Mimi Hearing Test
The Mimi Hearing Test is the easiest way to assess your hearing ability.
About the Project
Mimi's hearing technology is built on a calibrated test — without a usable test, the rest of the product doesn't exist.
The early versions worked clinically, but most people didn't finish them.
The design problem wasn't "how do we measure hearing?" — that was already solved — but "what makes someone get to the end?"
That reframe shaped four years of design work across versions 0.1 through 4.0:
how to fit a calibrated audiometric protocol into something a person can actually complete on a phone, in noise, in a few minutes, without medical context.
Project Execution
Over 250 in-person interviews drove the discovery work — watching people start, abandon, restart, second-guess, and finish the test. Each version (0.1 through 4.0) targeted a specific drop-off in that flow.
The test became shorter, calmer, and less medical-feeling without losing calibration accuracy.
By version 4.0, more than 1.5 million people had completed the test globally.
The design move that mattered most wasn't any single screen — it was the willingness to keep optimizing for completion over years.
