User reviews

Measure stereo output

Works great. Found our stereo side had issue with output

Good for quick measurements

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.

Good best

Good and Really, really difficult

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.
