Hearing training with mobile application for tinnitus: usability and clinical results of the Zumit app.
Izabella Lima de Matos, Rubens Jonatha Dos Santos Ferreira, Maria Fernanda Capoani Garcia Mondelli
PMID 41670121WHAT IT FOUND
Adults with tinnitus and normal hearing reported less distress and discomfort after six weeks of app-based auditory training.
The app was rated usable by most users, but half recommended it while a quarter did not. This is a small pre-post study with no control group.
Key findings
01Participants completed a six-week auditory training program using the Zumit app, which provided personalized frequency discrimination exercises and remote monitoring by a speech-language pathologist.
02After the intervention, the median score for tinnitus discomfort on the Visual Analog Scale dropped from 8 to 5, and the average Tinnitus Handicap Inventory score decreased by 21.47 points.
03The app received a System Usability Scale score of 77.06, categorized as very good, with 50% of users classified as promoters and 25% as detractors on the Net Promoter Score.

What it does not show
The study had no control group, so improvements cannot be definitively attributed to the app rather than time, placebo effect, or natural fluctuation. The sample was small (23 participants) and strictly limited to adults with normal hearing, so results do not apply to patients with concurrent hearing loss. The intervention was short-term (six weeks), providing no data on long-term adherence or sustained benefits. A 20.7% dropout rate suggests that usability or engagement issues may affect real-world completion. The analysis excluded participants who did not complete the full protocol, potentially biasing results toward those who tolerated the intervention well.
Declared interests
The authors declared no conflicts of interest. The study was conducted at a university teaching clinic accredited by the public health system (SUS).
The easy way to misread this
Do not assume the app caused the symptom reduction. Without a control group, these improvements could result from natural variation or placebo effects. Additionally, the benefit applies only to adults with normal hearing; it is unclear if this works for patients with hearing loss.
