### 5/5 — It’s simple and it works, period

*2025-02-21*

This works exactly as advertised. I use bone conduction headphones instead of AirPods, so I couldn’t use live listen. But with this I can replace live listen and place this near the TV when the volume has to be low, or if I need a quick baby monitor!

### 5/5 — Need this for the watch!

*2025-02-14*

This would so bad to have on the iWatch

### 4/5 — Not Free

*2024-12-10*

Basically the there is no free app up if you wanna hear what people are saying over noisy background levels. This is a great example for free speech and free software development in general.

### 5/5 — Awesome

*2024-05-20, version 2.1*

Recently my mothers hearing has gone down hill and i jave been searching for an app to pair with my bone conductive headphones. Seems like all the hearing aid apps want 80-100 dollars or subscription, even before knowing if the app actually works! This works like a charm!

### 5/5 — Ok

*2024-04-16*

I wish I could hear more but ok at same time.

### 5/5 — Feedback????

*2024-03-17*

App is awesome, works just as expected so anyone giving a bad review due to feedback GET YOUR PHONE AWAY FROM YOUR EARBUDS as that’s what happens when you put ANY speaker too close to a mic.

### 5/5 — People don’t understand

*2023-11-07*

This app is great. At first I thought you could hook it up with a nearby phone and record that audio but then realized it uses your phones audio. This is great if you have Bluetooth headphones or earbuds because you can leave your phone out and hear people’s conversations when you walk away.

### 5/5 — Very good

*2023-09-13*

I Wanted to find out if my partner was cheating because she doesn't have my time anymore so I contacted this very reliable hacker (hightechcyber7 @gmail . Com ) who helped me in seeing how unfaithful she was.. He does any type of hacking so I'm recommending him to you.

### 1/5 — No good

*2022-05-18*

Nothing but feedback.  Does mot work as stated

### 4/5 — Love it! Just one flaw.

*2021-10-21*

I love the fact that you can turn your phone into a mic for Bluetooth devices! But can you add a feature where you can reverse it? Or reroute the mic to another Bluetooth device and make it play on a different Bluetooth device? If you could, I would be using this app a lot more! If you could add that feature, o would definitely recommend this to a lot of people! And it would make it more unique and original! Since I have seen a bunch of other apps do the same thing, and only that thing. Thanks! -Fellow iEavesdrop User
