each scan before anything is sent. • Name it, add your details, and send it to ADV. from the app. • Keep a history of what you sent and when, and export a scan for your own use. • A built-in guide covers both methods. ADV. manufactures professional in-ear monitors and audio peripherals. Designed for musicians. Born in New York. www.adv-sound.com Requirements: the ear scan needs an iPhone with Face ID (iPhone X or later). The ear-impression scan needs the ADV. scan sheet, printed at 100 % on Letter, and a pair of ear impressions.

Verdict

The call

The clearest difference is review sentiment: ADV. Scanner at 67% against KLANG's 40%. KLANG's advantage is rating (4.2 vs 3.9) and update cadence (every 3 weeks vs every 2 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

KLANG holds the better App Store score, 4.2 against 3.9. Both are backed by a comparable volume of ratings — 16 and 11 respectively. Written reviews complicate that: 40% of KLANG's written reviews are positive against 67% of ADV. Scanner's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

KLANG ships an update every 3 weeks, ADV. Scanner every 2 months. The most recent releases landed on October 4, 2026 and October 8, 2026 respectively.
