### 1/5 — Doesn’t work as advertised

*2026-07-22, version 6.8.3*

Update: still not responding to my review, but will respond to others. They still will not contact me back. At least say “I’m sorry, but we cannot refund you.” But no, just take my money and ignore me. 

It is not worth the high price. Second time posting this. They won’t contact me back and apparently took my other review down.

### 5/5 — IT ACTUALLY WORKS

*2026-05-16, version 6.8.3*

Detects every noise.

### 5/5 — Great app

*2026-05-13, version 6.8.3*

I have some early signs of tinnitus due to over exposure from music. So I wanted to take my ear health more seriously. This app is great and free. You can pay for a premium version wich is great but even without it, there are a few extra little feature that are useful and cool to discover. TAKE CARE OF YOUR EARS PEOPLE. I’m only 25 and now have a constant ringing In my ear from wearing headphones all day at work at 80% volume all the time.

### 5/5 — Measure stereo output

*2026-04-30, version 6.8.3*

Works great. Found our stereo side had issue with output

### 4/5 — Good for quick measurements

*2026-03-15, version 6.8.2*

Not a fan of the premium push everywhere but you can use this to judge if a band at a bar is playing louder than a jet engine.

### 5/5 — Good best

*2026-02-20, version 6.8.1*

Good and Really, really difficult

### 5/5 — Deaf user

*2026-01-22, version 6.7.7*

I got this so that way I could at least see when my fire alarm was going off because my fire alarm goes off every single time I cook being profoundly deaf. I currently don’t have anything debt flashes that indicates HEY. This is going on that being said wow, this is an absolutely really freaking cool device. My recommendation is every time something comes up like say you know you’ve got your speech or you got your laughter or you’ve got your alarm that you also list everything out as they come through Because I’m not able to go back and click on the high thing and see exactly what that red dust was, which would help me in the event of OK I’m distracted. I’m dealing with a client. I’m dealing with a person in front of me. Overall I love the concept of this


*update for suggestion or maybe another side of it I feel the words are sometimes small and would like my screen to flash with whatever important thing is going on like when the phone rings I miss it when I’m interacting with a customer. I really was searching for something that flashed like white and said telephone in it red for fire alarm since your reader is so functional to what most sounds are such as emergency vehicles n stuff blue for police red and white maybe for fire trucks so it’s more of that visual when it happens. It’s dumb but I was debating on making something like that myself but very unsure of how to create that tbh. Again thank you I use this at work since my implant broke.  I have this and another phone to help with the captioning at the same time.  It’s a bit much but at this time I’ll take anything that helps.  I love the free feature and I hope this doesn’t change accessibility is important and finding apps that are truly accessible are one in a few.

**Developer response:** Thank you so much for taking the time to share this and for the 5-star review.

We are really glad to hear that the app is already helping you stay aware of important sounds like fire alarms. Hearing how it supports real-world accessibility use cases means a lot to us.

Your suggestion about listing and retaining detected sound events so you can go back and see what was identified is an excellent one. We understand how important this is when you are busy, distracted, or interacting with others, and we are actively evaluating this feature for an upcoming release.

Thank you again for your thoughtful feedback and for trusting the app. It helps us prioritize improvements that truly matter.

### 3/5 — Please fix Game Center pop up

*2025-09-29, version 6.6.5*

The decibel function itself is great. But idk if it is just me but it keeps popping up Game Center and it really disrupts using the decibel function. It is seriously annoying. I could watch an add but this one doesn’t even have an exit button and it is the most annoying thing in the world. People who use the app are not leisurely checking out some sound but are often under stress. The app developers should consider this

### 5/5 — DX

*2025-06-24, version 6.6.3*

Fun to use at stadiums
