### 1/5 — App does not work

### 1/5 — Not recommended

*2018-10-11*

Doesn’t decode fast tones. Basically worthless.

### 1/5 — Not worth the money

*2018-07-10*

Listened in to a fire alarm panel dialing a telephone number (10 digits). Display came up having decoded "6". Not 6 of the 10 digits.

"6". That is what it decoded out of 10 digits dialed. 1 digit. Useless.

### 1/5 — Nach Installation der App geht mein Handy nicht mehr

*2017-12-18, version 1.2*

Eine riesige Schweinerei, Und diese App handelt sich es um einen Trojaner also irgend einen Virus nach der Installation sind alle Daten weg

### 1/5 — Needs major upgrade

*2010-08-24*

Needs DTMF dial pad to encode/output DTMF tones manually and to save them as memory for speed dialing. 

Doesn't decode fast enough and gets many tones wrong.

### 1/5 — Pathetic

*2010-05-15*

Even in a quiet environment it misses numbers and doubles up on others. It will not decode tones whilst a call on the iphone is in progress so I fail to see its usefullness.

### 1/5 — Overpriced beacuse it's not fast enough.

*2010-04-27*

This could have been a cool app and a useful utility to have. But it fell short in that it does not decode tones fast enough to capture a simple fax dialing out. The entire purpose of my buying it.  

I feel giped even though it was only $2.99!!

It would only get 2/3rds of the number and not necessarily all in a row.

### 3/5 — Not bad

*2011-03-03*

I just downloaded it and it works pretty good. It does miss sometimes. It was noisy where I  was  using it but it still got the digits after I did it a couple of times.

### 5/5 — Simple, easy to use, works well.

*2023-07-02*

After I reported that the app appeared to have stopped working, the developer worked with me to troubleshoot the problem. Turns out that the microphone access got inadvertently disabled, so the developer added a check for that.

### 5/5 — Multi-Tennant Doorphone

*2021-04-15*

We had a Multi-Tennant doorphone that transmitted DTMF from the door station to the controller in the basement.  We needed to determine the transmitted numbers.  This product worked very well, and showed us what digits were sent.  From there we could make changes to the system for proper operation. Great product, and a time saver!

### 5/5 — Perfect !!!

*2012-08-26, version 1.1*

This App. works absolutely perfect :-)))

### 5/5 — Works great!

*2010-08-15*

Decodes dtmf tones even with background noise. Has many applications if you think about it.

### 4/5 — Works Perfect - but old fashioned

*2014-04-15, version 1.1*

It does what it is supposed to. 
But no iPhone 5 support...;-(

(It's working, but in 960x640)

That would be the 5th star!
